9811 - HYDRAULIC SOLENOID S1 SUPPLY VOLTAGE CIRCUIT OPEN/SHORT TO B(+)





- When Monitored: With the ignition on, the Power Top Control Module (PTCM) continuously senses the voltage on the Hydraulic Solenoid S1 Supply Voltage circuit.
- Set Condition: When the PTCM senses B(+) on the Hydraulic Solenoid S1 Supply Voltage circuit.





Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding.

Diagnostic Test

1. Read DTCs





Turn the ignition on.

With the DRBIII(R), read Current DTCs.

Are both Hydraulic Solenoid S1/S2 Supply Circuit Open/Short to B(+) DTCs set?

Yes

- Go To 6

No

- Go To 2

2. Hydraulic Solenoid S1 Supply Voltage circuit For Short To B(+)





Turn the ignition off.

Disconnect the Power Top Control Module C2 harness connector.

NOTE: Check connectors - Clean/repair as necessary.


Turn the ignition on.

Measure the voltage of the Hydraulic Solenoid S1 Supply Voltage circuit at the Power Top Control Module C2 harness connector.

Is the voltage below 1.0 volts?

Yes

- Go To 3

No

- Repair the Hydraulic Solenoid S1 Supply Voltage circuit for a short to B(+).
- Perform POWER TOP VERIFICATION TEST Power Top Verification Test.

3. Hydraulic Solenoid S1





With the ignition off.

Measure the resistance between the Hydraulic Solenoid S1 Supply Voltage circuit and the Hydraulic Solenoid S1/S2 Ground circuit from the Power Top Control Module C2 harness connector.

Is the resistance between 6.0 - 15.0 ohms?

Yes

- Replace the Power Top Control Module.
- Perform POWER TOP VERIFICATION TEST Power Top Verification Test.

No

- Go To 4

4. Open Hydraulic Solenoid S1 Supply Voltage circuit





With the ignition off.

Disconnect the Hydraulic Solenoid S1 harness connector.

Measure the resistance of the Hydraulic Solenoid S1 Supply Voltage circuit from the Power Top Control Module C2 harness connector to the Hydraulic Solenoid S1 harness connector.

Is the resistance below 5.0 ohms?

Yes

- Go To 5

No

- Repair the Hydraulic Solenoid S1 Supply Voltage circuit for an open.
- Perform POWER TOP VERIFICATION TEST Power Top Verification Test.

5. Open Hydraulic Solenoid S1/S2 Ground circuit





With the ignition off.

Measure the resistance of the Hydraulic Solenoid S1/S2 Ground circuit from the Power Top Control Module C2 harness connector to the Hydraulic Solenoid S1 harness connector.

Is the resistance below 5.0 ohms?

Yes

- Replace the Power Top Hydraulic Assembly.
- Perform POWER TOP VERIFICATION TEST Power Top Verification Test.

No

- Repair the Hydraulic Solenoid S1/S2 Ground circuit for an open.
- Perform POWER TOP VERIFICATION TEST Power Top Verification Test.

6. PTCM





Turn the ignition off.

Measure the resistance between ground and the Hydraulic Solenoid S1/S2 Ground circuit by backprobing from the Power Top Control Module C2 harness connector.

Is the resistance below 5.0 ohms?

Yes

- Repair the Hydraulic Solenoid S1/S2 Ground circuit for an open.
- Perform POWER TOP VERIFICATION TEST Power Top Verification Test.

No

- Replace the Power Top Control Module.
- Perform POWER TOP VERIFICATION TEST Power Top Verification Test.
