Creep Aid Control
The Creep Aid System prevents the vehicle from moving backwards when the vehicle starts off on an ascending slope after the brake pedal is released.
When the vehicle comes to a stop, the engine is stopped by the auto-stop system under certain conditions. The start clutch is released because the ATF pump does not operate when the engine is stopped.
With the auto-stop system, when the vehicle comes to a stop with the brakes applied on an ascending slope, the TCM turns the creep-aid system solenoid valves A and B ON. This maintains the brake pressure, applied during the stop, to the brakes. When the engine restarts, the TCM turns the creep-aid system solenoid valves A and B OFF releasing the brake system pressure, allowing the vehicle to creep.
