Traction Control Button Issues
Pressing the traction control button does nothing
Holding down the button for 5/10/15/20 seconds does nothing
Diagnostics:
- [GOOD] Checked continuity from BCM pin D15 to traction control switch pin (BRN/WHT)
- [GOOD] Checked continuity from traction control switch pin (BLK) to drive kick panel ground
- KOEO Checked voltage at switch pin at traction control (BRN/WHT) 0 volts (I don't know what voltage should be read here if any)
- Switched traction control button to another used button (claimed tested but not known if good switch)
- When unplugging the BCM connector and replugging the car cycles between the trac control settings
- No codes relating to TC
Things to do:
- Get a known working switch from another car and test
Questions:
- Should I be reading voltage at the traction control pin
- What else should I be looking for
Thanks everyone for your input!
