Check for and note any DTCs. See DIAGNOSTIC TROUBLE CODE DEFINITIONS and proceed to appropriate DTC testing. Also check for and note freeze frame data.

See Fig 1. Turn ignition on. Diagnostic Trouble Codes (DTCs) will be indicated by a series of long and short flashes of MIL. The number of long flashes indicates number in tens column. The number of short flashes indicates number in ones column. For example, 4 long flashes followed by 3 short flashes would indicate DTC 43.
