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 DTC is obtained, refer to appropriate DTC test procedure under DIAGNOSTIC TESTS .

⁽³⁾

⁽¹⁾	Most DTCs use 2 trip malfunction detection logic that requires 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 sets on the first detection of the malfunction.

⁽³⁾	All DTCs P07XX and P1751 are automatic transmission-related. See appropriate DIAGNOSIS article in AUTOMATIC TRANSMISSIONS.
