Acura RL. Manual - part 153

1. Clear the DTC memory (see CLEAR THE DTC MEMORY WITH THE HDS ).

2. Turn the ignition switch ON (II), and check that the SRS indicator comes on for about 6 seconds and

then goes off.

Does the SRS indicator stay on, and is DTC 51-xx, 52-xx, 53-xx, 54-xx, or 55-xx indicated?

YES - Replace the SRS unit (see SRS UNIT REPLACEMENT ).

NO - Intermittent failure, the system is OK at this time. Go to TROUBLESHOOTING
INTERMITTENT FAILURES . If another DTC is indicated, troubleshoot the DTC.

DTC EX-XX ("X" CAN BE 0 THRU 9 OR A THRU F): CONTROL OPERATION RECORDED;
DTC FX-XX ("X" CAN BE 0 THRU 9 OR A THRU F): AIRBAGS AND/OR TENSIONERS
DEPLOYMENT RECORDED

The SRS unit must be replaced after any airbags and/or tensioners have deployed (see COMPONENT
REPLACEMENT/INSPECTION AFTER DEPLOYMENT ).

voltage. If the voltage is low, replace the battery or repair the charging
system before troubleshooting the SRS. If the battery/system voltage is
now OK, ask the client if the battery ever went dead. A dead battery
may trigger one of these DTCs.



Before doing this troubleshooting procedure, review SRS Precautions
and Procedures (see PRECAUTIONS AND PROCEDURES ) and General
Troubleshooting Information (see GENERAL TROUBLESHOOTING
INFORMATION ).

NOTE:



DTC E2-11: Front passenger's airbag does not deploy by SWS
operation.



DTC E4-11: Front left side airbag does not deploy by OPDS operation.



DTC F1-11: Driver's airbag and/or driver's seat belt tensioner deployed.



DTC F2-11: Front passenger's airbag and/or front passenger's seat belt
tensioner deployed.



DTC F3-11: Driver's side airbag, left side curtain airbag, and/or driver's
seat belt tensioner deployed.



DTC F4-11: Front passenger's side airbag, right side curtain airbag,
and/or front passenger's seat belt tensioner deployed.

NOTE:



DTC E2-11 is set if the system triggered airbag deployment but the front
passenger's airbag was prevented from deploying because of the front
passenger's weight sensor.



DTC E4-11 is set if the system triggered a passenger's side airbag
deployment but the airbag was prevented from deploying by the OPDS.

DTC 61-1X ("X" CAN BE 0 THRU 9 OR A THRU F): OPEN IN DRIVER'S SEAT BELT BUCKLE
SWITCH

1. Clear the DTC memory (see CLEAR THE DTC MEMORY WITH THE HDS ).

2. Turn the ignition switch ON (II), then buckle and unbuckle the left side seat belt several times.

3. Read the DTC (see GENERAL TROUBLESHOOTING INFORMATION ).

Is DTC 61-1x indicated?

YES - Go to step 4.

NO - Intermittent failure, the system is OK at this time. Go to TROUBLESHOOTING
INTERMITTENT FAILURES . If another DTC is indicated, troubleshoot the DTC.

4. Turn the ignition switch OFF.

5. Disconnect the left side wire harness or the driver's seat wire harness 3P connector from the driver's

seat belt buckle switch 3P connector (A).

6. Buckle the driver's seat belt.



Measure the resistance between the No. 1 and No. 3 terminals of the left side seat belt buckle
switch 3P connector. There should be 0-1 ohms.



Measure the resistance between the No. 2 and No. 3 terminals of the same connector. There
should be an open circuit or at least 1Mohms.

Replace the right side impact sensor (first) (see SIDE IMPACT SENSOR
(FIRST) REPLACEMENT ).

NOTE:

Before doing this troubleshooting procedure, review SRS Precautions and
Procedures (see PRECAUTIONS AND PROCEDURES ) and General
Troubleshooting Information (see GENERAL TROUBLESHOOTING
INFORMATION ).

Are the resistances as specified?

YES - Go to step 7.

NO - Replace the driver's seat belt buckle assembly (see SEAT BELT BUCKLE ), then clear the
DTC.

7. Unbuckle the driver's seat belt.



Measure the resistance between the No. 2 and No. 3 terminals of the driver's seat belt buckle
switch 3P connector. There should be 0-1 ohms.



Measure the resistance between the No. 1 and No. 3 terminals of the same connector. There
should be an open circuit or at least 1 M ohms.

NO - Replace the driver's seat belt buckle assembly (see SEAT BELT BUCKLE ), then clear the
DTC.

8. Measure the resistance between the No. 3 terminal of the driver's seat wire harness 3P connector and

body ground. There should be 0-1 ohms.

Is the resistance as specified?

YES - Go to step 9.

NO - Open in the driver's seat wire harness or left side wire harness, or poor ground connection at
G601 (see LEFT SIDE WIRE HARNESS (FRONT BRANCH) ). If G601 is OK, replace the faulty
harness.

9. Disconnect the negative cable from the battery, then wait for 3 minutes.

10. Disconnect both seat belt tensioner 4P connectors from the left side wire harness and right side wire

harness (see step 6 ).

11. Disconnect SRS unit connector B (28P) from the SRS unit (see step 7 ).

12. Measure the resistance between the No. 12 terminal of SRS unit connector B (28P) and the No. 1

terminal of the driver's seat wire harness 3P connector. There should be 0-1 ohms.
