Customer Preference Items
This method is used to enable or disable module-controlled items or systems to suit the preference of the customer. Not all features controlled by the module are listed in this configuration method. Refer to the MODULE CONFIGURATION INDEX for a list of features for each module.
If a feature is changed using the customer preference items configuration method, the changed information will not be stored in the PCM VID block. The VID block will retain the original settings as they were recorded when the vehicle left the factory.

- Visually inspect for obvious signs of electrical damage. Refer to the following chart
- If the concern remains after inspection, connect the WDS or equivalent Tester to the data link connector (DLC) located beneath the instrument panel and select the vehicle to be tested from the WDS or equivalent Tester menu. If the WDS or equivalent Tester does not communicate with the vehicle: check that the program card is correctly installed. check the connections to the vehicle. check that the ignition switch is in the RUN position.
- If the WDS or equivalent Tester still does not communicate with the vehicle, refer to «PINPOINT TEST 1: NO COMMUNICATION WITH THE GENERIC ELECTRONIC MODULE (GEM)»(ref-178558-S10148966922005061700000) .
- Refer to the «GEM DIAGNOSTIC TROUBLE CODE (DTC) INDEX»(ref-178558-S01280521972005061700000) .
