Diagnostic Test

WARNING: This page is about a different car, the 2013 Dodge Avenger and 2013 Chrysler 200. However, it is still accessible from the selected car via links, so may be relevant.

TEST FOR INTERMITTENT CONDITION
NOTE:
The PTCM will only set this fault code when the top operation times out. Maximum timeout is 30 seconds.

NOTE:
If this DTC is active, and the Motor/Pump is operating with limited or no Power Top movement, the most likely cause is a malfunctioning Motor/Pump or Power Top cables.
1. Turn the ignition on.
2. With the scan tool, record and erase all PTCM DTCs.
3. Try to operate the Power Top Switch in the open direction for a minimum of 30 seconds.
4. Try to operate the Power Top Switch in the closed direction for a minimum of 30 seconds.
5. With the scan tool, read all PTCM DTCs.
  Does the scan tool display this DTC as active?
  
  Yes
  - Go To 2
  No
  - The condition that caused this symptom is currently not present. With the scan tool, check the Environmental Data to help identify the conditions in which the DTC was set. Check for an intermittent condition by inspecting the related wiring harness for chafed, pierced, pinched, and partially broken wires. Also, inspect the related connectors for broken, bent, pushed out, spread, corroded, or contaminated terminals. Repair as necessary.
  - Perform the BODY VERIFICATION TEST. Refer to STANDARD PROCEDURE .
DECKLID LATCHED LIMIT SWITCH
1. Turn the ignition off.
2. Disconnect the Decklid Latched Limit Switch harness connector.
3. Connect the leads of an ohmmeter to the two Decklid Latched Limit Switch wires on the switch.
4. Manually toggle the switch while observing the ohmmeter.
  Does the resistance toggle between less than 20.0 Ohms to greater than 10K Ohms?
  
  Yes
  - Go To 3.
  No
  - Replace the Decklid Latched Limit Switch in accordance with the service information.
  - Perform the BODY VERIFICATION TEST. Refer to STANDARD PROCEDURE .

1. Turn the ignition off.
2. Measure the resistance of the (Q974) Decklid Latched Limit Switch Signal circuit between the PTCM C1 harness connector and the Decklid Latched Limit Switch harness connector.
  Is the resistance below 5.0 Ohms?
  
  Yes
  - Go To 5
  No
  - Repair the (Q974) Decklid Latched Limit Switch Signal circuit for an open.
  - Perform the BODY VERIFICATION TEST. Refer to STANDARD PROCEDURE .

1. Measure the resistance between ground and the (Z916) Ground circuit at the Decklid Latched Limit Switch harness connector.
  Is the resistance below 5.0 Ohms?
  
  Yes
  - Replace the Power Top Control Module (PTCM) in accordance with the service information.
  - Perform the BODY VERIFICATION TEST. Refer to STANDARD PROCEDURE .
  No
  - Repair the (Z916) Ground circuit for an open.
  - Perform the BODY VERIFICATION TEST. Refer to STANDARD PROCEDURE .
