Stop (Brake) Lamp Switch

WARNING: This page is about a different car, the 2002 Volvo C70, 2001 Volvo C70, 2000 Volvo C70, 1999 Volvo C70, and 1998 Volvo C70. However, it is still accessible from the selected car via links, so may be relevant.

The engine control module (ECM) transmits a signal on the Control area network (CAN) indicating whether the stop (brake) lamp switch is activated or not. The transmission control module (TCM) uses the signal to disconnect the lock-up function when braking in order to avoid jolts in the transmission.

OFF = Stop (brake) lamp switch unaffected

ON = Stop (brake) lamp switch affected
