P1595-SPEED CONTROL SOLENOID CIRCUITS —
TEST
1 Turn the ignition off.
Disconnect the Speed Control Servo harness connector.
Note: Ensure the Brake Pedal is not depressed during the following steps.
Remove the ASD relay and jumper relay socket pins 30 and 87.
Turn the ignition on.
Turn Speed Control Switch on.
With the DRBIII , actuate the Speed Control Vacuum Solenoid.
Using a 12-volt Test Light connected to ground, check the Brake Lamp Switch
Output circuit at the Speed Control Servo connector.
Is the light illuminated and bright?
Yes → Go To 2
→ Go To 8
No
2 Turn the ignition off.
Disconnect the Speed Control Servo harness connector.
Measure the resistance between ground and the Speed Control Servo ground circuit
at the Speed Control Servo connector.
Is the resistance below 5.0 ohms?
Yes → Go To 3
→ Repair open Ground Circuit at S/C Servo Connector.
No
3 Turn the ignition off.
Disconnect the Speed Control Servo harness connector.
Disconnect PCM harness connectors.
Measure the resistance of the Speed Control Vacuum Solenoid Control circuit
between the PCM connector and the Speed Control Servo connector.
Is the resistance below 5.0 ohms?
Yes → Go To 4
→ Repair the open S/C Vacuum Solenoid Control Circuit.
No
4 Turn the ignition off.
Disconnect the Speed Control Servo harness connector.
Disconnect PCM harness connectors.
Using a 12-volt Test Light connected to 12-volts, check the Speed Control Vacuum
Solenoid Control circuit at the Speed Control Servo connector.
Is the light illuminated and bright?
Yes → Repair the short to ground in the S/C Vacuum Solenoid Control
→ Go To 5
No
5 Turn the ignition off.
Disconnect the Speed Control Servo harness connector.
Disconnect PCM harness connectors.
Measure the resistance of the Speed Control Vent Solenoid Control circuit between
the Speed Control Servo connector and PCM connector.
Is the resistance below 5.0 ohms?
Yes → Go To 6
→ Repair the open Speed Control Vent Solenoid Control Circuit.
No
