Chrysler Crossfire. Manual — part 861
9810 HYDRAULIC SOLENOID S1 SUPPLY VOLTAGE CIRCUIT SHORT TO GROUND (CONTINUED)
•
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: The PTCM senses high current flow on the Hydraulic Solenoid S1 Supply Voltage cir-
cuit.

Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding.
Diagnostic Test
1.
Hydraulic Solenoid S1 Circuit For Short To Ground
Turn the ignition off.
Disconnect the Power Top Control Module C2 harness connector.
Disconnect the Hydraulic Solenoid S1 harness connector.
Note: Check connectors — Clean/repair as necessary.
Measure the resistance between ground and the Hydraulic Solenoid
S1 Supply Voltage circuit.
Is the resistance above 100 kohms?
Yes
>> Go To 2
No
>> Repair the Hydraulic Solenoid S1 Supply Voltage circuit for
a short to ground.
Perform POWER TOP CONTROL MODULE VERIFICA-
TION TEST.
2.
Hydraulic Solenoid S1
With the ignition off.
Reconnect the Hydraulic Solenoid S1 harness connector.
Measure the resistance between the Hydraulic Solenoid S1 Supply
Voltage circuit and the Hydraulic Solenoid S1 Ground circuit.
Is the resistance above 3.0 ohms?
Yes
>> Replace the Power Top Control Module.(Refer to 8 -
ELECTRICAL/ELECTRONIC
CONTROL
MODULES/
POWER TOP CONTROL MODULE - REMOVAL).
Perform POWER TOP CONTROL MODULE VERIFICA-
TION TEST.
No
>> Replace the Power Top Hydraulic Assembly.(Refer to 23 -
BODY/CONVERTIBLE TOP/HYDRAULIC PUMP MOTOR
- REMOVAL).
Perform POWER TOP CONTROL MODULE VERIFICA-
TION TEST.

Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding.
Diagnostic Test
1.
Read DTCs
Turn the ignition on.
With the DRBIII
T
, 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 cir-
cuit 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 CONTROL MODULE VERIFICA-
TION TEST.

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.(Refer to 8 -
ELECTRICAL/ELECTRONIC
CONTROL
MODULES/
POWER TOP CONTROL MODULE - REMOVAL).
Perform POWER TOP CONTROL MODULE VERIFICA-
TION 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 CONTROL MODULE VERIFICA-
TION TEST.
