Checking ABS sensor ring

Checking ABS sensor ring

Special tools and workshop equipment required

♦ Sensor gauge for -T10473-

– Remove wheel bearing unit:

♦ Front wheel bearing unit → Running gear, axles, steering; Rep. gr.40; Wheel bearing; Removing and installing wheel bearing unit

♦ Rear wheel bearing unit → Running gear, axles, steering; Rep. gr.42; Wheel bearing, trailing arm; Removing and installing wheel bearing unit

– Use sensor gauge -T10473- -A- to check ABS sensor ring -2- on wheel bearing unit -1- all around.

Test pattern for ABS sensor ring

A - ABS sensor ring is OK

B - ABS sensor ring is defective
