Retrieving Codes
Turn ignition off. Insert jumper wire in service check connector terminals, located behind right side of dash. See Fig 1 .
Turn ignition on. Diagnostic Trouble Codes (DTCs) will be indicated by a series of long and short flashes on MIL. The number of long flashes indicates the number in the 10s column. The number of short flashes indicates the number in the 1s column. For example, 4 long flashes followed by 3 short flashes would indicate DTC 43.
See DIAGNOSTIC TROUBLE CODE IDENTIFICATION TABLE table and proceed to appropriate DIAGNOSTIC TROUBLE CODE CHARTS for testing. All voltage tests should be performed with a Digital Volt-Ohmmeter (DVOM) with a minimum 10-megohm input impedance, unless specifically stated differently in testing procedure.
