|
NOTE:
Refer to the Open/Shorted Wire Inspection Description
for the method to inspect the shorted circuit below, then start to inspect according to circumstances.
|
|||||
| AFHT_N shorted to ground inspection | OFF | Not shorted | |||
Results
- If abnormal, there is a problem in the circuit.
PCM Inspection
Test Procedure
- If the other inspection item(s) indicated a normal condition, then it is determined that the PCM is the cause.
Results
- There is a problem with the PCM.
