Monitor Scan Tool Data
- With vehicle raised on a lift, start the engine and place transaxle in Drive. Let vehicle idle and verify speedometer indicates approx. 10km/h or more (6mph or more) on the instrument cluster.
- Connect Scantool and select ABS system.
- Monitor the "WHEEL SPD SENSOR-FR" parameter on the current data list.
Specification: 10km/h or more (6mph or more)
- Is value within the specification?
YES : --> Wheel speed sensor is OK. Go to "SIGNAL CIRCUIT INSPECTION [WITH ABS] " procedure.
NO : -->
--> Check for open or short circuit between wheel speed sensor (FR) and ABS (or ESP) control module.
--> If problems are found, repair as necessary and go to "VERIFICATION OF VEHICLE REPAIR " procedure
--> If OK, Check wheel speed sensor (FR) as follow :
- Gap between ABS sensor and trigger wheel (Air gap: 0.3-1.1 mm (0.011 ~ 0.043 in))
- Trigger wheel condition
- Sensor resistance: Approx. 1,300~1,500Ω at 20°C (68°F)
--> Replace wheel speed sensor as necessary and go to "VERIFICATION OF VEHICLE REPAIR " procedure.
