TEST ACTION APPLICABILITY
9 Turn the ignition off.
Disconnect the NVLD electrical harness connector.
Measure the resistance between the (Z1) Ground circuit and ground.
Is the resistance below 5.0 ohms?
All
Yes → Go To 10
No → Repair the open in the (Z1) Ground circuit.
Perform POWERTRAIN VERIFICATION TEST VER-5-NGC.
10 Turn the ignition off.
Disconnect the NVLD electrical harness connector.
Disconnect the PCM harness connector.
CAUTION: DO NOT PROBE THE PCM HARNESS CONNECTORS. PROBING
THE PCM HARNESS CONNECTORS WILL DAMAGE THE PCM TERMI-
NALS RESULTING IN POOR TERMINAL TO PIN CONNECTION. INSTALL
MILLER SPECIAL TOOL #8815 TO PERFORM DIAGNOSIS.
Measure the resistance of the (K107) NVLD Switch Signal circuit from the NVLD
electrical harness connector to the appropriate terminal of the special tool #8815.
Is the resistance below 5.0 ohms?
All
Yes → NOTE: Before continuing, check the PCM harness connector
terminals for corrosion, damage or terminal push out. Repair as
necessary. Replace and program the Powertrain Control Module
in accordance with the Service Information.
Perform POWERTRAIN VERIFICATION TEST VER-5-NGC.
No → Repair the open in the (K107) NVLD Switch Signal Circuit.
Perform POWERTRAIN VERIFICATION TEST VER-5-NGC.
