7
Turn the ignition off.
Disconnect the S/C Servo harness connector.
Disconnect the C3 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.
No
→ Go To 10
8
Turn the ignition off.
Disconnect the Brake Lamp Switch harness connector.
Disconnect the C3 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 (V32) S/C Supply circuit from the Brake Lamp Switch
harness connector to the appropriate terminal of special tool # 8815.
Is the resistance below 5.0 ohms?
All
Yes
→ Go To 9
No
→ Repair the open/high resistance in the (V32) S/C Supply circuit.
Perform POWERTRAIN VERIFICATION TEST VER - 4.

Turn the ignition off.
Disconnect the Brake Switch harness connector.
Disconnect the C3 PCM harness connector.
Measure the resistance between ground and the (V32) S/C Supply circuit at the
Speed Control Servo harness connector.
Is the resistance below 100 ohms?
All
Yes
→ Repair the short to ground in the (V32) S/C Supply circuit.
Perform POWERTRAIN VERIFICATION TEST VER - 4.
No
→ Go To 10

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.
