Test Step 1 - Record and Erase All Theft and Security System DTCs

With the scan tool, record and erase all DTCs from all theft/security system modules. Monitor for any active codes as you work through the following steps.

Review the code monitor and set conditions for any DTCs that are stored and attempt to reproduce the conditions listed.

Wiggle the wiring harness and connectors of the related circuit, sensor or component

Turn the ignition OFF. Refer to any TSBs that may apply

Was the source of the customer complaint found or did any DTCs appear and stay active?

Yes

Perform the appropriate diagnostic procedure.

No

Go to Test Step 2

Test Step 2 - Attempt to Reproduce the Condition

In the event the customer complaint cannot be duplicated due to an intermittent condition, the following may aid in attempting to reproduce the condition.

Using the wiring diagram/schematic as a guide, inspect the wiring and connectors related to the stored code or component in question.

Look for chafed, pierced, pinched, or partially broken wires and broken, bent, pushed out, spread, corroded, or contaminated terminals.

If the customer concern was related to a specific fob-in-key, ensure the FOBIK in question is used while attempting reproduce the condition.

Reconnect any disconnected components and harness connectors and ensure they are properly seated.

If numerous trouble codes were set, use a schematic and inspect any common ground or supply circuits

Was the source of the intermittent condition located?

Yes

Make the appropriate repairs.

No

The problem cannot be found at this time. If repeated intermittent failures are encountered that cannot be reproduced and the condition has prompted multiple customer visits to the dealership, document any findings on the repair order.
