3
Turn the ignition off.
Disconnect the NVLD Assembly harness connector.
Disconnect the PCM harness connector.
Turn the ignition on.
Measure the voltage on the (K106) NVLD Sol Control circuit in the NVLD Assembly
harness connector.
Is the voltage above 1.0 volt?
All
Yes
→ Repair the short to battery voltage in the (K106) NVLD Sol
Control circuit.
Perform POWERTRAIN VERIFICATION TEST VER - 5.
No
→ Go To 4
4
Turn the ignition off.
Disconnect the NVLD Assembly 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 (K106) NVLD Sol Control circuit from the NVLD
Assembly harness connector to the appropriate terminal of special tool #8815.
Is the resistance below 5.0 ohms?
All
Yes
→ Go To 5
No
→ Repair the open in the (K106) NVLD Sol Control circuit.
Perform POWERTRAIN VERIFICATION TEST VER - 5.
5
Turn the ignition off.
Disconnect the NVLD Assembly harness connector.
Measure the resistance between the (Z1) Ground circuit and ground.
Is the resistance below 5.0 ohms?
All
Yes
→ Go To 6
No
→ Repair the open in the (Z1) Ground circuit.
Perform POWERTRAIN VERIFICATION TEST VER - 5.

NOTE: Before continuing, check the PCM harness connector terminals for
corrosion, damage, or terminal push out. Repair as necessary.
If there are no possible causes remaining, view repair.
