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.

PENDING TEMPERATURE SENSOR DTCS
1. Turn the ignition on.
2. Start the engine and allow it to reach operating temperature.
3. With the scan tool, select View DTCs.
  Are there any pending Engine Coolant Temperature sensor, Ambient Air Temperature sensor, or general temperature DTCs?
  
  Yes
  - Diagnose and repair any temperature sensor DTCs and retest.
  - Perform the POWERTRAIN VERIFICATION TEST. Refer to PCM VERIFICATION TEST .
  No
  - Go To 2
ACTIVE DTC
1. Turn the ignition on.
2. With the scan tool, select View DTCs and review the DTC environmental information for this DTC.
  Is the good trip counter greater than 0?
  
  Yes
  - The DTC is not active at this time. Perform the INTERMITTENT CONDITION diagnostic procedure. Refer to INTERMITTENT CONDITION .
  No
  - Go To 3
STUCK ENGINE OFF TIMER
1. Using the scan tool under the PCM Data menu, read and record the IGNITION OFF TIME.
2. Start and allow the engine to idle.
3. Turn key off and remove from ignition switch for exactly three minutes and 15 seconds.
4. Turn key on but leave engine off.
5. Using the scan tool read the IGNITION OFF TIME.
  Does the most recent IGNITION OFF TIME equal three minutes?
  
  Yes
  - Go To 5
  No
  - Go To 4
IGNITION OFF TIME
1. Compare the IGNITION OFF TIME written down with the IGNITION OFF TIME after the 3 minute 15 second shutdown.
  Did it change?
  
  Yes
  - Go To 5
  No
  - Go To 7
LOW BATTERY VOLTAGE AT PCM
NOTE:
A loss of battery voltage to the module while the module is powered down is the most likely cause of this DTC.
1. Inspect all PCM power and ground circuits.
2. Inspect and test the battery in accordance with the service information.
3. Inspect the generator drive belt for proper alignment and adjustment.
4. Inspect the vehicle for aftermarket accessories that may exceed the generator system output.
5. Inspect the fuses in the IPM. If an open fuse is found, use the wire diagram/schematics as a guide and inspect the wiring and connectors for a damaged or shorted circuit.
  Were any problems found?
  
  Yes
  - Repair as necessary.
  - Perform the POWERTRAIN VERIFICATION TEST. Refer to PCM VERIFICATION TEST .
  No
  - Go To 6
CHECK THE FUSED B+ CIRCUIT FOR AN OPEN/HIGH RESISTANCE
CAUTION:
Do not probe the PCM harness connectors. Probing the PCM harness connectors will damage the PCM terminals resulting in poor terminal to pin connection. Install the GPEC Diagnostic Adaptor to perform the diagnosis.
1. Connect the (special tool #10436, Adapter, GPEC Diagnostic).
2. With a 12-volt test light connected to ground, check the Fused B+ circuit at the GPEC Adaptor.
3. Check the circuit with the ignition switch in the OFF, ON, and START positions.
  NOTE:
  The test light should be illuminated and bright regardless of the position of the ignition switch. Compare the brightness to that of a direct connection to the battery.
4. Wiggle test the circuits while checking with the test light to check the circuit for an intermittent problem.
  Is the test light illuminated and bright in each of the ignition switch positions?
  
  Yes
  - Go To 8
  No
  - Repair the Fused B+ circuit as necessary.
  - Perform the POWERTRAIN VERIFICATION TEST. Refer to PCM VERIFICATION TEST .
RESET STUCK TIMER
1. Turn the ignition off.
2. Disconnect the PCM harness connectors for five minutes.
3. Reconnect the PCM harness connectors.
4. Start and allow the vehicle to Idle for 30 seconds.
5. Turn key off and remove from ignition switch for exactly two minutes and 15 seconds.
6. Ignition on, engine not running.
7. Using the scan tool go into PCM DATA menu, read the IGNITION OFF TIME.
  Did the timer equal two minutes?
  
  Yes
  - Test Complete.
  - Perform the POWERTRAIN VERIFICATION TEST. Refer to PCM VERIFICATION TEST .
  No
  - Go To 8
POWERTRAIN CONTROL MODULE (PCM)
1. Using the wiring diagram/schematic as a guide, inspect Powertrain Control Module power and ground circuits.
2. Look for any chafed, pierced, pinched, or partially broken wires.
3. Look for broken, bent, pushed out or corroded terminals.
4. Monitor the scan tool data and wiggle test the wiring and connectors.
5. Look for the any data to change or for the DTC to reset during the wiggle test.
6. Perform any Technical Service Bulletins that may apply.
  Were any problems found?
  
  Yes
  - Repair as necessary.
  - Perform the POWERTRAIN VERIFICATION TEST. Refer to PCM 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 PCM VERIFICATION TEST .
