4.
(Z155) S/C GROUND CIRCUIT OPEN
Turn the ignition off.
Disconnect the S/C Servo harness connector.
Measure the resistance between ground and the (Z155) S/C Ground
circuit at the S/C Servo harness connector.
Is the resistance below 5.0 ohms?
Yes
>> Go To 5
No
>> Repair the open in the (Z155) S/C Ground circuit.
Perform POWERTRAIN VERIFICATION TEST. (Refer to 9
- ENGINE - STANDARD PROCEDURE)
5.
SPEED CONTROL VACUUM SOLENOID
Ignition on, engine not running.
With the scan tool, actuate the Speed Control Vacuum Solenoid.
Using a 12-volt test light connected to battery voltage, probe the (V36)
S/C Vacuum Control circuit.
Does the test light illuminate brightly and flash on and off?
Yes
>> Replace the Speed Control Servo.
Perform POWERTRAIN VERIFICATION TEST. (Refer to 9

6.
(V36) S/C VACUUM SOL CONTROL CIRCUIT OPEN
Turn the ignition off.
Disconnect the C3 PCM harness connector.
CAUTION: Do not probe the PCM harness connectors. Probing
the PCM harness connectors will damage the PCM terminals
resulting in poor terminal to pin connection. Install Miller Special
Tool #8815 to perform diagnosis.
Measure the resistance of the (V36) S/C Vacuum 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 7
No
>> Repair the open/high resistance in the (V36) S/C Vacuum
Sol Control circuit.
Perform POWERTRAIN VERIFICATION TEST. (Refer to 9
- ENGINE - STANDARD PROCEDURE)
7.
(V36) SPEED CONTROL VACUUM SOLENOID CONTROL CIRCUIT SHORTED TO GROUND
Measure the resistance between ground and the (V36) S/C Vacuum
Solenoid Control circuit at the Speed Control Servo harness connector.
Is the resistance below 100 ohms?
Yes
>> Repair the short to ground in the (V36) S/C Vacuum Sol
Control circuit.
Perform POWERTRAIN VERIFICATION TEST. (Refer to 9
- ENGINE - STANDARD PROCEDURE)
No
>> Go To 10
