2 Turn the ignition off.
Disconnect the PCM harness connector.
Disconnect the Brake Lamp Switch 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 Power Supply circuit from the Brake Lamp
Switch harness connector to the appropriate terminal of special tool #8815.
Is the resistance below 5.0 ohms?
Yes → Go To 3
→ Repair the open/high resistance in the (V32) S/C Power Supply
No
3 Turn the ignition off.
Disconnect the PCM harness connector.
Disconnect the Brake Switch harness connector.
Measure the resistance between ground and the (V32) S/C Power Supply circuit in
the Brake Switch harness connector.
Is the resistance below 100 ohms?
Yes → Go To 4
→ Repair the short to ground in the (V32) S/C Power Supply circuit.
No
4 Turn the ignition off.
Disconnect the S/C Servo harness connector.
Disconnect the Brake Switch harness connector.
Measure the resistance of the (V40) S/C Brake Switch Output circuit from the Brake
Switch harness connector to the S/C Servo harness connector.
Is the resistance below 5.0 ohms?
Yes → Go To 5
→ Repair the open/high resistance in the (V40) S/C Brake Switch
No
5 Turn the ignition off.
Disconnect the Speed Control Servo harness connector.
Disconnect the Brake Switch harness connector.
Measure the resistance between ground and the (V40) S/C Brake Switch Output
circuit at the Speed Control Servo harness connector.
Is the resistance below 100 ohms?
Yes → Repair the short to ground in the (V40) S/C Brake Switch Output
→ Go To 6
No
