IG Mode
Normal Conditions
AFHT_N open wire inspection
OFF
There is less than 1 Ohm
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
There is more than 1 MOhm
Results
- If abnormal, there is a problem in the circuit.
If the power supply inspection of the above table showed abnormally, do the additional Power Supply Inspection , to locate the failure.
