Monitor strategy
Typical enabling conditions
Typical malfunction thresholds
Component operating range
Inspection procedure
Read current dtc
If any dtcs other than p0630 are output, troubleshoot those dtcs first.
Notice:
If p0630 is set, the vin must be input to the ecm using the intelligent tester. However, all dtcs are cleared automatically by the tester when the vin is input. If dtcs other than p0630 are set, check them first.
Power supply relay failure
Description
If the power steering ecu detects these dtcs, it shuts off the motor relay
circuit (built into the power
steering ecu) and stops power assist.
Inspection procedure
