ABS Vehicle
1. Connect scantool to Data Link Connector (DLC).
2. Warm up the engine to normal operating temperature.
3. Monitor the "VSS" parameters on the scantool. (ENG. Control)
4. Monitor the "WHEEL SPEED SENSOR-FR" parameter on the Scantool. (ABS Control)




5. Are the parameters displayed correctly?
YES
1) Fault is intermittent caused by poor contact in the sensor's and/or ECM's connector or was repaired and ECM memory was not cleared. Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or damage. Repair or replace as necessary and go to "Verification of vehicle Repair" procedure.
NO
1) If both vehicle speed signal from ECM and Wheel Speed Signal from ABS on current data are not displayed refer to DTC C1203 "Wheel speed sensor front -RH open/short" in ABS DTC section.
2) If the Wheel Speed Signal from ABS is O.K but Vehicle Speed Signal from ECM on current data is not properly displayed, go to "Inspection and Repair" procedure.
Non-ABS Vehicle
1. Connect scantool to Data Link Connector (DLC).
2. Warm up the engine to normal operating temperature.
3. Monitor the "VSS" parameters on the scantool.
