Diagnostic Procedure
Current data inspection
1.

Monitor "Vehicle Speed Sensor" current data after engine warming up.

■ Reference current data

caution

This current data is nothing but an example at certain condition. Thus, the real current data could be different from this example.

2.

Is "Vehicle Speed Sensor" current data normal?

▶ Go to "Ignition coil circuit inspection" procedure.

▶ Go to "ETC system inspection" procedure.

▶ Go to "Damper clutch inspection" procedure.

▶ Go to "ABS current data inspection" procedure as below.

☞ If vehicle speed sensor current data is abnormal, Inspect ABS system. Because wheel sensor signal input to ABS module and ABS module sends this signal to ECM (PCM).

ABS current data inspection
3.

Monitor "Vehicle Speed Sensor" current data in the ABS system.

4.

If ABS DTC is displayed while driving on lift, erase DTC by using GDS.

■ Reference current data

caution

This current data is nothing but an example at certain condition. Thus, the real current data could be different from this example.

5.

Is "Vehicle Speed Sensor" current data normal?

▶ Repair open/poor connection between ECM harness connector and ABS ECM harness connector.

▶ Repair or replace the wheel speed sensor.

▶ Repair or replace the ABS ECM.
