Diagnostic Test

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

CHECK FOR AN ACTIVE DTC
1. Turn the ignition on.
2. With the scan tool, record the related Freeze Fame Data and clear the DTCs in the Powertrain Control Module (PCM).
3. Start the engine and allow it to reach normal operating temperature. Hold engine speed greater than 1000 rpm for at least one minute. The DTC will not set unless cam phasing becomes active, which may not occur if speed never leaves idle.
  WARNING:
  When the engine is operating, do not stand in direct line with the fan. Do not put your hands near the pulleys, belts, or fan. Do not wear loose clothing. Failure to follow these instructions can result possible serious or fatal injury.
4. With the scan tool, read DTCs.
  Is the DTC active or pending?
  
  Yes, non VCT vehicles
  - Go To 3
  Yes, vehicles with VCT
  - Go To 2
  No
  - Perform the INTERMITTENT CONDITION diagnostic procedure. Refer to INTERMITTENT CONDITION .
CAMSHAFT POSITION SOLENOID CLEANING
1. With the scan tool perform the Exhaust Phaser 1 Cleaning function.
  Did the DTC reset?
  
  Yes
  - Go To 3
  No
  - Repair complete.
  - Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .
CHECK THE (K442) VCT CONTROL CIRCUIT FOR A SHORT TO VOLTAGE
1. Turn the ignition off.
2. Disconnect the VCT Solenoid harness connector.
3. Disconnect the PCM C2 harness connector.
4. Turn the ignition on.
5. Measure the voltage between ground and the (K442) VCT Control circuit at the VCT Solenoid harness connector.
  Is the voltage greater than 0.1 volt?
  
  Yes
  - Repair the short to voltage in the (K442) VCT Control circuit.
  - Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .
  No
  - Go To 4
CHECK FOR EXCESSIVE RESISTANCE IN THE (K442) VCT CONTROL CIRCUIT
1. Turn the ignition off.
  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.
2. Connect the (special tool #10436, Adapter, GPEC Diagnostic).
3. Measure the resistance of the (K442) VCT Control circuit between the VCT Solenoid harness connector and the GPEC Adaptor.
  Is the resistance below 3.0 Ohms?
  
  Yes
  - Go To 5
  No
  - Repair the high resistance in the (K442) VCT Control circuit.
  - Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .
CHECK THE (K442) VCT CONTROL CIRCUIT FOR A SHORT TO GROUND
1. Check for continuity between ground and the (K442) VCT Control circuit at the VCT Solenoid harness connector.
  Is there continuity between ground and the (K442) VCT Control circuit?
  
  Yes
  - Repair the (K442) VCT Control circuit for a short to ground.
  - Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .
  No
  - Go To 6
VCT SOLENOID
1. Connect the PCM C2 harness connector.
2. Turn the ignition on.
3. Using a 12-volt test light connected to 12 volts probe the (K442) VCT Control circuit in the VCT Solenoid harness connector.
  NOTE:
  The test light should be off unless you have a short to ground, except for a brief period immediately after turning ignition on.
4. With the scan tool, actuate the VCT Solenoid control to the ON (100%) position.
  NOTE:
  The test light should be illuminated and bright. Compare the brightness to that of a direct connection to the battery.
  
  Is the test light illuminated and bright during the actuation and was it off when required?
  
  Yes
  - Verify that there is good pin to terminal contact in the VCT Solenoid and Powertrain Control Module connectors. If OK, replace the VCT Solenoid in accordance with the Service Information.
  - Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .
  No
  - Go To 7
CHECK FOR EXCESSIVE RESISTANCE IN THE GROUND CIRCUIT
1. Turn the ignition off.
2. Measure the resistance between ground and the Ground circuit at the VCT Solenoid harness connector.
  Is the resistance below 3.0 Ohms?
  
  Yes
  - Go To 8
  No
  - Repair the excessive resistance in the VCT Solenoid ground control circuit.
  - Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .
CHECK RELATED PCM AND COMPONENT CONNECTIONS
1. Perform any Service Bulletins that apply.
2. Disconnect all PCM harness connectors.
3. Disconnect all related in-line harness connections (if equipped).
4. Disconnect the related component harness connectors.
5. 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.
  - Check for spread terminals and verify proper terminal tension.
  Repair any conditions that are found.
6. Reconnect all PCM harness connectors. Be certain that all harness connectors are fully seated and the connector locks are fully engaged.
7. Reconnect all in-line harness connectors (if equipped). Be certain that all connectors are fully seated and the connector locks are fully engaged.
8. Reconnect all related component harness connectors. Be certain that all connectors are fully seated and the connector locks are fully engaged.
9. With the scan tool, erase DTCs.
10. Test drive or operate the vehicle in accordance with the when monitored and set conditions.
11. With the scan tool, read DTCs.
  Did the DTC return?
  
  Yes
  - Replace the Powertrain Control Module in accordance with the Service information. Refer to MODULE, POWERTRAIN CONTROL, REMOVAL .
  - Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .
  No
  - Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .
  - Test complete.
