N5 Determine Location of Short Circuit to Ground

- Disconnect rear axle speed sensor.

- Check resistance between sensor connector pins and known good chassis ground.

- Is resistance less than 10k ohms?

YES -- Replace rear axle speed sensor. Go to N12 to verify concern is resolved.

NO -- Sensor is OK. Find and repair short in Circuit 519 (LG/BK) or 523 (R/PK). Go to N12 to verify concern is resolved.
