Diagnostic Tests: Notes

CAUTION: Perform all resistance and voltage tests with a Digital Volt-Ohmmeter (DVOM) with minimum 10-megohm impedance, unless stated otherwise in test procedures. If the inspection for a particular failure code requires the test harness, remove the seat back panels. Unbolt the ECM bracket to backprobe ECM connectors. Check the system according to the procedure described for the appropriate code. For backprobe procedure, see Figure .

NOTE: Malfunction Indicator Light (MIL) may also be referred to as Check Engine Light.

NOTE: For identification of circuits, terminals and wire colors referenced in the following testing, see appropriate WIRING DIAGRAMS article. For connector identification and locations, see Figure -Figure .
