Shift lock relay

Shift lock relay


The shift lock function mechanically locks the selector lever in position P. The lock is released by pressing down the brake pedal.

The shift-lock relay and its lifting magnet generate the SHIFT-LOCK function.

The relay is connected in parallel with gear selector position sensor contacts B and C to pins 10 and 28 of the transmission control module.

The shift lock relay is located in the main fuse box under the main instrument unit. Due to the parallel connection above, a faulty gear selector position sensor and shift lock relay will give the same malfunction on pins 10 and 28 and consequently the same DTC (P0705).

The lifting magnet is fitted in the selector lever's console and controls the ability of the selector lever to move. Gear selector position sensor contacts B and C indicate gear position P when they are both “0” (in all other gear positions either B or C is “1”). In addition, input R must also be “0” for the shift-lock relay to release. This happens when the brake pedal is depressed. When the relay releases, the lifting magnet becomes passive and the selector lever is no longer mechanically locked.

The shift-lock function can be disconnected by removing fuse 9.
