C060D Left Park Brake Actuator Control Circuit High

Check engine lightUsually off
EmissionsNot relevant
Drive cycleNot required
Limp modePossible

Here one of the two left motor leads reads high: it is shorted to battery voltage, or touches another live wire, so the low side of the bridge cannot pull it down. A bridge driver such as the DRV8873-Q1 detects an output shorted to the battery and disables the stage to protect itself. The motor sits in the rear caliper, where ZF's design drives a spindle through a gearbox, so its leads run along the moving suspension and through a weather-exposed plug. Hyundai's left-side motor short/open bulletin (code C2416) and GM's rear-circuit resistance check in PIT5662A show the same weak spots. No maker publishes C060D. The left side stays as it was, and the driver gets a park brake warning.

Likely causes

Motor lead shorted to a battery-fed wire
Moisture bridging pins in the caliper connector
Failed driver stage in the brake control module

Symptoms

  • Park brake warning lamp on
  • Left rear brake does not respond to the switch
  • Electronic pad change mode cannot be entered
