Diagnostic Test

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.
  - Refer to STANDARD PROCEDURE and perform the BODY VERIFICATION TEST.
