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

1.

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.

No

>> Go To 2

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
and Starting.

No

>> Go To 3

3.

VEHICLE HISTORY AND TSB(s)

Continue by reading PCM DTC(s) and record the related Freeze Frame data if any DTC(s) are present.

Whether or not any DTC(s) are present you will want to check the following items which may assist in repairing the
customers complaint successfully.

Check the vehicles repair history.

If the vehicle has a repair history that pertains to the customer’s current complaint, review the repair.

Inpect the vehicle for any aftermarket accessories that may have been installed incorrectly.

Check for any TSB(s) related to the customer’s complaint or DTC(s).

If a TSB applies, follow the instructions per the TSB.

Choose the following scenario that best applies.

The TSB repaired the customers complaint.

Testing complete.

A DTC is present, no TSB applies, or the TSB didn’t repair the customers complaint.

Go To 4

No DTC(s) are present.

Refer to the INTERMITTENT CONDITION Diagnostic Procedure.
