Turn ignition switch off. Connect Honda PGM tester or OBD-II scan tool to 16-pin Data Link Connector (DLC) located under drivers side of instrument panel near center console. See Figure . Turn ignition on. 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. See DIAGNOSTIC TROUBLE CODE DEFINITIONS and proceed to appropriate DTC testing.
