TEST
1
Ignition on, engine not running.
With the DRBIII , read DTCs and record the related Freeze Frame data.
Is the Good Trip Counter displayed and equal to zero?
Yes → Go To 2
→ Refer to the INTERMITTENT CONDITION symptom in the
No
2
Turn the ignition off.
Disconnect the NVLD electrical harness connector.
Measure the resistance of the NVLD Solenoid coil.
Is the resistance between 7.5 to 8.5 ohms?
Yes → Go To 3
→ Replace the NVLD Assembly.
No
3
Turn the ignition off.
Disconnect the NVLD electrical harness connector.
Disconnect the PCM harness connector.
Measure the resistance between ground and the (K106) NVLD Sol Control circuit at
the NVLD electrical harness connector.
Is the resistance below 5.0 ohms?
Yes → Repair the short to ground in the (K106) NVLD Solenoid Control
→ NOTE: Before continuing, check the PCM harness connector
