PRE-DIAGNOSTIC TROUBLESHOOTING PROCEDURE

For the Engine circuit diagram (Refer to 9 - ENGINE - SCHEMATICS AND DIAGRAMS).

For a complete wiring diagram Refer to Section 8W.

Diagnostic Test

NO RESPONSE

Make sure the scan tool will communicate with the appropriate modules.

Are you currently experiencing a NO RESPONSE condition?

Yes

>> The NO RESPONSE condition must be properly diagnosed before continuing.

Refer to the appropriate BUS Communication test in Section 8 ELECTRONIC CONTROL MODULES -
ELECTRICAL DIAGNOSTICS.

>> Go To 2

NO START

Is the customer complaint a NO START condition?

Yes

>> Check the vehicle for any NO START related PCM DTC(s) or Vehicle Theft Security related DTC(s).

If no Theft related DTC(s) are present, refer to the Non DTC Diagnostic Procedures that relate to Fuel
