Part Description: ATX Shifter
Issue
Description:
Prior to removing (or disconnecting) the automatic transmission shifter knob, for any
service to the shifter or for console removal, disconnect and isolate the battery
negative cable. Wait two minutes for the system capacitor to discharge before
further service. This will prevent a P1C86-14 DTC being stored in the electronic shift
module (ESM). Failure to disconnect the battery before servicing the shifter may
cause the P1C86-14 DTC to be set again. Clear the code before replacing the
shifter. In the event a P1C86-14 DTC persist after following the above procedure,
refer to 28 - DTC-Based Diagnostics, in the service manual.
