Sensor Output Value Inspection
- Performing the resistance inspection using a tester may cause damage to the ABS wheel-speed sensor internal circuit. Be sure to use the M-MDS to inspect the ABS wheel-speed sensor.
- Switch the ignition to off.
- Connect the M-MDS (IDS) to the DLC-2.
- Select the following PIDs using the M-MDS:
- WSPD_LF
(LF wheel-speed sensor)
- WSPD_RF
(RF wheel-speed sensor)
- WSPD_LF
- Start the engine and drive the vehicle.
- Verify that the display of the M-MDS shows the same value as the speedometer.
- If there is any malfunction, replace the ABS wheel-speed sensor.
