Circuit Description

WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2008 Suzuki Reno, 2008 Suzuki Forenza, 2007 Suzuki Reno, 2007 Suzuki Forenza, and 2006 Suzuki Reno. However, it is still accessible from the selected car via links, so may be relevant.

The brake switch is used to indicate brake pedal status to the Transaxle Control Module (TCM). The brake switch is a normally open switch. Applying the brake pedal closes the switch, supplying voltage to the TCM. Releasing the brake pedal interrupts voltage to the TCM.

NOTE:

If the brake pedal was applied prior to or during the connection of the scan tool to the vehicle, P0703 will be disappeared. If the system is operating normally, the code will then be deleted once the brake pedal is applied with the scan tool connected.

This DTC is stored at start-up. If the TCM receives a brake switch signal after start-up, the DTC will be stored in memory.
