B1A24-KEY NOT PROGRAMMED

For a complete wiring diagram, refer to appropriate SYSTEM WIRING DIAGRAMS article .

THEORY OF OPERATION

Whenever a Fob-Integrated-Key (FOBIK) is inserted in the Wireless Ignition Node (WIN) basestation, the WIN performs a self test and resynchronization routine. During the routine, the WIN interrogates the FOBIK, performing various validity and performance tests. The repair of this fault condition relies on the programmed status of the FOBIK.

During interrogation, the FOBIK sends a low frequency (LF) signal to the WIN that includes the FOBIK identification information.

This DTC sets if the WIN receives the default, secret key status from a FOBIK. Once set, this DTC will remain active until a valid, programmed FOBIK is inserted in the basestation and rotated through the ON position.

Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding. Refer to WIRELESS IGNITION NODE (WIN) PRE-DIAGNOSTIC PROCEDURE .

1. VERIFY THAT THE DIAGNOSTIC TROUBLE CODE (DTC) IS ACTIVE NOTE: Verify that the FOBIK in use is the FOBIK causing the DTC to set. Turn the ignition on. NOTE: Before continuing, review and check for the following: Review the repair history of the vehicle. Make sure that the vehicle has the correct PCM and WIN installed by verifying the part numbers. With the scan tool, make sure that the PCM and WIN are programmed correctly. Compare the PCM VIN to the WIN VIN and ensure the two VINs match. With the scan tool, record and erase the DTCs. Perform two ignition cycles, leaving the ignition switch on for a minimum of one minute per cycle. With the scan tool, read the active DTCs. Does the scan tool display; B1A24-KEY NOT PROGRAMMED Yes Go To 2 . No Perform the WIN INTERMITTENT TEST. Refer to «STANDARD PROCEDURE»(/jeep/grand-cherokee/wk2-2010-2013/remont/door-locks-anti-theft-systems/#wireless-ignition-node-win-electrical-diagnostics) .
2. ENGINE WILL NOT CRANK NOTE: When diagnosing any WIN system concern, all the FOBIKS should be present If this vehicle does not crank, use the table below to determine if the key is functional or not. With the scan tool under Data Display, Bussed Outputs, put the key in each position and check the "Ignition Status". Then with the key in the Run position, check "Valid Skim Key" and "SCREEM Status" reported by the WIN (or WCM). Compare all six readings with the "Good Key" column. If the engine does crank, answer "Yes" to the question below. BUSSED OUTPUTS Ignition Status Good Key Bad Key (Failed) Wrong Key New Key (Blank) Ignition Position = Lock -------------- or Lock -------------- -------------- -------------- or Lock Ignition Position = Acc.

B1A25-INVALID KEY

For a complete wiring diagram, refer to appropriate SYSTEM WIRING DIAGRAMS article .

Whenever a Fob-Integrated-Key (FOBIK) is inserted in the Wireless Ignition Node (WIN) basestation, the WIN performs a self test and resynchronization routine. During the routine, the WIN interrogates the FOBIK, performing various validity and performance tests. The repair of this fault condition relies on whether the ID of the FOBIK is recognized as valid in the WIN.

During interrogation, the FOBIK sends a low frequency (LF) signal to the WIN that includes the inserted FOBIK ID.

This DTC sets if the WIN receives an ID from the FOBIK that does not match any of the eight possible FOBIK IDs currently programmed in the WIN. This DTC will remain active until a valid, programmed FOBIK is inserted in the basestation and rotated through the ON position.

Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding. Refer to WIRELESS IGNITION NODE (WIN) PRE-DIAGNOSTIC PROCEDURE .

1. VERIFY THAT THE DIAGNOSTIC TROUBLE CODE (DTC) IS ACTIVE NOTE: An external Radio-Frequency Identification (RFID) key (and/or pass/radio key), such as one used to gain access to a 24 hour gym, can cause this DTC to set and create a no start condition. Inspect the customer's key chain for any type of RFID key. If one is not found, question the customer to see if a spare key chain has this RFID key on it or if it was removed from the original key chain before the vehicle was released for service. If a RFID key is present, remove the ignition key from the vehicle and remove the RFID key from the key chain. For GPEC equipped vehicles, disconnect the battery and wait a minimum of five minutes, reconnect and attempt to start the vehicle. For NGC equipped vehicles, turn the ignition on a minimum for one hour, and then attempt to start the vehicle. If the vehicle does not start, continue with the diagnostic test. NOTE: Verify that the FOBIK in use is the FOBIK causing this DTC to set. Turn the ignition on. NOTE: Before continuing, review and check for the following: Review the repair history of the vehicle.

B1A28-ECM MISMATCH WITH SKIM

For a complete wiring diagram, refer to appropriate SYSTEM WIRING DIAGRAMS article .

For the engine to start, the Sentry Key Immobilizer (SKIM) feature of the Wireless Ignition Node (WIN) and the Powertrain Control Module (PCM) must successfully communicate data over the data bus. Once the WIN sends the message that a valid Fob-Integrated-Key (FOBIK) is being used, the PCM and WIN perform a "handshake" routine, encrypted with the VIN, to validate this information, and a match allows the engine to run when the ignition state transitions to START. The repair of this fault is determined by the ability of the WIN and PCM/ECM to complete a successful handshake routine over the bus.

Whenever a valid FOBIK is inserted in the basestation and turned to the ON position, the WIN/PCM handshake takes place. The WIN validates that the message is sent to, and received by the PCM.

When a valid FOBIK is used and the WIN receives a mismatching cryptology code from the PCM as part of the routine, the WIN will send the command to flash the Security warning lamp and set this DTC as active. The engine will not start and the DTC will remain active until the WIN and PCM complete a successful handshake.

B1A29-SKIM BASESTATION MISMATCH

For a complete wiring diagram, refer to appropriate SYSTEM WIRING DIAGRAMS article .

For the engine to start, the Sentry Key Immobilizer (SKIM) feature of the Wireless Ignition Node (WIN) and the Powertrain Control Module (PCM) must successfully communicate VIN data over the serial data bus. Once the WIN sends the message that a valid Fob-in-Key (FOBIK) is being used, the PCM and WIN perform a "handshake" routine to validate this VIN information, including a positive response from the PCM which allows the engine to run when the ignition state transitions to START. The repair of this fault is determined by the WIN recognition of a valid FOBIK and the ability of the WIN and PCM to complete a successful VIN handshake routine over the bus.

Whenever a FOBIK is inserted in the basestation, the WIN determines its validity status. If determined valid, the WIN allows rotation to the ON position and the WIN/PCM handshake takes place.

When an invalid FOBIK is used and the WIN receives a mismatching or no secret key data from the FOBIK, the WIN will send the command to illuminate the Security warning lamp, send an invalid key status in the handshake with the PCM, and set this DTC as active. The "B1A28 ECM/PCM Mismatch with SKIM" DTC will probably be accompanied along with this B1A29.

B1A6C-SECRET KEY MISMATCH

For a complete wiring diagram, refer to appropriate SYSTEM WIRING DIAGRAMS article .

Whenever a Fob-Integrated-Key (FOBIK) is inserted in the Wireless Ignition Node (WIN) basestation, the WIN performs a self test and resynchronization routine. During the routine, the WIN interrogates the FOBIK for the secret key information and start the vehicle. The repair of this fault condition relies on whether the current secret key in the FOBIK is recognized by the WIN.

During interrogation, the FOBIK sends a low frequency (LF) signal to the WIN that includes the current secret key.

This Diagnostic Trouble Code (DTC) sets if the WIN receives a secret key ID from the FOBIK that is not the correct secret key value stored in the WIN. This DTC will remain active until a valid, programmed FOBIK, with the correct secret key is inserted in the basestation and rotated through the ON position.

Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding. Refer to STANDARD PROCEDURE .

ATTEMPT TO REPRODUCE THE CONDITION In the event the customer complaint cannot be duplicated due to an intermittent condition in the theft/security system, the following may aid in attempting to reproduce the condition. Using the wiring diagram/schematic as a guide, inspect the wiring and connectors related to the stored code or component in question. Look for chafed, pierced, pinched, or partially broken wires and broken, bent, pushed out, spread, corroded, or contaminated terminals. If the customer concern was related to a specific Fob-Integrated-Key (FOBIK), ensure the FOBIK in question is used while attempting reproduce the condition. Reconnect any disconnected components and harness connectors and ensure they are properly seated. If numerous trouble codes were set, use a schematic and inspect any common ground or supply circuits. Was the source of the intermittent condition located? Yes Make the appropriate repairs and perform the WIN VERIFICATION TEST. Refer to «STANDARD PROCEDURE»(/jeep/grand-cherokee/wk2-2010-2013/remont/door-locks-anti-theft-systems/#wireless-ignition-node-win-electrical-diagnostics) . No The problem cannot be found at this time. If repeated intermittent failures are encountered that cannot be reproduced and the condition has prompted multiple customer visits to the dealership, document any findings on the repair order.

WIRELESS IGNITION NODE (WIN) PRE-DIAGNOSTIC PROCEDURE

Before attempting to repair any WIN system, technicians should be familiar with and fully understand the system operation. for complete details. Refer to OPERATION . The following should be used as a checklist to be completed in its entirety prior to referencing specific WIN diagnostic procedures.

1. FOLLOW THE BASIC OUTLINE SET FORTH IN THE SIX-STEP TROUBLESHOOTING PROCEDURE Verification of complaint. Verification of any related symptoms. Symptom analysis. Problem isolation. Repair of isolated problem. Verification of proper operation.
2. TAKE INTO ACCOUNT CURRENT VEHICLE CONDITION, REPAIR HISTORY, AND TECHNICAL SERVICE BULLETINS (TSBs) Verify there are no outward signs of vehicle damage that could impact the proper operation of the theft or security system. Check for aftermarket vehicle accessories that may have been installed improperly or could interfere with the system Check the vehicle repair history for repairs that may relate to the current condition. Perform a check of current Technical Service Bulletins (TSB) for the WIN system related to the customer concern. If a TSB applies, follow the procedure outlined in the TSB.
3. DIAGNOSE ONLY THOSE FAILURES THAT ARE ACTIVE AND CAN BE REPRODUCED Check the control module that is central to the subsystem which is exhibiting the condition for the active DTCs. For an intermittent failure that is not current at the time of vehicle inspection, and perform the WIN INTERMITTENT TEST and document the event on the repair order. Refer to «STANDARD PROCEDURE»(/jeep/grand-cherokee/wk2-2010-2013/remont/door-locks-anti-theft-systems/#wireless-ignition-node-win-electrical-diagnostics) .
4. ADDRESS ACTIVE DIAGNOSTIC TROUBLE CODES (DTCS) IN THE CORRECT ORDER As a general rule, for any WIN module that exhibits more than one active DTC, address the codes in the order indicated: Low/High Voltage and Serial Data Loss of Communication Codes Module Internal Failure and Configuration Mismatch Codes Circuit specific DTC failures Should the malfunction still be present after conducting this Pre-diagnostic Procedure, technicians should continue to the appropriate DTC procedure or symptom diagnostic.

WIN VERIFICATION

For a complete wiring diagram, refer to appropriate SYSTEM WIRING DIAGRAMS article .

Perform the following after completion of a diagnostic repair

Note. When entering the Personal Identification Number (PIN), care should be taken because the WIN will only allow three consecutive attempts to enter the correct PIN. If three consecutive incorrect PINs are entered the WIN will Lock Out the scan tool. To exit Lock Mode, the ignition key must remain in the Run position for one hour. All accessories must be off. A battery charger connected to the battery during this time period is recommended.

Note. On vehicles equipped with a Base Tire Pressure Monitoring (TPM) system, when the WIN and/or the spare tire pressure sensor is replaced with a new unit, a diagnostic scan tool MUST be used to run a routine that allows the WIN to be programmed with the ID number and location of the spare tire pressure sensor mounted in the wheel of the spare tire. Follow the programming steps outlined in the diagnostic scan tool for "Learn Spare Tire Sensor ID" under "Miscellaneous Functions" for the "WIN" menu item as appropriate. In addition, if the WIN is replaced, the spare tire must be dismounted from its wheel to access and note the ID number on the spare tire pressure sensor so that the ID code for that sensor can be programmed into the new WIN.

1. Reconnect the previously disconnected components and connectors.
2. Obtain the vehicle's unique Personal Identification Number (PIN) assigned to it's original WIN. This number can be obtained from the original vehicle invoice or from your Service Manager or Parts Manager.

PCM & WIN REPLACEMENT

Note. If the Powertrain Control Module (PCM) and the WIN are replaced at the same time, program the PCM VIN into the PCM first.

Note. The PCM stores the secret key information. If the WIN ever needs to be replaced, the secret key information can be retrieved from the PCM and then transferred to the WIN for security use.

During PCM/ECM replacement, use the following steps to verify the transfer of the secret key information from the WIN to the new PCM

1. If the PCM is to be replaced, first, replace the PCM/ECM with the original WIN still connected to the vehicle. If the PCM is not being replaced, go to step 3.
2. Using the appropriate Service Information to program the new PCM/ECM. (This will verify the Secret Key Transfer from the original WIN into the new PCM/ECM).
3. Now replace and program (WIN Replaced) the WIN (if necessary). This will cause the WIN to receive the Secret Key from the PCM/ECM back into the new WIN. NOTE: If this vehicle is equipped with a Steering Column Lock Module, it must be replaced along with the WIN. Whenever a WIN is replaced the Steering Wheel Lock Module MUST also be replaced.
4. Using the scan tool, select Miscellaneous Functions, WIN. Then select the desired procedure and follow the display on the scan tool.
5. If the vehicle is equipped with the Base Tire Pressure Monitoring System, program the Placard Pressure Values into the WIN.
6. Make sure all the customer's keys have been programmed into the new module if necessary. NOTE: If the WIN module was replaced and the vehicle is equipped with the Passive Entry System (PEM), with the scan tool, perform the "PEM Replace" routine in the PEM after the FOBIKS have been programmed.
7. Using the scan tool, erase all DTCs. Perform five ignition key cycles, leaving the key on for at least 90 seconds per cycle.
8. Using the scan tool, read WIN DTCs.

1. Are there any WIN DTCs present? Yes Repair not complete, go to the appropriate diagnostic information and perform the appropriate diagnostic procedure. No Repair is complete.
