I will buy the gauge and test in the morning but, i found something interesting, maybe you or someone else could tell me if it is something.
With the Genisys Evo running custom datastream and set to focus on the following
1) Brake Pedal Position
2) Brake pedal Press Applied sw
3) Park brake apply sw
I am sitting at idle, gear in park engine warm. Here is the action and the response
1) apply brake pedal, changes from on to off etc, seems to function
2) stays in off position no matter what i do. press the brake, set e-brake, no affect
3) this stays on no matter weather the e-brake is applied or not.
I removed the e-brake switch, seems very simple. I am no electrician but, it appears this ground to body, when the brake is applied the ground is broke and a light goes on. My light stays on. I put an ohm meter across the ground plate and the connector, meter starts at 0.2 with leads crossed, reads same when i touch the ground plate and the connector. when i engage the switch meter goes to OL. seems to me the switch is working. Can anyone tell me, first, why my park brake apply sw stays on, and two would this cause the hard pedal press and little brake power?
Per the Factory test procedure, the parking brake applied is one issue, so iif my switch is lying to the computer, maybe i found a cheap fix, if only the switch were bad.
