DIAGNOSIS AND TESTING
| Procedure revision date: 01/07/2013
|
Vehicle Communication Module (VCM) and Integrated Diagnostic System (IDS) software with appropriate hardware, or equivalent scan tool
|
Using a scan tool to retrieve DTCs, begin with and repair all non-transmission related DTCs. Start with the U-DTCs (communication link codes) and repair any transmission related DTCs.
Limp-home mode is a default condition to protect the engine and transmission when a fault occurs. Limp-home mode depends on the actual gear the vehicle was in when the fault has occurred.
The limp-home gear is held until the vehicle is placed in REVERSE, PARK or the vehicle is restarted. After these action(s) the vehicle defaults to the limp-home mode of 3rd gear.
