I have a D6m ser#3wno1441 The operator said he was going forwarder pushed clutch brake peddle shifted into reverse Machine stopped won’t move We found a mouse had chewed the grey wire from the break switch Fixed the wire still won’t move Replaced all solenoids for the brakes and steering and the priority valve Still nothing Bought a click box cleared a lot of codes with it there are two active codes that are on now they are 113- 0691.07 0692.07 Any ideas thanks
G'day and welcome. Attached are the trouvbleshooting procedures for 691-07 and 692-07. See where they take you. You will need to check pressures on the transmission. If you need specifications or a procedure please ask. Something in the back of my mind tells me that either the service brake pedal position sensor or the pedal travel limit switch can be inoperative or defective and NOT set a Diagnostic Code. I will send you an electrical schematic so that you can test the function of both the aforementioned so keep an eye on your messages. You will need a multimeter capable of measuring Duty Cycle because the pedal position sensor is a PWM type.
Some snippets of information. 1. Brake pedal switch contacts should be OPEN with the pedal in the UP position. The switch contacts should close only when the brake pedal is pressed down to almost the bottom of its travel. This switch effectively signals the ECM to dump the parking brake pressure and applies the PB when the pedal is pressed right down. If the switch contacts are permanently closed the park brake will always be on. 2. Service brake pedal position sensor duty cycle should be in the range of 8% to 37% with the pedal in the UP position. With the pedal pressed fully down the duty cycle should be a minimum of 61%.
