DESCRIPTION
The TCM detects the ON/OFF status of the parking brake switch. When the parking brake is applied, the parking brake switch turns ON. When the parking brake is released, the switch turns OFF.
When the brake pedal is not depressed with the gear in 1st, 2nd or reverse, the clutch is half-engaged, even if the accelerator pedal is not depressed. As a result, the vehicle can creep slowly like an automatic transaxle vehicle. This assists the vehicle in preparing to move. The take off assist control is canceled while the parking brake switch is ON.
