TEST
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?
Yes → Go To 4
No
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?
Yes → Repair the short to ground in the (V35) Speed Control Vent
No
5 NOTE: Before continuing, check the PCM harness connector terminals for
