TEST ACTION APPLICABILITY
3 Turn the ignition off.
Disconnect the S/C Servo 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 (V35) S/C Vent Sol Control circuit from the Speed
Control Servo harness connector to the appropriate terminal of special tool #8815.
Is the resistance below 5.0 ohms?
All
Yes → Go To 4
No → Repair the open/high resistance in the (V35) S/C Vent Sol Control
circuit.
Perform POWERTRAIN VERIFICATION TEST VER-4-NGC.
4 Turn the ignition off.
Disconnect the S/C Servo harness connector.
Disconnect the PCM harness connector.
Measure the resistance between ground and the (V35) S/C Vent Sol Control circuit at
the Speed Control Servo harness connector.
Is the resistance below 100 ohms?
All
Yes → Repair the short to ground in the (V35) Speed Control Vent
Solenoid Control circuit.
Perform POWERTRAIN VERIFICATION TEST VER-4-NGC.
No → Go To 5
5 NOTE: Before continuing, check the PCM harness connector terminals for
corrosion, damage, or terminal push out. Repair as necessary.
If the there are no possible causes remaining, view repair.
All
Repair
Replace and program the Powertrain Control Module in accor-
dance with the Service Information.
Perform POWERTRAIN VERIFICATION TEST VER-4-NGC.
