Inspection Procedures (Without Abs)
- CHECK DTC RELATING TO FRONT RIGHT WSS OF ABS
- Using the Hi-Scan (Pro), check any other DTC.
Is DTC relating to front right wheel speed sensor of ABS?
No: Go to next
Yes: Do all repairs associated with those codes.
- CHECK ABS CONTROL MODULE AND ECM CONNECTORS
- Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or damage.
Are all connectors good?
Yes: Go to next
No: Repair or replace it.
- CHECK WHEEL SPEED SENSOR
- Check resistance of wheel speed sensor.
- Resistance: 1275~1495ohm
Is resistance normal?
Yes: Go to next
No: Replace it.
- CHECK FOR OPEN IN HARNESS
- Turn ignition switch to OFF and disconnect ECM and WSS connectors.
- Measure resistance between terminal 1 of WSS harness connector and terminal 18 of ECM harness connector.
- Measure resistance between terminal 2 of WSS harness connector and terminal 17 of ECM harness connector.

- Specification: below 1ohm
Does resistance indicate continuity?
Yes: Go to next
No: Repair open in harness.
- CHECK FOR SHORT TO POWER IN HARNESS
- Turn ignition switch to ON.
- Measure voltage between terminal 1 of WSS harness connector and chassis ground.
- Measure voltage between terminal 2 of WSS harness connector and chassis ground.

- Specifications: below 0.5 V
Is voltage within specification?
Yes: Go to next
No: Replace it.
- CHECK FOR SHORT TO GROUND IN HARNESS
- Turn ignition switch to OFF.
- Measure resistance between terminal 1 of WSS harness connector and chassis ground.
- Measure resistance between terminal 2 of WSS harness connector and chassis ground.
