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 via a 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 memory, and turns on the SRS indicator The data remains in 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
  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), press the engine start/stop button 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 SRS floor wire harness, disconnect the driver's airbag connector, the front passenger's airbag connector, both side airbag connectors, both side curtain airbag connectors, and both 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 backprobe set and the multimeter Backprobe spring-loaded lock type connectors correctly

The SRS is a safety device which, when used with the seat belt, 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, including safing sensor and impact sensor (A), the cable reel (B), the driver's airbag (C), the front passenger's airbag (D), side airbags (E), side curtain airbags (F), seat belt tensioners (G), side impact sensors (first) (H), front impact sensors (I), rear safing sensor (J), and side impact sensors (second) (K)

Since the driver's and 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 the threshold for airbag deployment In such case, the SRS system will only deploy airbags when the protection provided by the seat belt is insufficient

Front Passenger's Weight Sensors

The front passenger's weight sensors (L) are part of the front passenger's seat 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 65 lbs (30 kg) or less, the ODS unit sends a signal to the SRS unit to prevent the passenger's airbag from deploying When the 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 (O) is under the driver's seat on the left side When the driver's seat is moved all the way forward, the deployment of the driver's airbag is moderated to decrease its force of impact during a front-end collision

Scheme 42

Scheme 42: Driver's Seat Position Sensor

Rear Sating Sensor

The rear safing sensor is located under the rear seat cushion 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 second 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 seat belt tensioner on that side

Side Airbag Cutoff Indicator/OPDS Operation

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 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/Seat Weight Sensor Operation

The indicator comes on if the weight on the front passenger's seat is about 65 lbs (30 kg) or less This indicates the passenger's front 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

Seat Belt Tensioners

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

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

  1. (1) A front impact sensor must activate and send electric signals to the microprocessor
  2. (2) The microprocessor must compute the signals and trigger the airbag inflator(s)
  3. (3) The triggered inflators that received signals must ignite and deploy the airbags

Side Airbag(s)

  1. (1) Aside impact sensor must activate and send electric signals to the microprocessor
  2. (2) The microprocessor must compute the signals and trigger the side airbag inflator(s) 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. (3) The triggered inflators the signal must ignite and deploy the side airbags

Side Curtain Airbag(s)

  1. (1) Aside impact sensor or the real safing sensor must activate and send electrical signals to the microprocessor
  2. (2) The microprocessor must compute the signals and trigger the side curtain airbag and side airbag inflator(s)
  3. (3) The triggered inflators that must ignite and deploy the side curtain airbag and 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 the engine start/stop button is pressed 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 a problem 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, and the 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 GENERAL TROUBLESHOOTING INFORMATION )

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

Airbag and Tensioner Disposal

Special Tools Required

Deployment tool 07HAZ-SG00500

Before scrapping any airbags, side airbags, side curtain airbags, or 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 airbags, side airbags, side curtain airbags, and 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
