i did not mean to say constant clicking. Just a few inconsistent slow clicking sounds. nothing consistent. nothing i can make happenGood verification. This indicates that fuse M1 in the TIPM is good. When the brake pedal is depressed, the brake light plunger extends. Terminal 5 power from fuse M1 is connected to terminal 6 and onto the rear center high mounted stop lamp and onto a connector at the TIPM.
And I believe you indicated that when the brake pedal is depressed, the left rear and right rear brake lamps turn on? Is this correct?
If YES then the TIPM is receiving the proper signal to activate the brake lamps and the circuit through the brake light switch for controlling the brake lamps is functioning properly. So that circuit can be eliminated as a source of the issue.
Since the adoption of drive by wire (electronic throttle control; no mechanical cable connection between accelerator pedal and throttle butterfly) the cruise control hardware has been simplified. Since you are able to drive the vehicle and the throttle works correctly, you know that the PCM is able to control the stepper motor at the throttle body and open and close the throttle butterfly valve.
Because the PCM has detected a brake sense signal circuit 1 problem, it is disabling the cruise control feature for safety reasons. If the P0572 code can be eliminated then the cruise control function will return.
In a recent post you mentioned hearing a constant clicking sound coming from the area of the transmission selector lever. I believe that the wireless control module is receiving false signals and applying a constant duty cycle to that transmission shift lever unlock solenoid. That is it is rapidly energizing and de-energizing the solenoid. Maybe the wireless control module is recognizing the rapid cycling and disabling cycling control to protect the solenoid? This solenoid is probably designed for intermittent duty and not constant duty. (This is a BIG guess!)
Next step is to check the ground terminal at the brake light switch. I believe it is terminal 2. Look for a wire that is black with red tracer or solid black. I have found some inconsistencies in wiring diagrams with wire colors so I am not sure. But I believe the ground wire is black with red tracer. Use a 12 volt test lamp and touch one lead to 12 volt power and the other to terminal 2 (black / red tracer wire). The test lamp bulb should illuminate brightly. If NO illumination there is an open ground circuit problem. If the bulb is dim then there is excessive resistance in the circuit to ground location G300. Report back.
Does anyone know where ground G300 is located? My resources are limited and I am not sure. Is G300 grounded on the floor under the driver's feet? Grounded to the left cowl? Grounded to the steering column? If there is a poor ground / no ground at the brake light switch terminal 2 then the location will need to be determined.
