SRS Light Illuminated
If you receive customer reports in the above model vehicles of the SRS light being illuminated accompanied by either of the diagnostic fault codes listed below, perform the following repair procedure.
Note:
Replacement of the contact spiral is not necessary for this repair procedure. Returned contact spirals will be subject to testing and may be debited if found to be operational.
Fault Codes:
DTC 9200 - the resistance value in the ignition circuit containing component R12/13 is too high
DTC 9210 - the resistance value in the ignition circuit containing component R12/14 is too high
Note:
Short test printout from STAR Diagnosis required to be sent with returned connectors.
1. Fully extend the steering wheel.
2. Remove the steering column module (SCM). Refer to WIS document AR54.25-P-2802GZ (164) or AR54.25-P-2802RT (251)
Note:
The battery ground cable must be disconnected. If this step is omitted, other faults may be introduced into the vehicle when cutting the SCM harness.
3. Remove the (SCM) connector from the jacket tube (Figure 1).
4. Remove the cover for the instrument panel. Refer to WIS document AR68.10-P-1060GZ (164) or AR68.10-P-0160RT (251).
5. Remove the radio (COMAND). Refer to WIS document AR82.60-P-7502GZ (164) or AR82.60-P-7502RT (251).
6. Unclip the cable anchor and pull out the harness (Figure 2).
7. Remove the fabric tape at both ends of the black harness conduit.
8. The wire colors for ignition circuit 1 and 2 are the same and cannot be interchanged. Ignition circuit 1 connects to terminals 5 and 6. Terminals 5 and 6 of the repair harness are marked with a tag, see Figure 3.
9. Temporarily tie the repair harness loosely to the SCM harness using a cable tie (Figure 4). This will help to keep track of the wires so they do not get interchanged.
10. Cutting Procedure, First Time Repair: Cut the 0.50 mm sq. wires of the vehicle harness connected to ignition circuit 1, Airbag pin 5 (0.5 BUBK) and pin 6 (0.5 BKYE) at the SCM connector plug and pull them out of the conduit.
11. Cutting Procedure, Previous Repair: If the SCM connector has been previously repaired using individual repair wires as described in DTB T-B 91.60/93d, remove the insulating tape from the repaired harness. Locate the blue-black wire (0.5 BUBK) connected to pin 5 and the black-yellow wire (0.5 BKYE) connected to pin 6 of the SCM connector.
12. Cut the wires so the white pigtail and solder connector are completely removed. The new repair harness needs to be spliced directly to the vehicle harness using new solder connectors.
13. Slip solder connector (A002 546 13 41) onto the cut wires. Strip approximately 15 mm of insulation from the repair harness wires and the vehicle SCM harness wires. Braid the 15 mm stripped ends of the repair wires and SCM harness wires (Figure 5).
14. Solder the two airbag wires, pins 5 and 6 in accordance with the specified repair method in WIS document AR54.18-P-0100-6A (Figure 6).
Note:
After splicing the repaired harness will be longer than the original harness.
15. Cut remaining wires of the vehicle harness as described in step 10, or 11 and 12. Slip solder connector (A002 546 13 41) onto the wires listed below. Strip 15 mm of insulation from the ends of both wires and braid together (Figure 5). Solder in accordance with the specified repair method in WIS document AR54.18-P-0100-06A (Figure 6).
Terminal 3 Blue-Black (0.5 BUBK)
Terminal 4 Black-Yellow (0.5 BKYE)
Terminal 8 Brown (0.5 BN)
Terminal 9 Red-Blue (0.5 RDBU)
Terminal 10 Green-White (0.5 GNWH)
Terminal 11 Green (0.5 GN)
16. If vehicle is equipped with a steering wheel heater slip solder connector (A002 546 1441) onto the wires listed below. Strip 15 mm of insulation from the ends of both wires and braid together (Figure 5). Solder in accordance with the specified repair method in WIS document AR54.18-P-0100-06A (Figure 6). If there is no steering wheel heater, tape up the unused wires of the repair harness.
Terminal 1 Brown (0.75 BN)
Terminal 2 Violet-Black (1.0 VTBK)
Note:
Ensure during the reassembly of the SCM connector that all terminals are reinstalled in their correct positions. Use the appropriate WEB ETM document to confirm pin locations and wire colors.
17. Insulate the solder connectors and the repaired harness with fabric tape. The repaired harness will be longer than the original harness.
18. Route the harness out towards the SCM. Install the SCM connector onto the jacket tube and reinstall the cable anchor (Figure 7).
19. Form a loop in the excess harness and tie it to the existing harness with a cable tie (Figure 8).
20. Reassemble the vehicle in the reverse order.
Note:
Replacement of the contact spiral is not necessary. The mounting bolt for the steering wheel must always be replaced.
Note:
Return cut off connectors to the QEC along with Short Test print out from STAR Diagnosis for analysis. Claims submitted as of repair date June 13, 2007 without returned parts and printouts may be debited.
