Brake Switch - TCC: Description and Operation
Brake Light Switch
The brake light switch supplies the control module and the shift-lock relay with information.
Depressing the brake pedal will activate the brake light switch and send information to control module pin 26, which will disengage the lock-up function
if the engine speed is below 2000 rpm. Activation puts B+ on pin 26.
The shift-lock function mechanically locks the gear lever in the P position when the engine is being started. Depressing the brake pedal checks the
shift-lock relay and releases the mechanical lock.
