Code 36 - Rear Axle Toothed Wheel Frequency Error: Notes

Toothed wheel generates a voltage pulse as it moves past sensor. EBCM uses these pulses to determine wheel speed. EBCM uses wheel speed sensor signal to calculate vehicle reference speeds and speed, acceleration and slip values for each wheel. These values are used to determine when anti-lock control is needed.

Code 36 will be set if improper speed signals are generated by toothed ring sensor. Some causes are incorrect number of teeth on sensor ring, sensor rings covered with dirt, grease or metallic particles, and damaged toothed sensor ring.

Code 36 may be set while driving if one wheel is detected at least 19 MPH faster or 4 MPH less or greater than remaining wheels for an extended period of time.
