Diagnostic Trouble Code Definitions

NOTE: DTCs can only be retrieved by using a scan tool. See ENTERING ON-BOARD DIAGNOSTICS  under SELF-DIAGNOSTIC SYSTEM.

When Diagnostic Trouble Code (DTC) is obtained, refer to appropriate DTC test procedure under DIAGNOSTIC TESTS  .

(1) Some DTCs use 2 trip malfunction detection logic that required DTC to set 2 times during 2 separate drive cycles for MIL to illuminate. If DTC is for a fault that may affect emissions, MIL will also illuminate.

(2) This DTC will set when first trip fault is detected.

(3) For diagnostic procedures, see appropriate DIAGNOSIS article in AUTOMATIC TRANSMISSION.
