WIRING DIAGRAM
INSPECTION PROCEDURE
| 1.CHECK DTC (BRAKE CONTROL SYSTEM) |
Check that the steering sensor DTC (brake control system DTC) is not output.
- Result:
| Result | Proceed to |
| DTC (C1231/31) is not output | A |
| DTC (C1231/31) is output | B
|
| A | |
| |
| PROCEED TO NEXT CIRCUIT INSPECTION SHOWN IN PROBLEM SYMPTOMS TABLE |
|
| 3.CHECK HARNESS AND CONNECTOR (STEERING ANGLE SENSOR - AFS ECU) |
Disconnect the J23 steering angle sensor connector.
Disconnect the A27 AFS ECU connector.
Measure the resistance according to the value(s) in the table below.
- Standard resistance:
| Tester Connection | Condition | Specified Condition |
| J23-7 (SS1-) - A27-8 (SS-) | Always | Below 1 Ω |
| J23-8 (SS1+) - A27-7 (SS+) | Always | Below 1 Ω |
| A27-8 (SS1-) - Body ground | Always | 10 kΩ or higher |
| A27-7 (SS1+) - Body ground | Always | 10 kΩ or higher |
| | REPAIR OR REPLACE HARNESS OR CONNECTOR |
|
|
Reconnect the A27 AFS ECU connector.
Measure the voltage according to the value(s) in the table below.
- Standard voltage:
| Tester Connection | Condition | Specified Condition |
| A27-7 (SS+) - A27-8 (SS-) | Engine switch on (IG) | Approx. 5 V |
| | REPLACE STEERING ANGLE SENSOR |
