question on switches on pedals
question on switches on pedals I know which one is the neutral safety switch but what is the switch for when the pedals are all the up there is another white switch. I am switching the pedal assy. to auto and not sure what this one is it depresses when the clutch pedal is all the way up
The top switch actually tells with the clutch is just pressed, and the bottom switch when it's fully depressed. The top switch tells the ECM the clutch is starting to move, so it can anticipate the shift, and control functions like the reverse lockout and CAGS.
CAGS is a combination of VSS,TPS, MAP, MAF, and RPM. If the ECM sees that you are going slow enough and there is a relatively small change in TPS, MAP, MAF and RPM v.s. time then it enables the skip-shift solenoid. If however, you are accelerating quickly it does not enable skip-shift and allows you to select second gear.
The switch at the top is only for turning off cruise control if you press the clutch pedal. That way the ECM knows not to try to increase throttle as the car is slowing down from not having the clutch engaged. If it didn't have the switch the engine would rev up when you pressed the clutch pedal without first turning cruise control off.
