INSPECTION PROCEDURE
- NOTICE:
- If the power steering ECU assembly or steering column assembly has been replaced, perform the torque sensor zero point calibration (Click here).
1.CHECK CAN COMMUNICATION SYSTEM |
Check if CAN communication system DTCs are output (Click here).

3.CHECK HARNESS AND CONNECTOR (TS of DLC3 - POWER STEERING ECU ASSEMBLY) |
Turn the ignition switch off.
Disconnect the power steering ECU connector.
Measure the resistance according to the value(s) in the table below.
- Standard Resistance:
Tester Connection Condition Specified Condition D102-12 (TS) - D104-6 (TS) Always Below 1 Ω D102-12 (TS) - Body ground Always 10 kΩ or higher
Reconnect the power steering ECU connector.

OK | |
4.CHECK HARNESS AND CONNECTOR (CG of DLC3 - BODY GROUND) |
Measure the resistance according to the value(s) in the table below.
- Standard Resistance:
Tester Connection Condition Specified Condition D102-4 (CG) - Body ground Always Below 1 Ω
|
| ||||
OK | |
5.INSPECT POWER STEERING ECU ASSEMBLY |
Turn the ignition switch off.
Using SST, connect terminals TS and CG of the DLC3.
Turn the ignition switch to ON.
Check that the PS warning light is blinking.
