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