Enhanced Testing

P0703 - Stop Lamp Switch (Brake SW): Short (B+)






General Description
The HIVEC Automatic Transmission's function, of intelligence control, is based on the Fuzzy Control System. The Fuzzy Control System determines optimal gear positions as related to driver's intention and current driving conditions. The Brake Switch provides important information by deciding whether the vehicle is decelerating by the depression of the brake pedal, or if the speed is decreasing because the vehicle is running on the uphill.

DTC Description
The TCM (PCM) sets this code if a Brake Switch signal is input continuously, for an extended period of time, when the vehicle is supposed to be running (moving).
