DESCRIPTION OF OPERATION
On cars with automatic transmission for certain markets have a SHIFT LOCK function which locks the transmission. This entails the following:
^ The ignition switch must be in the Drive position and the brake pedal depressed before the selector lever can be moved from the P position.
^ The selector lever must be in the P position before the ignition key can be removed from the ignition switch.

When Starting
When the ignition switch is turned to the Start position, operating current is supplied to terminal 86 of the starter interlock relay, causing the relay to operate.

When the brake pedal is then depressed and held in this position, solenoid 439 is connected to ground. As a result, the solenoid no longer locks the P position and the selector lever can be moved.

When Switching Off
When the ignition switch is turned to the OFF position, solenoid 438 in the ignition switch locks the ignition key so that it cannot be removed until the selector lever has been moved to the P position.

Solenoid 438 is grounded when the selector lever is in the P position. As a result, the solenoid no longer locks the ignition key.

IMPORTANT: Due to current consumption, the car must not be left for lengthy periods with the key in the ignition switch and the gear selector lever in any other position except P.

When The Car Is Without Current
When the car is electrically dead (completely without current), it will not be possible to move the selector lever out of the P position. For that reason, be sure not to move the selector lever to the P position if the car is without current.

FAULT DIAGNOSIS HINTS
1. Check the connectors, wiring harness and ground connections.

When Starting
1. Inspect fuse 1 and check that it is supplied with current.
2. Check that current is supplied to starter interlock relay 437 and that the relay operates.
3. Check that current is supplied to the solenoid when the brake pedal is held down.

When Switching Off
1. Inspect fuse 27 and check that it is supplied with current.
2. Check that current is supplied to solenoid 438 when the P position is selected.
