Diagnostic Test

WARNING: This page is about a different car, the 2014 Dodge Journey. However, it is still accessible from the selected car via links, so may be relevant.

DTC IS ACTIVE
NOTE:
If there are any ASD/Main Relay or system voltage DTCs present, diagnose those DTCs before proceeding with this test procedure.
1. Ignition on, engine not running.
2. With the scan tool, select View DTCs. Copy DTC and Freeze Frame information and clear DTCs.
  NOTE:
  Active or pending DTCs may not allow A/C clutch actuation, make sure all DTCs are cleared before proceeding with this test procedure.
3. With the scan tool, actuate the A/C Compressor.
4. Monitor the scan tool for at least two minutes.
5. With the scan tool, select View DTCs.
  Is the status Active for this DTC?
  
  Yes
  - Go To 2
  No
  - Perform the INTERMITTENT CONDITION diagnostic procedure. Refer to INTERMITTENT CONDITION .
A/C CLUTCH RELAY
1. Turn the ignition off.
2. Disconnect the PDC C3 harness connector.
3. Install a know good relay in place of the existing A/C Clutch Relay.
4. Using a scan tool, erase the DTC.
5. Start the engine and turn the A/C on.
  Does the DTC return?
  
  Yes
  - Go To 3
  No
  - Replace the A/C Clutch Relay.
  - Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .

1. Turn the ignition off.
2. Disconnect the PDC C3 harness connector.
3. Disconnect the PCM C1 harness connector.
4. Measure the resistance between ground and the (C13) A/C Clutch Relay Control circuit in the PCM C1 harness connector.
  Is the resistance below 100 Ohms?
  
  Yes
  - Repair the short to ground in the (C13) A/C Clutch Relay Control circuit.
  - Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .
  No
  - Go To 5
(C13) A/C CLUTCH CONTROL CIRCUIT OPEN OR HIGH RESISTANCE IN THE PDC
1. Measure the resistance of the (C13) A/C Clutch Control circuit between the Relay terminal and the PDC C3 harness connector.
  Is the resistance below 5.0 Ohms?
  
  Yes
  - Go To 5
  No
  - Replace the PDC for an open in accordance with the service information.
  - Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .
(C13) A/C CLUTCH CONTROL CIRCUIT OPEN OR HIGH RESISTANCE BETWEEN THE PCM AND PDC
1. Measure the resistance of the (C13) A/C Clutch Control circuit between PCM C1 harness connector and the PDC C3 harness connector.
  Is the resistance below 5.0 Ohms?
  
  Yes
  - Go To 6
  No
  - Replace the PDC for an open in accordance with the service information.
  - Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .
(C13) A/C CLUTCH CONTROL CIRCUIT SHORTED TO GROUND IN THE PDC
1. Measure the resistance between ground and the (C13) A/C Clutch Control circuit at the Relay terminal.
  Is the resistance below 100 Ohms?
  
  Yes
  - Replace the PDC for an internal short to ground in accordance with the service information.
  - Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .
  No
  - Go To 7
POWERTRAIN CONTROL MODULE (PCM)
1. Using the wiring diagram/schematic as a guide, inspect the wiring and connectors between the Totally Integrated Power Module (TIPM) and the Powertrain Control Module (PCM).
2. Look for any chafed, pierced, pinched or partially broken wires.
3. Look for broken, bent, pushed out or corroded terminals. Verify that there is good pin to terminal contact in the related connectors.
4. Perform any Technical Service Bulletins that may apply.
  Were any problems found?
  
  Yes
  - Repair as necessary.
  - Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .
  No
  - Replace and program the Powertrain Control Module (PCM) in accordance with the Service Information. Refer to MODULE, POWERTRAIN CONTROL, REMOVAL .
  - Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .
