After exhausting the brake light switch avenue, I need help with these two codes.
Summary of work thus far.
My ABS/BAS/ESP lights came on as I was cruising down the highway. Sunny day, no braking involved. Just out of no where. Cruise control works. All brake lights and turn signals work.
Replaced brake light switch twice with units from the dealer, hoping the first one was defective. Adjusted BLS plunger to every single depth (no joke).
Replaced battery with brand new one, since the start up voltage was below 11V.
Alternator checks fine.
Codes read from Aamco by unknown machine.
Codes are C1200: Stop Light Switch Open/Shorted/Implausible
C1504: BAS light, play in steering column causes steering angle sensor to lose memory
No other codes are thrown.
The five wires leading into the BLS look brand new. I did not see any breaks in the wires.
Every single fuse in car is good, under the hood, under the backseat and by the driver door.
With steel wool, I cleaned the connection of the negative jumper to the car chassis as well as the metal where the jumper would connect.
Thank you in advance.
