Diagnostic Test
WARNING: This page is about a different car, the 2022 Chrysler Voyager and 2022 Chrysler Pacifica. However, it is still accessible from the selected car via links, so may be relevant.
- CHECK FOR AN ACTIVE DTC
- With the scan tool, read Body Control Module (BCM) DTCs and record on the repair order.
- Record the Environmental Data and any DTCs.
- With the scan tool, erase DTCs.
- Using the recorded Environmental Data, along with the When Monitored and Set Conditions above, operate the vehicle in the conditions that set the DTC.
- With the scan tool, read BCM DTCs.
Did the DTC return?
Yes
- Go To 2
No
- Perform the TESTING FOR AN INTERMITTENT CONDITION procedure. Refer to TESTING FOR AN INTERMITTENT CONDITION .
- CHECK THE PDC ASSEMBLY GROUND CIRCUIT FOR AN OPEN
- Turn the ignition off.
- Disconnect the PDC Assembly harness connector containing the circuit being tested.
- Measure the resistance of the PDC Assembly Ground circuit between ground and the PDC Assembly harness connector.
Is the resistance above 3.0 Ohms?
Yes
- Repair the open in the PDC Assembly Ground circuit.
- Perform the BODY VERIFICATION TEST. Refer to BODY VERIFICATION TEST .
No
- Go To 3
- CHECK THE (W12) REAR WIPER RELAY CONTROL CIRCUIT FOR A SHORT TO VOLTAGE NOTE:
Make sure the Rear Wiper Switch is off when performing this step.
- Turn the ignition off.
- Disconnect the Power Distribution Center (PDC) Assembly harness connector containing the circuit being tested.
- Turn the ignition on.
- Measure the voltage on the (W12) Rear Wiper Relay Control circuit at the PDC Assembly harness connector.
Is there any voltage present?
Yes
- Repair the short to voltage in the (W12) Rear Wiper Relay Control circuit.

No
- Go To 4
- CHECK THE BCM REAR WIPER RELAY OUTPUT FOR PROPER OPERATION
- CHECK THE (W12) REAR WIPER RELAY CONTROL CIRCUIT FOR AN OPEN
- Turn the ignition off.
- Disconnect the BCM C5/E harness connector.
- Measure the resistance of the (W12) Rear Wiper Relay Control circuit between the PDC Assembly harness connector and the BCM C5/E harness connector.
Is the resistance above 3.0 Ohms?
Yes
- Repair the open in the (W12) Rear Wiper Relay Control circuit.
- Perform the BODY VERIFICATION TEST. Refer to BODY VERIFICATION TEST .
No
- Go To 7
- CHECK RELATED PDC ASSEMBLY HARNESS CONNECTIONS
- Disconnect all PDC Assembly harness connectors.
- Disconnect all related in-line harness connections (if equipped).
- Disconnect the related component harness connectors.
- Inspect harness connectors, component connectors, and all male and female terminals for the following conditions:
- Proper connector installation.
- Damaged connector locks.
- Corrosion.
- Other signs of water intrusion.
- Weather seal damage (if equipped).
- Bent terminals.
- Overheating due to a poor connection (terminal may be discolored due to excessive current draw).
- Terminals that have been pushed back into the connector cavity.
- Perform a terminal drag test on each connector terminal to verify proper terminal tension.
Repair any conditions that are found.
- Connect all PDC Assembly harness connectors. Be certain that all harness connectors are fully seated and the connector locks are fully engaged.
- Connect all in-line harness connectors (if equipped). Be certain that all connectors are fully seated and the connector locks are fully engaged.
- Connect all related component harness connectors. Be certain that all connectors are fully seated and the connector locks are fully engaged.
- With the scan tool, erase DTCs.
- Using the recorded Environmental Data, along with the When Monitored and Set Conditions above, operate the vehicle in the conditions that set the DTC.
- With the scan tool, read BCM DTCs.
Did the DTC return?
Yes
- Replace the Power Distribution Center (PDC) Assembly in accordance with the Service Information. Refer to CENTER, POWER DISTRIBUTION (PDC), REMOVAL AND INSTALLATION .
- Perform the BODY VERIFICATION TEST. Refer to BODY VERIFICATION TEST .
No
- Perform the BODY VERIFICATION TEST. Refer to BODY VERIFICATION TEST .
- Test complete.
- CHECK RELATED BCM HARNESS CONNECTIONS
- Disconnect all BCM harness connectors.
- Disconnect all related in-line harness connections (if equipped).
- Disconnect the related component harness connectors.
- Inspect harness connectors, component connectors, and all male and female terminals for the following conditions:
- Proper connector installation.
- Damaged connector locks.
