Circuit Description

An electronic gear indicator display is used. 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. PCM uses the combination of the switch patterns to determine the gear selected by the driver. This information is then sent by serial data to the IPC for gear indicator display. This test compares the gear indicated by the transaxle range switch to the gear selected from the transmission fluid pressure manual valve position switch. If gear indicated is not the same for both, DTC will set.
