Circuit Description

Vehicle uses an electronic gear indicator display. There are 4 inputs which are switches to ground that each have a unique switch pattern. All 4 of these inputs are housed and operate together in the transaxle range switch. The PCM uses the combination of the switch patterns to determine the gear selected by the vehicle operator. This information is then sent by serial data to the IPC for gear indicator display.

This test monitors the transaxle range switch for false inputs. DTC will set if the transaxle range switch is indicating a gear that the PCM does not recognize or the transaxle range switch input does not match the input of the transaxle pressure switch.
