Diagnostic Trouble Code (DTC) ChartsSpecial Tool(s):
Using a scan tool to retrieve diagnostic trouble codes (DTCs), begin with and correct all non-transmission related DTCs. Start with the U-DTC codes (communication link codes) then 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.
^ For gears 1-3, the limp-home default will be 3rd gear.
^ For gears 4-6, the limp-home default will be 5th gear.
The limp-home gear will be held until the vehicle is placed in R, P or the vehicle has been restarted. After these action(s) the vehicle will default to the limp-home mode of 3rd gear.
