Control System (Vehicle Communication): Other Mazda Tribute II

COMMUNICATIONS NETWORK

Vehicle communication utilizes the controller area network (CAN) communications. The CAN allows many modules to communicate with each other on a common network. CAN in-vehicle networking is a method for transferring data among distributed electronic modules via a serial data bus.

Without serial networking, inter-module communication requires dedicated, point to point wiring resulting in bulky, expensive, complex, and difficult to install wiring harnesses. Applying a serial data network reduces the number of wires, combining the signals on a single network. Information is sent to the individual control modules that control each function.

The vehicle has 2 module communication networks

1. Medium speed controller area network (MS-CAN)
2. High speed controller area network (HS-CAN)

Both networks are connected to the data link connector (DLC). This makes diagnosis and testing of these systems easier by allowing one scan tool to be able to diagnose and control any module on the 2 networks from the connector. The DLC can be found under the instrument panel between the steering column and the audio control module (ACM).

TERMINATION MODULE REFERENCE CHART

Network Termination

The CAN uses a network termination circuit to improve communication reliability. The network termination of the CAN bus takes place inside the termination modules by termination resistors. Termination modules are located at either end of the bus network. As network messages are broadcast, in the form of voltage signals, the network voltage signals are stabilized by the termination resistors. Each termination module has a 120 ohm resistor across the positive and negative bus connection in the termination module. With 2 termination modules on each network, and the 120 ohm resistors located in a parallel circuit configuration, the total network impedance, or total resistance, is 60 ohms.

Network termination improves bus message reliability by

1. Stabilizing bus voltage
2. Eliminating electrical interference.

Gateway Module

The instrument cluster (IC) is the gateway module, translating HS-CAN to MS-CAN and vice versa. This information allows a message to be distributed throughout both networks. The IC is the only module on this vehicle has this ability.

MODULE CONTROLLED FUNCTIONS

Note. The smart junction box (SJB) is also known as the generic electronic module (GEM).

Note. The time out for the battery saver relay and the accessory delay relay (both are controlled by the SJB) is 1 minute if the vehicle has less than 80 km (50 miles). Once the vehicle passes the approximate mileage threshold of 80 km (50 miles), the time out for both relays will be the normal 10 minute time out, as described by the Owner's Literature. For the battery saver relay, see PINPOINT TEST 9: THE BATTERY SAVER DOES NOT DEACTIVATE AFTER TIME-OUT . For the accessory delay relay, see PINPOINT TEST 9: THE DELAYED ACCESSORY IS INOPERATIVE/DOES NOT OPERATE CORRECTLY .

The SJB is the only multifunction electronic module on this vehicle. The SJB is a combination of a multifunction electronic module and a central junction box (CJB). The following systems are controlled by the SJB

1. Autolocks
2. Exterior lamps
3. Illuminated entry and interior lamps
4. Keyless entry keypad
5. Power door locks
6. Remote keyless entry (RKE) system
7. Tire pressure monitoring system (TPMS)

The SJB is located under the front (passenger side floor) console.

Post Crash Alert

The post crash alert function is controlled by the SJB. If the restraints control module (RCM) determines an impact of severity enough to deploy the air bags has occurred (the air bags may or may not be deployed by the RCM), the RCM sends a message to the instrument cluster (IC) over the high speed controller area network (HS-CAN), which sends a message to the SJB over the medium speed controller area network (MS-CAN) and the SJB activates the post crash alert function by sounding the horn 3 times, then off for 4 seconds, then on 3 times, etc, until the battery dies or the function is turned off. The hazard lamps also flash with the horn sounding, however, the hazard lamps keep flashing during the horn off cycle.

The post crash alert function can be turned off by

1. pressing the hazard switch (may need to be pressed more than once).
2. pressing the integrated keyhead transmitter (IKT) key UNLOCK button.
3. pressing the PANIC button.

This feature acts similar to a perimeter alarm, but the horn cycle is different. Turning the ignition to the ON position will not deactivate this function, but will deactivate an activated perimeter alarm. This vehicles does not have a perimeter alarm.

The post crash alert function cannot be configured off.

Module Configuration and Parameter Chart

MODULE CONFIGURATION AND PARAMETER CHART

Scheme 23

Definition of Terms

The following are definitions of configuration terms

Module Reprogramming

Module reprogramming (also referred to as "flashing") is a scan tool process which updates the strategy/calibration in a module. Reprogramming a module with the same level of software will not improve module operation or repair a hardware failure. Module reprogramming is automatically carried out during PMI when a later strategy/calibration is available.

Note. Module reprogramming should be limited to circumstances where a published Technical Service Bulletin (TSB) procedure recommends doing so.

Note. A module cannot communicate with other modules on the communication network while being reprogrammed. Clear any network communication DTCs which may have been set in other modules during reprogramming.

Programmable Parameters

Programmable parameters are customer preference items that may be modified by the dealer via scan tool or in some cases modified by the customer following a procedure listed in the vehicle Owner's Literature. While many configuration options may exist for a module, only a few of these options are programmable parameters.

Module Address

A unique module address is assigned to each module on the network for identification.

As-Built Data

As-Built data is a VIN-specific module configuration record. During vehicle build, the configuration from all modules is downloaded and stored in the As-Built database. As-Built data will not reflect customer preference items that have been changed from the default state. These items will need to be changed using programmable parameters after the module is configured.

Note. It is not necessary to obtain As-Built data unless directed to do so by the scan tool. This data may be accessed from the technician service publication website.

PASSIVE ANTI-THEFT SYSTEM (PATS)

Note. The smart junction box (SJB) is also known as the generic electronic module (GEM).

The passive anti-theft system (PATS) consists of the following components

1. Anti-theft indicator (located in the instrument cluster ([IC])
2. Encoded ignition integrated keyhead transmitter (IKT) PATS key(s) (the key contains a transponder and a remote keyless entry [RKE] transmitter)
3. Encoded (the key contains a transponder) ignition PATS keys (not factory equipped, but may be used in place of IKT keys)
4. PATS transceiver
5. IC
6. PCM

PATS uses radio frequency identification technology to deter a drive-away theft. Passive means that it does not require any activity by the user.

The vehicle is equipped with 2 IKT PATS keys. The IKTs operate as a standard PATS key with an RKE transmitter incorporated into the keyhead. The IKTs require batteries for the RKE transmitter to operate. A maximum of 4 IKT keys can be programmed to operate the vehicle. If more than 4 IKT keys are programmed, the RKE portion of the additional keys do not operate and the SJB and the IC set a memory full DTC (B1138 - Memory Full). These additional keys will start the vehicle, but will not operate the RKE system. If additional PATS keys are desired, a standard PATS key (a non-IKT key) can be used. For the purposes of this service information, the PATS portion of the IKT key is referred to as a PATS key.

Passive Anti-Theft System (PATS) Function

The PATS function is controlled by the IC. The PATS uses the IC to carry out all of the PATS functions such as receiving the identification code from the PATS key, issuing a signal to the PCM to control the starter and fuel injectors enable, and initiating the key interrogation sequence when the ignition key is turned to the ON or START position. Because of the interaction between the IC and the PCM, there are parameters that must be set if the IC or the PCM (or both) are replaced. See PASSIVE ANTI-THEFT SYSTEM (PATS) PARAMETER RESET . If the IC must be replaced for any reason (PATS concerns or an IC concern), the PATS keys also may be programmed into the new IC. See INTEGRATED KEYHEAD TRANSMITTER (IKT) KEY PROGRAMMING USING DIAGNOSTIC EQUIPMENT . All elements of PATS must be functional before the vehicle will start. If any of the components are not working correctly, the vehicle will not start.

PATS is active only for a few seconds when the vehicle is starting. It is not a PATS concern if the vehicle stalls after it has been running for a minimum of 3 seconds. PATS will not disable a running vehicle.

PATS may cause a vehicle no start due to either the fuel injectors or the starter not operating (starter relay does not close) or both. Always check for PATS DTCs from the IC and DTCs from the PCM when a no-crank or no-start condition exists. A low state of charge in the vehicle battery may cause the PATS to allow starter operation, but prevent the fuel injectors from operating.

If the anti-theft indicator does not prove out (it may be either flashing or glowing steadily) and one (or both) of the previous conditions (fuel injectors and/or starter inoperative) are present, it may be due to a PATS issue. If the anti-theft indicator proves out, it may not be a PATS issue. If the anti-theft indicator does not illuminate at all, it may be an IC issue. See SYMPTOM TROUBLESHOOTING CHART - PASSIVE ANTI-THEFT SYSTEM (PATS) .

PATS is not compatible with aftermarket remote start systems, which allow the vehicle to be started from the exterior of the vehicle. These systems may reduce the security of the vehicle, and also may be the cause of no-start concerns. Remote start systems must be removed from the vehicle before any PATS-related no-start concerns are investigated.

Unlimited Key Mode

PATS contains a feature called unlimited key mode. This feature allows a customer to program more than 8 vehicle keys, if requested. Each vehicle in unlimited key mode is set up with a special unlimited transponder security key code. This allows all the customer vehicles to share the same mechanically cut keys. For an individual customer, any randomly selected security key that has been previously mechanically cut and electronically programmed to the vehicle is acceptable.

The unlimited key mode is enabled, a maximum of 4 IKT keys can be programmed to the vehicle for RKE functionality. If more keys are required, they should be standard PATS keys. If more than 4 IKT keys are programmed to the vehicle, the SJB and the IC will set DTC B1138 (memory full) and only 4 IKT keys will have RKE functionality, however, all of them will start the vehicle, if programmed correctly. See SPARE KEY PROGRAMMING - UNLIMITED KEY MODE .

Scheme 24

1. Remove the steering column opening cover. See «INSTRUMENT PANEL - EXPLODED VIEW»(ref-348677-S01092538542009112700000)
2. Remove the 3 screws and the lower steering column shroud.
3. Remove the passive anti-theft system (PATS) transceiver. Disconnect the electrical connector.
4. To install, reverse the removal procedure.

Note. Replacement of the PATS transceiver does not require the PATS keys to be programmed into the instrument cluster (IC) again.

ANTI-THEFT SECURITY ACCESS

Note. The anti-theft security access procedure is used to obtain passive anti-theft system (PATS) security access. PATS security access must be granted to erase ignition key codes, program ignition key codes, enable/disable unlimited key mode, set unlimited transponder key ID, reset PATS parameters in the instrument cluster (IC) and the PCM, and enable/disable the spare key programming switch (PID SPAREKEY). The anti-theft security access procedure invokes a 10-minute time delay prior to granting security access during which the scan tool must remain connected to the vehicle. Once security access is granted, a security access command menu is displayed which offers various command options.

Note. Once security access has been granted, multiple security access commands should be executed (if necessary) prior to exiting the command menu. This avoids an additional security access procedure and the associated 10 minute time delay.

1. From the scan tool, enter TOOLBOX. Select: BODY - SECURITY - PATS Functions, and follow the onscreen instructions to ENTER SECURITY ACCESS. This procedure takes approximately 10 minutes to carry out, during which time the ignition switch must be in the ON position and the scan tool must be connected to the vehicle.
2. After the 10-minute security access procedure is completed, follow the on-screen instructions and a new menu is displayed with command options. Select only those functions required before exiting out of this menu. Do not select more functions than the procedure calls for. Once exited out of this menu, the security access procedure must be repeated again to carry out additional commands.

KEY PROGRAMMING SWITCH STATE CONTROL

Note. The spare key programming switch is a programmable switch which provides the capability to enable/disable the normal customer spare key programming procedure detailed in the Owner's Literature. It must read ENABLE if more than 2 keys need to be programmed into the instrument cluster (IC). See KEY PROGRAMMING USING TWO PROGRAMMED KEYS . This programmable switch is provided as a convenience for rental company fleets or other fleet purchasers who may not want the spare key programming procedure available to the vehicle driver.

Note. The spare key programming switch state can be viewed with the IC SPAREKEY PID.

Note. If the SPAREKEY PID reads ENABLE, up to 8 keys total can be programmed into the IC using KEY PROGRAMMING USING TWO PROGRAMMED KEYS . If the SPAREKEY PID reads DISABLED, the Key Programming Using Two Programmed Keys procedure does not function. This switch is set to ENABLE when the vehicle is built. This PID does not affect the Spare Key Programming. Using Diagnostic Equipment or the Spare Key Programming - Unlimited Key Mode procedures.

1. Insert a programmed passive anti-theft system (PATS) key (or integrated keyhead transmitter [IKT] key) into the ignition lock cylinder and turn the key from the OFF position to the ON position.
2. From the scan tool, enter TOOLBOX. Select BODY - SECURITY - PATS Functions and follow the onscreen instructions to ENTER SECURITY ACCESS. See «ANTI-THEFT SECURITY ACCESS»(ref-348648-S40744504822009112700000) .
3. From the scan tool menu select: CUSTOMER SPARE KEY PROGRAMMING ENABLE and follow the integrated diagnostic system (IDS) on-screen instructions in order to complete the procedure. CUSTOMER SPARE KEY PROGRAMMING ENABLE - spare key programming procedure is accessible. CUSTOMER SPARE KEY PROGRAMMING DISABLE - spare key programming procedure is not accessible.

Note. The default setting on delivery of all new vehicles is ENABLED, when viewing the IC SPAREKEY PID.

KEY PROGRAMMING USING TWO PROGRAMMED KEYS

Note. This procedure works only if 2 or more programmed ignition keys (they do not have to be integrated keyhead transmitter [IKT] keys) are present. If 2 programmed passive anti-theft system (PATS) keys are not available, see INTEGRATED KEYHEAD TRANSMITTER (IKT) KEY PROGRAMMING USING DIAGNOSTIC EQUIPMENT .

Note. The PID SPAREKEY must be enabled for this procedure to operate. If this PID is not enabled, see KEY PROGRAMMING SWITCH STATE CONTROL in this service information, in order to enable the customer spare key programming PID. The PID SPAREKEY is set to ENABLE when the vehicle is built.

Note. If the programming procedure is successful, the new key(s) starts the vehicle and the anti-theft indicator proves-out for approximately 3 seconds. If the programming procedure is not successful and the new key(s) does not start the engine, leave the key in the ON position for at least 3 seconds, then turn the key off. Repeat the key programming procedure from Step 1. If the failure repeats, see SYMPTOM TROUBLESHOOTING CHART - PASSIVE ANTI-THEFT SYSTEM (PATS) to review the DTCs and carry out the appropriate pinpoint tests.

Note. A minimum of 2 PATS keys must be programmed into the instrument cluster (IC) before the vehicle will start.

Note. If the vehicle is in unlimited key mode, this spare key programming procedure still functions. Any 2 keys that can start the vehicle can be used to program an additional unlimited key.

Note. If additional keys are to be programmed, and the remaining keys are with the customer, or are not available, instruct the customer to refer to the Owner's Literature for instructions on programming the remaining keys. In this case, the PID SPAREKEY must be enabled.

Note. If the steps are not carried out as outlined, the programming procedure ends.

Note. Ignition keys must have a correct mechanical key cut for the vehicle and must be PATS encoded keys (contain a transponder). The key does not have to be an IKT key.

Note. This procedure is not necessary if only the PATS transceiver was replaced. Replacement of the transceiver does not erase the PATS key codes in the IC.

Note. A maximum of 8 ignition keys can be programmed to a PATS vehicle, of which up to 4 can be IKTs. If an attempt to program more than 4 IKTs occurs, the smart junction box (SJB) and the IC set a memory full DTC (B1138), and the additional IKTs will not have any remote keyless entry (RKE) function capability. If the vehicle is equipped with a message center, the IC displays the message INT KEY COULD NOT PROGRAM. The PATS portion of the additional key will function, but the RKE transmitter function will be inoperative.

1. Insert a programmed ignition key (can be an IKT or a standard PATS key) into the ignition lock cylinder and turn the key from the OFF position to the ON position.
2. Leave the key in the ON position for 3 seconds, but not longer than 10 seconds.
3. Turn the key to the OFF position and remove the first key.
4. Within 10 seconds of turning the key to the OFF position, insert a second programmed ignition key (can be an IKT or a standard PATS key) into the ignition lock cylinder and turn the key from the OFF position to the ON position.
5. Leave the key in the ON position for 3 seconds, but not longer than 10 seconds.
6. Turn the key to the OFF position and remove the second key.
7. Within 20 seconds of turning the key to the OFF position, insert the unprogrammed key (new PATS or IKT key) into the ignition lock cylinder and turn the key from the OFF position to the ON position. Leave the key in the ON position for a minimum of 6 seconds (this additional 3-second time frame allows for the RKE data transfer to take place, if programming an IKT key).
8. Start the vehicle with the new key. If it is an IKT key, verify the RKE functions. NOTE: The new key will now start the vehicle and will also operate the RKE functions, if there are 4 or fewer IKT keys programmed to the vehicle.
9. If additional programmed keys are desired, repeat Steps 1-7.

Enabling Unlimited Key Mode

Note. Unlimited key mode is intended for use by those customers who need more than 8 keys for their vehicle.

Note. If unlimited key mode is enabled, a maximum of 4 integrated keyhead transmitter (IKT) keys can be programmed to the vehicle for remote keyless entry (RKE) functionality. If more keys are required, they should be standard passive anti-theft system (PATS) keys. If more than 4 IKT keys are programmed to the vehicle, the smart junction box (SJB) and the instrument cluster (IC) will set DTC B1138 (memory full) and only 4 IKT keys will have RKE functionality, however, all of them will start the vehicle, if programmed correctly.

Note. Before programming, the new key(s) must have the correct mechanical cut for the ignition lock cylinder.

Note. The unlimited key mode is set up by creating a special, unique unlimited transponder security key code and programming this key code into all of the vehicle keys so they contain the same key code.

Note. When in the unlimited key mode, the N_KEYCODE PID will always read 2, no matter how many keys are programmed to the vehicle (after the first 2 keys have been programmed).

1. The customer must choose an 8-digit number (except for 00000000 or 00000001) to be programmed to all of their vehicles. All customer vehicles need to use the same number. Valid digits are 0-9 and the letters A-F.
2. Monitor the PID UNL_KEY_ID and compare its value against the code chosen in Step 1. It should not be the same key code. NOTE: If the PID UNL_KEY_ID is not available, unlimited key mode is turned on, and must be turned off before viewing the stored code. At this time, unlimited keys may be programmed to the vehicle. To view/change the stored code, follow the procedure for disabling the unlimited key mode below.
3. From the scan tool, enter TOOLBOX. Select BODY - SECURITY - PATS Functions and follow the integrated diagnostic system (IDS) on-screen instructions to ENTER SECURITY ACCESS. See «ANTI-THEFT SECURITY ACCESS»(ref-348648-S40744504822009112700000) .
4. Once in security access, select: "program unlimited key code" and follow the IDS on-screen instructions. Enter the 8-digit code chosen by the customer in Step 1 of this procedure and follow the IDS on-screen instructions.
5. Select: "unlimited key mode ON" and follow the IDS on-screen instructions.
6. Select: "Ignition Key Code Erase" and follow the IDS on-screen instructions.
7. Disconnect the scan tool and turn the ignition switch to OFF.
8. Insert the first PATS key into the ignition lock cylinder and turn the key to the ON position for 3 seconds (6 seconds if it is an IKT key).
9. Remove the first PATS key from the ignition lock cylinder.
10. Insert the next PATS key into the ignition lock cylinder and turn the key to the ON position for 3 seconds (6 seconds if it is an IKT key).
11. If it is desired to program additional key(s), see «KEY PROGRAMMING USING TWO PROGRAMMED KEYS»(ref-348648-S06660323172009112700000) for each additional key that needs to be programmed.

Disabling Unlimited Key Mode

Note. By disabling the unlimited key mode, the previous access code no longer operates the vehicle.

1. From the scan tool, enter TOOLBOX. Select BODY - SECURITY - PATS Functions and follow the integrated diagnostic system (IDS) on-screen instructions to ENTER SECURITY ACCESS. See «ANTI-THEFT SECURITY ACCESS»(ref-348648-S40744504822009112700000) .
2. Select: "unlimited key mode OFF" and follow the IDS on-screen instructions.
3. Select: "Ignition Key Code Erase" and follow the IDS on-screen instructions.
4. Disconnect the scan tool and turn the ignition switch to OFF.
5. Insert the first PATS key into the ignition lock cylinder and turn the key to the ON position for 3 seconds (6 seconds if it is an IKT key).
6. Remove the first PATS key from the ignition lock cylinder.
7. Insert the next PATS key into the ignition lock cylinder and turn the key to the ON position for 3 seconds (6 seconds if it is an IKT key).
8. If it is desired to program additional key(s), see «KEY PROGRAMMING USING TWO PROGRAMMED KEYS»(ref-348648-S06660323172009112700000) for each additional key that needs to be programmed. The PID SPAREKEY must be enabled.

Note. With the unlimited key mode turned off, a maximum of 8 keys can be programmed into the IC using the KEY PROGRAMMING USING TWO PROGRAMMED KEYS procedure. The PID SPAREKEY must be enabled.

REMOTE KEYLESS ENTRY TRANSMITTER PROGRAMMING

Note. This procedure is for programming conventional keyfobs only. The remote keyless entry (RKE) transmitter of the integrated keyhead transmitter (IKT) is programmed automatically during the passive anti-theft system (PATS) programming. See KEY PROGRAMMING USING TWO PROGRAMMED KEYS or INTEGRATED KEYHEAD TRANSMITTER (IKT) KEY PROGRAMMING USING DIAGNOSTIC EQUIPMENT to program the IKT.

Note. All RKE transmitters must be programmed at the same time.

Note. Do not apply the brake pedal during this sequencing, as doing so ends the sequence and the transmitters will not be programmed.

1. Electronically unlock the door locks using the door lock control switch.
2. Cycle the ignition switch from the OFF to the RUN position 8 times in rapid succession (within 10 seconds), with the eighth turn ending in RUN. If the module successfully enters program mode, it locks and then unlocks all the doors.
3. Within 20 seconds, press any button on the RKE transmitter to be programmed. The doors lock and then unlock to confirm that each RKE transmitter is programmed. Repeat this step for each RKE transmitter. NOTE: If no action is taken within 20 seconds after a transmitter has been programmed, the programming sequence ends (the doors lock and unlock to confirm that programming is complete).
4. Exiting the programming mode is accomplished if one of the following occurs: The key transitions to the OFF position 20 seconds have passed since entering programming mode or since the last RKE transmitter was programmed The maximum number (4) of RKE transmitters have been programmed
5. Check the operation of the RKE transmitter. If the door locks do not respond for the programmed RKE transmitter(s), wait several seconds and press the button again. If the door locks still fail to respond, see «LOCKS, LATCHES AND ENTRY SYSTEMS»(ref-348636-S01793907152009112700000) . (Make sure that no more than the maximum number of RKE transmitters are attempted to be programmed.)
