Diagnostic Test

WARNING: This page is about a different car, the 2016 Dodge Journey and 2015 Dodge Journey. However, it is still accessible from the selected car via links, so may be relevant.

ACTIVE DTC
NOTE:
If the P0685 and P0688 DTCs are both present, diagnose and repair the P0685 DTC before the P0688.
1. Ignition on, engine not running.
2. With the scan tool, select View DTCs.
  Is the DTC Active at this time?
  
  Yes
  - Go To 2
  No
  - Perform the INTERMITTENT CONDITION diagnostic procedure. Refer to INTERMITTENT CONDITION . .
ASD CONTROL OPERATION FROM THE PCM
1. Turn the ignition off.
2. Disconnect the C3 PDC harness connector.
3. With a 12-volt test light connected to battery voltage, probe the (K51) ASD Control circuit in the PDC C3 harness connector.
4. Ignition on, engine not running.
5. Using the scan tool in the PCM, actuate the ASD Relay.
  Does the test light illuminate brightly and flash on an off?
  
  Yes
  - Before continuing, check the PDC harness connector terminals for corrosion, damage or terminal push out. Repair as necessary. If OK, replace the PDC in accordance with the Service Information.
  - Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST . .
  No
  - Go To 3
(K51) ASD CONTROL CIRCUIT SHORTED TO VOLTAGE
1. Stop the ASD actuation.
2. Turn the ignition off.
3. Ignition on, engine not running.
4. Measure the voltage on the (K51) ASD Control circuit at the C3 PDC harness connector.
  Is there any voltage present?
  
  Yes
  - Repair the short to voltage in the (K51) ASD Control circuit.
  - Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST . .
  No
  - Go To 4
(K51) ASD CONTROL CIRCUIT OPEN
1. Turn the ignition off.
2. Measure the resistance of the (K51) ASD Control circuit from the C3 PDC harness connector to the appropriate terminal of PCM harness connector.
  Is the resistance below 5.0 Ohms?
  
  Yes
  - Go To 5
  No
  - Repair the open in the (K51) ASD Control circuit.
  - Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST . .
(K51) ASD CONTROL CIRCUIT SHORTED TO GROUND
1. Measure the resistance between ground and the (K51) ASD Control circuit in the PDC C3 harness connector.
  Is the resistance below 10k Ohms?
  
  Yes
  - Repair the short to ground in the (K51) ASD Control circuit.
  - Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST . .
  No
  - Go To 6
POWERTRAIN CONTROL MODULE (PCM)
1. Using the wiring diagram/schematic as a guide, inspect the wiring and connectors between the related PDC 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 PDC and Powertrain Control Module connectors.
4. Perform any Technical Service Bulletins that may apply.
  Were there 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 . .
