DTC (Diagnostic Trouble Codes)

The self-diagnostic function of the SRS unit allows it to locate the causes of system problems and store this information in memory. For easier troubleshooting, this data can be retrieved with the HDS via the data link circuit

  1. When you turn the ignition switch to ON (II), or press the engine start/stop button to select the ON mode, the SRS indicator should come on. If it goes off after 6 seconds, the system is normal, and is not currently detecting any problems.
  2. If there is a problem, the system locates and defines the problem, stores this information in the memory, and turns on the SRS indicator. The data remains in the memory even if the ignition switch is turned to LOCK (0), the engine start/stop button is pressed to select the OFF mode, or the battery is disconnected.
  3. The data is stored in memory as a diagnostic trouble code (DTC).
  4. DTCs are either latching or resetting depending on the malfunction. With resetting DTCs, the SRS indicator goes off the next time the ignition switch is turned to ON (II), or the engine start/stop button is pressed to select the ON mode, and the system is normal, but the DTC is still stored. With latching DTCs, the SRS indicator does not turn OFF until the malfunction is repaired and the DTC is cleared.
  5. When you connect the HDS to the data link connector (DLC), you can retrieve a more detailed DTC in the HDS "SRS" menu. NOTE: Only read DTCs from the SRS menu, not from SWS menus unless instructed to check SWS DTCs. SWS (ODS unit) DTCs are subcodes of SRS unit DTCs. Only troubleshoot the corresponding SRS DTCs. These SWS DTCs are cleared when you turn the ignition switch to LOCK (0), or press the engine start/stop button to select the OFF mode.
  6. After reading and recording the DTC, go to the troubleshooting procedure for that code.

Precautions

  1. Make sure the battery is fully charged. If the battery is dead or low, electrical measurements values may not be correct.
  2. Use only a digital multimeter to check the system. Make sure its output is 10 mA (0.01 A) or less when switched to the smallest value in the ohmmeter range. A tester with a higher output could damage the airbag circuit or cause accidental airbag deployment and possible injury.
  3. Whenever the ignition switch is in ON (II), the engine start/stop button is pressed to select the ON mode, or has been turned to LOCK (0), or the engine start/stop button is pressed to select the OFF mode for less than 3 minutes, be careful not to bump the SRS unit; the airbags could accidentally deploy and cause damage or injuries.
  4. Before removing the dashboard wire harness or floor wire harness, disconnect the driver's airbag inflator connector, the front passenger's airbag inflator connector, both side airbag inflator connectors, both side curtain airbag inflator connectors, and both front seat belt tensioner connectors.
  5. Do not touch a tester probe to the terminals in the SRS unit or harness connectors, and do not connect the SRS unit terminals or the sensor terminals with a jumper wire. Use only the back probe set and the digital multimeter. Back probe spring-loaded lock type connectors correctly.

How to Read DTCs

  3. Turn the ignition switch to ON (II), or press the engine start/stop button to select the ON mode.
  4. Make sure the HDS communicates with the vehicle and the SRS unit. If it does not communicate, inspect the power line of SRS unit, fuses, and ground, and if there is not any abnormality found, then go to the DLC circuit troubleshooting (see «DLC CIRCUIT TROUBLESHOOTING»(/acura/zdx/i-2009-2013/remont/communication-devices/#communication-systems-f-can-k-line__dlc-circuit-troubleshooting) ).
  5. Use the HDS to check for SRS DTCs.
  6. Read and record the DTCs. NOTE: Only read DTCs from the SRS menu, not from SWS menus unless instructed to check SWS DTCs. SWS (ODS unit) DTCs are subcodes of SRS unit DTCs. Only troubleshoot the corresponding SRS DTCs. These SWS DTCs are cleared when you turn the ignition switch to LOCK (0), or press the engine start/stop button to select the OFF mode. Do not clear the DTCs until instructed by the troubleshooting procedure.
  7. Turn the ignition switch to LOCK (0), or press the engine start/stop button to select the OFF mode, then wait for 10 seconds.
  8. Disconnect the HDS from the DLC.
  9. Do the troubleshooting procedure for the DTC.

Troubleshooting Intermittent Failures

If there was a malfunction that sets a DTC, but it does not recur, a DTC will be stored in the memory, and the SRS indicator may come on depending on the malfunction detected.

Note. Check the condition of the battery (see BATTERY TEST ), and the charging system (see ALTERNATOR AND REGULATOR CIRCUIT TROUBLESHOOTING ). Low battery voltage may cause some intermittent failures. A faulty or damaged cable reel can cause intermittent problems related to the driver's airbag inflator DTCs.

After checking the DTC, troubleshoot as follows

  1. Check for DTCs with the HDS (see «How to Read DTCs»(/acura/zdx/i-2009-2013/remont/airbag/#srs-supplemental-restraint-system__how-to-read-dtcs) ).
  2. Clear the DTCs with the HDS (see «How to Clear DTCs»(/acura/zdx/i-2009-2013/remont/airbag/#srs-supplemental-restraint-system__how-to-clear-dtcs) ).
  3. Set the parking brake, then start the engine, and let it idle.
  4. The SRS indicator comes on for about 6 seconds and then goes off.
  5. Shake the related wire harnesses and the connectors, and look for loose connections, poor pin fits, and poor grounds.
  6. Take a test-drive (quick acceleration, quick braking, and cornering), turn the steering wheel fully left and right, and hold it there for 5 to 10 seconds. If the problem recurs, the SRS indicator will come on.
  7. If you cannot duplicate the concern, ask the client about the conditions when it occurred, or ask the client to demonstrate the concern.
  8. If you cannot duplicate the intermittent failure, the system is OK at this time.

SRS Unit Update

Special Tools Required

  1. Honda Diagnostic System (HDS) tablet tester
  2. Honda Interface Module (HIM) and an iN workstation with the latest HDS software version
  3. HDS pocket tester
  4. GNA600 and an iN workstation with the latest HDS software version
  5. MVCI unit with the latest control module (CM) update software installed

Any one of the above updating tools can be used.

Note. Make sure the HDS/iN workstation or the MVCI unit has the latest HDS software version. Before you update the SRS unit, make sure the battery in the vehicle is fully charged. Never turn the ignition switch to ACCESSORY (I) or LOCK (0), or never press the engine start/stop button to select the OFF or ACC mode during the update. If there is a problem with the update, leave the ignition switch ON (II) or vehicle in the ON mode. To prevent SRS unit damage, do not operate anything electrical (headlights, audio system, brakes, A/C, power windows, panoramic glass roof (if equipped), door locks, etc.) during the update. To ensure the latest program is installed, do an SRS unit update whenever the SRS unit is substituted or replaced. You cannot update an SRS unit with the program it already has. It will only accept a new program. If you need to diagnose the HIM because the HIM's red (#3) light came on or was flashing during the update, leave the ignition switch in ON (II) or keep the vehicle in the ON mode when you disconnect the HIM from the data link connector (DLC). This will prevent SRS unit damage.

Airbags

The SRS is a safety device which, when used with the front seat belts, is designed to help protect the driver and front passenger in a frontal impact exceeding a certain set limit. The system consists of the SRS unit (A) including safing sensor and impact sensor, the cable reel (B), the driver's airbag (C), the front passenger's airbag (D), the side airbags (E), the side curtain airbags (F), the front seat belt tensioners (G), the side impact sensors (first) (H), the front impact sensors (I), the rear safing sensor (J), and the side impact sensors (second) (K).

Since the driver's and the front passenger's airbags use the same sensors, both normally inflate at the same time. However, it is possible for only one airbag to inflate. This can occur when collision severity is near threshold for airbag deployment. In such case, the SRS will only deploy airbags when the protection provided by the front seat belt is insufficient.

Front Passenger's Weight Sensors

The front passenger's weight sensors (L) are part of the front passenger's seat base. The front passenger's weight sensors detect the weight on the seat, and send the information to the ODS unit (M). If the total weight is about 30 kg (66 lbs) or less, the ODS unit sends a signal to the SRS unit to prevent the front passenger's airbag from deploying. When the front passenger's airbag is disabled, the passenger airbag cutoff indicator (N) on the center panel comes on to alert the driver that the front passenger's airbag will not deploy in a front-end collision.

Note. The sensors only detect the weight on the seat. The sensors do not detect the weight of the passenger's legs or arms that may be resting on the floor or armrests.

Driver's Seat Position Sensor

The driver's seat position sensor (0) is under the driver's seat on the left side. When the driver's seat is moved to the forward most position, the deployment of the driver's airbag is moderated to decrease its force of impact during a front-end collision.

Scheme 44

Scheme 44: Driver's Seat Position Sensor

Rear Safing Sensor

The rear safing sensor is located under the second row seat. The rear safing sensor performs the same basic function as the safing sensor in the SRS unit. It measures sideways G force, such as the force the vehicle would receive in a side collision in the rear, and sends that information to the SRS unit. The SRS unit uses that information, and the information from the side impact sensors to determine the side that is impacted and the force. If the threshold is met, the SRS unit deploys the side airbag, the side curtain airbag, and the front seat belt tensioner on that side.

Side Airbag Cutoff Indicator/OPDS Operation

The OPDS sensors (P) are located on the front passenger's seat- back foam pad. The ODS unit detects front passenger's position on the seat by using the OPDS sensors, then sends the signals to the SRS unit. The indicator comes on when the front passenger's seat is occupied by a small adult or child who is leaning into the deployment path, or when an object (grocery bag, briefcase, purse, etc.) is in the seat. This indicates the front passenger's side airbag is off and will not deploy; there is no problem with the side airbag. If the passenger sits upright or moves to another seat, or you remove the object from the seat, the indicator should go off. There will be some delay between the occupant's repositioning, and when the indicator will turn on or off.

Passenger's Airbag Cutoff Indicator/Front Passenger's Weight Sensor Operation

The indicator comes on if the weight of the front passenger is about 30 kg (66 lbs) or less. This indicates the front passenger's airbag is off and will not deploy. The front airbag is shut off to reduce the chance of airbag-caused injuries.

SRS Operation

The main circuit in the SRS unit senses and analyzes the force of impact and, if necessary, ignites the inflator charges. If battery voltage is too low or power is disconnected due to the impact, the voltage regulator and the back-up power circuit will keep voltage at a constant level.

Front Seat Belt Tensioners

  1. The front impact sensor, the side impact sensor, or the rear safing sensor must activate and send electric signals to the microprocessor.
  2. The microprocessor must compute the signals and trigger the tensioners.
  3. The charges must ignite and deploy the tensioners.

Driver's and Front Passenger's Airbag(s)

  1. The front impact sensor must activate and send electric signals to the microprocessor.
  2. The microprocessor must compute the signals and trigger the front airbag inflators.
  3. The triggered inflators must ignite and deploy the front airbags.

Side Airbag(s)

  1. The side impact sensor must activate and send electric signals to the microprocessor.
  2. The microprocessor must compute the signals and trigger the side airbag inflators. However, the microprocessor does not trigger the front passenger's side airbag if the SRS unit determines that the front passenger's head is in the deployment path of the side airbag.
  3. The triggered inflators must ignite and deploy the side airbags.

Scheme 45

Scheme 45: Side Curtain Airbag(s)
  1. The side impact sensor or the rear safing sensor must activate and send electrical signals to the microprocessor.
  2. The microprocessor must compute the signals and trigger the side curtain airbag and the side airbag inflators.
  3. The triggered inflators must ignite and deploy the side curtain airbag and the side airbag at the same time.

Self-Diagnostic System

A self-diagnostic circuit is built into the SRS unit; when the ignition switch is turned to ON (II), or press the engine start/stop button to select the ON mode, the SRS indicator comes on and goes off after about 6 seconds if the system is operating normally. If the indicator does not come on, or does not go off after 6 seconds, or comes on while driving, it indicates an abnormality in the system. The system must be inspected and repaired as soon as possible.

For better serviceability, the SRS unit memory stores any DTCs related to the cause of the malfunction. The SRS unit is connected to the data link connector (DLC). This information can be read with the HDS when it is connected to the DLC (see DTC (DIAGNOSTIC TROUBLE CODES) ).

Note. Before you disconnect the negative cable from the battery for troubleshooting, refer to Battery Terminal Disconnection and Reconnection (see BATTERY TERMINAL DISCONNECTION AND RECONNECTION ).

E-Pretensioner

When at a risk of a collision, the E-pretensioner system, working with the collision mitigation braking system (CMBS), retracts the driver's and front passenger's seat belt several times slightly to provide a tactile warning to the driver. And when a collision is imminent, the E-pretensioner system retracts the seat belt tightly to help reduce injury from the impact. The E-pretensioner system also works when the driver brakes hard and the brake assist system is turned on.

CMBS and E-Pretensioner Operation

Approaching a vehicle ahead: When driving, the millimeter wave radar detects a vehicle ahead, and the system provides audible and visual warnings if it detects a risk of collision.

Scheme 46

Scheme 46: CMBS and E-Pretensioner Operation

Closing on a vehicle ahead: The system applies light braking, and increases seat belt tension slightly to provide a tactile warning to the driver. The front passenger does not feel the tactile warning.

Scheme 47

Scheme 47

Collision unavoidable: The system activates strong braking, and securely tightens both the driver's and front passenger's seat belts to help reduce injury caused by the impact.

Scheme 48

Scheme 48

The mechanical portion of the E-pretensioner consists of the motor and the gear sections. The collision mitigation braking system and the brake assist system sends signals to the motor in the retractor to retractor rewind the belt. If the system judges that the driving situation is safe, the tension on the seat belts is released. The E-pretensioners used in conjunction with the conventional tensioners.

Scheme 49

Scheme 49: E-Pretensioner

E-Pretensioner Unit

The E-pretensioner unit operates the motor-driving controls based on F-CAN data it receives from the ACC unit, VSA modulator-control unit, and the PCM. Also the E-pretensioner unit receives seat belt buckle switch signals from the SRS unit by an interactive communication function. The E-pretensioner unit has a self-diagnostic function, and if it detects a malfunction, it sends its information to the SRS unit. The SRS indicator is then turned on by the SRS unit.

Airbag and Tensioner Disposal

Special Tools Required

Deployment Tool 07AAZ-000A100

Before scrapping any front airbags, side airbags, side curtain airbags, or front seat belt tensioners (including those in a whole vehicle to be scrapped), the part(s) must be deployed. If the vehicle is still within the warranty period, the Acura District Parts and Service Manager must give approval and/or special instruction before deploying the part(s). Only after the part(s) have been deployed (as the result of vehicle collision, for example), can they be scrapped. If the parts appear intact (not deployed), treat them with extreme caution. Follow this procedure.

Deploying Airbags in the Vehicle

If an SRS equipped vehicle is to be entirely scrapped, its front airbags, side airbags, side curtain airbags, and front seat belt tensioners should be deployed while still in the vehicle. These parts should not be considered as salvageable parts and should never be installed in another vehicle.

NOTE: Place the deployment tool at least 10 m (33 ft) away from the vehicle. The driver's and front passenger's airbags have dual inflators. Twist each pair of unlike colored wires together, and clip an alligator clip to each pair.
  13. Connect a 12 volt battery to the tool. If the green light on the tool comes on, the igniter circuit is defective and cannot deploy the component. Go to «DISPOSAL OF DAMAGED COMPONENTS»(/acura/zdx/i-2009-2013/remont/airbag/#srs-supplemental-restraint-system__disposal-of-damaged-components) . If the red light on the tool comes on, the component is ready to be deployed.
  14. Push the tool's deployment switch. The airbags and tensioners should deploy (deployment is both highly audible and visible: A loud noise and rapid inflation of the bag, followed by slow deflation). If the components deploy and the green light on the tool comes on, continue with this procedure. If a component does not deploy, and the green light comes on, its igniter is defective. Go to «DISPOSAL OF DAMAGED COMPONENTS»(/acura/zdx/i-2009-2013/remont/airbag/#srs-supplemental-restraint-system__disposal-of-damaged-components) . During deployment, the airbags can become hot enough to burn you. Wait for 30 minutes after deployment before touching the airbags.
