Selector lever position sensor - starting interlock switch
| Selector lever position sensor - starting interlock switch |
On cars with automatic transmission, the starting interlock switch (77) is integrated with the gear selector position sensor.
Pins 1 and 5 of the switch (77) are used to control the starting relay.
Connector pin 1 is supplied with battery voltage (B+) from fuse 36. On cars with an anti-theft alarm, current is supplied via the anti-theft alarm control module.
In the P and N positions, switch 77 is closed and battery voltage (B+) is supplied to the starting relay.
In all other gear positions the starting interlock switch is open and no current is supplied to the starting relay.
