| Description of the problem | The hill start assist malfunctions constantly, this can stall the engine when starting out in traffic and cause excessive ware on the brakes and clutch. There are 2 switches that tell the computer when the clutch pedal is pressed. One when you first start to press in the clutch and another that tells the computer when the clutch is pressed in all the way. The hill start assist is programmed to use the switch that tells the computer when you first start to press in the clutch instead of the switch that tells the computer when the clutch pedal is fully pressed. This causes the brakes to stay locked up even after the clutch is fully engaged when starting on a hill. The computer needs to be reprogrammed to release the brakes as soon as you start to release the clutch petal before the clutch fully engages. The hill start assist should use the same switch that tells the computer the clutch is fully pressed which is the same switch that is used to prevent the vehicle from starting in gear and not the switch that tells the computer when the pedal is lightly pressed which is the switch that turns off the cruise control. |
