Diagnostic Trouble Code (DTC) Information







Diagnostic trouble code (DTC) information ECM-P053400

Condition

- Engine running.
- Air conditioning (A/C) control, active.

Note! The control module can only detect the fault once the test has been started and the diagnostic trouble code (DTC) is stored when the conditions are met.
