Traction Control - Steering Angle Harness Modification

BULLETIN NUMBER:
P-Si-54.18/52

GROUP:
54

DATE:
February 2000

SUBJECT:
STEERING ANGLE HARNESS MODIFICATION

MODELS:
215/220

SYMPTOM
"Traction control malfunction" is displayed in the instrument cluster (DTC 1140 and 1504 are stored in the ESP/SPS/BAS control module [N47-5]).

POSSIBLE CAUSE
Low battery voltage (battery voltage dropping below 50%) at the steering column module (N80) Steering angle sensor initialization lost because of low voltage.

CORRECTIVE ACTION
Install direct voltage line to the steering angle sensor.

Effective Serial Number Range:

PROCEDURE

Figure 2:

1. Disconnect and cover the negative battery terminal.

2. Remove left front door threshold, left kick panel and pull back rug.

3. Open harness tray and disconnect connector X18 (white 14-pin connector [arrow, Figure 1]) located in the left front footwell near doorsill.

Figure 1:

4. Cut wire (2, Figure 2 [on female side of connector]), socket position 12 (circuit 30Z), into two sections (approx. 3" from connector) and strip off approx. 15 mm (1/2") of insulation off each wire end.

5. Splice an auxiliary wire (in parallel) to the two ends of the wire cut in step 4 (magnification, Figure 2).

- Cut (approx.) a 5' 3" section of 18 gauge (AWG) wire (1, Figure 2).

- Strip off approx. 0.15 mm (0.5") of insulation.

- Splice all three wires together using an approved wire splice.

Note:
Refer to S.I 54/76 (May 1996) for proper method of splicing and connecting wires in a wire harness. Ensure wire splice has a loop for strain relief and is covered with premium quality electrical tape (e.g. 3M Scotch 33 [R]) which is resistant to heat.

Figure 3:

6. Route auxiliary cable to fuse and relay box, located in engine compartment (Figure 3), along existing wire harness and wire harness tray, secure wire with cable ties as necessary.

7. Disconnect fuse carrier (red [position 2]), which is connected to red/yellow wire, from fuse box

Figure 4:

8. Remove fuse 25 (arrow, Figure 4).

Figure 5:

9. Remove fuse connector (using suitable tool from the contact removal kit [963 589 00 33 00J) along with red/yellow wire from fuse carrier (left arrow, Figure 5).

10. Cut off fuse connector from end of wire.

Figure 6:

11. Connect red/yellow wire (removed from fuse carrier) to auxiliary wire (right arrow, Figure 5), which was spliced into circuit 30Z (step 5), using approved splicing method (magnification, Figure 6). Secure wire splice to harness using cable ties.

Note:
Refer to S.I. 54/76 (May 1996) for proper method of splicing and connecting wires in a wire harness. Ensure wire splice has loop for strain relief and is covered with premium quality electrical tape (e.g. 3M Scotch 33 [R]) which is resistant to heat.

12. Reinstall fuse carrier (left arrow, Figure 5) back into fuse box.

13. Reassemble in reverse order, reconnect battery negative terminal (refer to WIS or SMS; Grp. 54.10; job no. AR54.10-P-0003; for proper initialization of electrical systems after reconnection of battery).

14. Erase all DTC's using StarDiagnosis (DAS) and road test vehicle.
