Automatic Door Lock System

For complete testing of the automatic door lock systems, refer to the proper Body Diagnostic Procedures.

NOTE: The pinion factor must be set for all new transmission control modules. If the pinion factor is not set or if it is set incorrectly, any speed-related accessories will not operate or will operate inaccurately. This includes the speedometer, speed control, rolling door locks, and other devices that are operated by the powertrain and body control modules. For instructions on setting the pinion factor, see the appropriate transmission diagnostic procedures or the service procedures.
