ACTION

APPLICABILITY

1

Ignition on, engine not running.
With the DRBIII

t, read DTCs and record the related Freeze Frame data.

Is the Good Trip Counter displayed and equal to zero?

All

Yes

→ Go To 2

No

→ Refer to the INTERMITTENT CONDITION symptom in the

Driveability category.
Perform POWERTRAIN VERIFICATION TEST VER - 5 - NGC.

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?

All

Yes

→ Go To 3

No

→ Replace the NVLD Assembly.

Perform POWERTRAIN VERIFICATION TEST VER - 5 - NGC.

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?

All

Yes

→ Repair the short to ground in the (K106) NVLD Solenoid Control

circuit.
Perform POWERTRAIN VERIFICATION TEST VER - 5 - NGC.

No

→ 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.

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 - NGC.

No

→ Go To 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 - NGC.

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 - NGC.

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.
