Reopening the SRS Unit Circuit For Diagnosis

Special Tools Required

SRS short canceller 070AZ-SAA0100

Note. To prevent damaging the connector cavity, insert the SRS short canceller straight into the cavity from the terminal side. Before installing the short canceller, wash it with electrical contact cleaner, then dry it with compressed air. Do not use the special tool if it is damaged. Make sure to remove the special tool before reconnecting.

When SRS unit connectors A, B, or C are disconnected, a short circuit is created in the connector by its own function to prevent an airbag deployment. The circuit may need to be opened when diagnosis is done on the system. Insert the short canceller (No. 070AZ-SAA0100) in the specified cavities when it is necessary to keep the circuit open for diagnosis.

DTC (Diagnostic Trouble Codes)

The self-diagnostic function of the SRS system allows it to locate the causes of system problems and then 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 ON (II), the SRS indicator comes on. If it goes off after 6 seconds, the system is normal, and is not currently detecting any abnormality.
  2. If there is an abnormality, the system locates and defines the problem, stores this information in memory, and turns the SRS indicator on. The data remains in the memory even when the ignition switch is turned off or if the battery is disconnected.
  3. The data is stored in memory as a diagnostic trouble code (DTC).
  4. The "x" at the end of each DTC denotes a numeric character (0 thru 9) or an alpha character (A thru F) that is display on the HDS.
  5. 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 ON 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.
  6. When you connect the HDS to the data link connector (DLC), you can retrieve a more detailed DTC in the Honda Systems "SRS" menu.
  7. After reading and recording the DTC, proceed with the troubleshooting procedure for that code.

Precautions

  1. Use only a digital multimeter to check the system. If it's not a Honda multimeter, 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.
  2. Whenever the ignition switch is ON (II), or has been turned OFF for less than 3 minutes, be careful not to bump the SRS unit; the airbags could accidentally deploy and cause damage or injuries.
  3. Before you remove the dashboard wire harness, floor wire harness, or the side curtain 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.
  4. Make sure the battery is fully charged. If the battery is dead or low, measuring values won't be correct.
  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 HDS. Backprobe spring-loaded lock type connectors correctly.

  9. Turn the ignition switch ON (II) again. If the SRS indicator comes on for 6 seconds, and then goes off, the system is OK.

Troubleshooting Intermittent Failures

If there was a malfunction, but it does not recur, it will be stored in the memory as an intermittent failure, and the SRS indicator may come on depending on this 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.

After checking the DTC, troubleshoot as follows

  1. Make sure the ignition switch is OFF.
  2. Connect the HDS to the data link connector (DLC) (A).
  3. Turn the ignition switch ON (II).
  4. Make sure the HDS communicates with the vehicle and the SRS unit.

  3. Connect the HDS to the data link connector (DLC) (A).
  4. Turn the ignition switch ON (II).
  5. Make sure the HDS communicates with the vehicle and the SRS unit. If it does not communicate, troubleshoot the DLC circuit: '04-06 models (see «DLC CIRCUIT TROUBLESHOOTING»(/acura/tsx/i-2003-2008/remont/testing-diagnostics/#pgm-fi-system__dlc-circuit-troubleshooting) ) '07-08 models (see «'07-08 MODELS»(/acura/tsx/i-2003-2008/remont/testing-diagnostics/#pgm-fi-system) )
  6. From the HDS Main Menu, select SRS, then Parameter Information, then Buckle Switch, Seat Position Sensor.
  7. Using a piece of tape (A), mark the location on the seat's outer cover (B) where the front riser cover meets the seat riser (C). The driver's seat position sensor should read "NEAR."
  8. Move the seat back in small increments (about 0.2 in., 5 mm) until the driver's seat position sensor reads "NOT NEAR." The seat should be about 1 in. (25 mm) from the front. NOTE: It takes a few seconds for the HDS to display changes, so wait about 5 seconds between each move. If the driver's seat position sensor data does not work as described above, check the driver's seat position sensor or the cover plate for damage, and replace parts as needed.
  9. Turn the ignition switch OFF, and disconnect the HDS from the DLC.

SYMPTOM TROUBLESHOOTING CHART

Airbags

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), front impact sensors (H), side impact sensors (first) (I) and side impact sensors (second) (J).

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 the severity of a collision is at the margin, or threshold, that the SRS unit determines whether or not the airbags will deploy. In such cases, the seat belt will provide sufficient protection, and the supplemental protection offered by the airbag would be minimal.

Front Passenger's Weight Sensors ('06-08 models)

The front passenger's weight sensors (K) are part of the seat base. The weight sensors detect the weight on the seat, and send the information to the ODS unit. 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 on the center panel comes on to alert the driver that the front passenger's airbag will not deploy in a front-end collision.

Driver's Seat Position Sensor ('06-08 models)

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

OPDS/ODS

The side airbag system also includes an occupant position detection system (OPDS). This system consists of sensors (M) and a OPDS/ODS unit (N) in the front passenger's seat-back. The OPDS/ODS unit sends occupant height and position data to the SRS unit. If the OPDS/ODS unit determines that the front passenger is of small stature (for example, a child) or the front passenger is leaning into the side airbag deployment path, the SRS unit will automatically disable the passenger's side airbag. The SRS unit will also disable the airbag when the OPDS detects certain objects on the seat. When the side airbag is disabled, the side airbag cutoff indicator on the instrument panel alerts the driver that the passenger's side airbag will not deploy in a side impact. When the object is removed, or the passenger sits upright, the side airbag cutoff indicator will go off after a few seconds, alerting the driver that the passenger's side airbag will deploy in a side impact.

Side Airbag Cutoff Indicator/OPDS/ODS Operation

The indicator comes on if the front passenger's seat is occupied by a small adult or child who is leaning into the deployment path, or 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 light should go off. There will be some delay between the occupant's repositioning and when the indicator will turn on or off.

Passenger Airbag Cutoff Indicator ('06-08 models)

The indicator comes on if the weight of the front passenger 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 judges 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, respectively, will keep voltage at a constant level.

For the SRS to operate

Seat Belt Tensioners

  1. A front impact sensor must activate and send electric signals to the microprocessor.
  2. The microprocessor must compute the signals and send them to the tensioners.
  3. The charges must ignite and deploy the tensioners.

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

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

Side Airbag(s)

  1. Aside impact sensor must activate and send electric signals to the microprocessor.
  2. The microprocessor must compute the signals and send them to the side airbag inflator(s). However, the microprocessor cuts off the signals to 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 inflator that receives the signal must ignite and deploy the side airbag.

Side Curtain Airbag(s)

  1. Side impact sensors must activate and send electrical signals to the microprocessor.
  2. The microprocessor must compute the signals and send them to the side curtain airbag and side airbag inflator(s).
  3. The inflator that receives the signals must ignite and deploy the side curtain airbag and side airbag at the same time.

Scheme 44

Self-diagnostic System

A self-diagnostic circuit is built into the SRS unit; when the ignition switch is turned ON (II), 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 if it 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 a DTC that relates 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 DTC (DIAGNOSTIC TROUBLE CODES) ).

Note. Before you disconnect the negative cable from the battery for troubleshooting, make sure you have the anti-theft code for the audio system and the navigation system (if equipped).

SRS indicator stays on, but no DTCs are stored

Note. If you cannot retrieve DTCs with the HDS using the SRS menu method, retrieve flash codes with the HDS in SCS mode. A new SRS unit must sense the entire system is OK before completing its initial self-test. The most common cause of an incomplete self-test is the failure to replace all deployed parts after a collision, in particular seat belt tensioners (see COMPONENT REPLACEMENT/INSPECTION AFTER DEPLOYMENT ). A battery/system voltage above 15.2 V can cause the SRS indicator to come on without storing any DTCs.

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.

  1. Turn the ignition switch OFF, then disconnect the negative cable from the battery, then wait for 3 minutes before starting work.
  2. Confirm that each airbag, side airbag, side curtain airbags, or seat belt tensioner is securely mounted.
  3. Confirm that the deployment tool is functioning properly by following the check procedure on the tool label. Driver's Airbag
  4. Remove the access panel (A) from the steering wheel then disconnect the driver's airbag 4P connector (B) from the cable reel. Front Passenger's Airbag
  5. Remove the glove box, then disconnect the front passenger's airbag 4P connector (A) from the dashboard wire harness. Side Airbag
  6. Disconnect the side airbag 2P connector (A) from the floor wire harness. Side Curtain Airbag
  7. Disconnect the side curtain airbag harness 2P connector (A) from the side curtain airbag. Seat Belt Tensioner
  8. Disconnect the floor wire harness 4P connector (A) from the seat belt tensioner. Pull the seat belt out all the way and cut it.
  9. Cut off each connector, strip the ends of the wires. Twist each pair of unlike colored wires together, and clip an alligator clips (A) to each pair. Place the deployment tool at least 30 feet (10 meters) away from the vehicle. NOTE: The driver's and front passenger's airbags have dual inflators. The like colored wires go to the individual inflators.
  10. Connect a 12 volt battery to the deployment 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/tsx/i-2003-2008/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.
  11. 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/tsx/i-2003-2008/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.
  12. Dispose of the complete airbag. No part of it can be reused. Place it in a sturdy plastic bag (A), and seal it securely. Dispose of the deployed airbag according to your local regulations.

Deploying Components Out of the Vehicle

If an intact airbag or tensioner has been removed from a scrapped vehicle, or has been found defective or damaged during transit, storage, or service, it should be deployed as follows

Scheme 314

Scheme 314: Deploying Components Out of the Vehicle
Scheme 314: Deploying Components Out of the Vehicle
  1. Confirm that the deployment tool is functioning properly by following the check procedure on the tool label.
  2. Position the airbag face up, outdoors, on flat ground, at least 30 feet (10 meters) from any obstacles or people.

Disposal of Damaged Components

  1. If installed in a vehicle, follow the removal procedure for the driver's airbag (see «DRIVER'S AIRBAG REPLACEMENT»(/acura/tsx/i-2003-2008/remont/airbag/#srs-supplemental-restraint-system) ), front passenger's airbag (see «FRONT PASSENGER'S AIRBAG REPLACEMENT»(/acura/tsx/i-2003-2008/remont/airbag/#srs-supplemental-restraint-system__front-passengers-airbag-replacement) ), side airbag (see «SIDE AIRBAG REPLACEMENT»(/acura/tsx/i-2003-2008/remont/airbag/#srs-supplemental-restraint-system__side-airbag-replacement) ), side curtain airbag (see «SIDE CURTAIN AIRBAG REPLACEMENT»(/acura/tsx/i-2003-2008/remont/airbag/#srs-supplemental-restraint-system) ), and seat belt tensioner (see «FRONT SEAT BELT REPLACEMENT»(/acura/tsx/i-2003-2008/remont/restraints-control-systems/#seat-belt-system__front-seat-belt-replacement) ).
  2. In all cases, make a short circuit by cutting, stripping, and twisting together the two inflator wires. NOTE: The driver's and front passenger's airbags have dual inflators. The like colored wires go to the individual inflators.
  3. Package the component in exactly the same packaging that the new replacement part came in.
  4. Mark the outside of the box "DAMAGED AIRBAG NOT DEPLOYED," "DAMAGED SIDE AIRBAG NOT DEPLOYED," "DAMAGED SIDE CURTAIN AIRBAG NOT DEPLOYED," and "DAMAGED SEAT BELT TENSIONER NOT DEPLOYED," so it does not get confused with your parts stock.
  5. Contact your Acura District Parts and Service Manager for how and where to return it for disposal.

Deployment Tool Check

  1. Connect the yellow clips to both switch protector handles on the tool.
  2. Then connect the red lead to the positive battery post and the black lead to the negative battery post.
  3. Push the operation switch: The green light should come on, indicating that the tool is operating properly and is ready for use. If the red light stays on, the tool is faulty, and another one must be used for the procedure.
