ABS/TCS/Vdc

VDC OFF SWITCH





- Turn off the ignition switch, and disconnect the VDC OFF switch connector Me, and check the continuity between terminals 1 (L/Y) and 2.

1 - 2: Continuity should exist when pushing the switch.
Continuity should not exist when releasing the switch.

ABS MOTOR RELAY AND ACTUATOR RELAY


- Turn off the ignition switch and disconnect the VDC/TCS/ABS relay box connector E47, E48, E222.








- Apply a voltage of 12V between the ABS motor relay terminal 8 (G/W) and the actuator relay terminal 7 (Y/R) and then check the continuity between the following terminals.

VDC/TCS/ABS ACTUATOR
Actuator Operation Inspection





1. Turn the ignition switch ON, apply a voltage of 12 Volts between the relay box terminal 5 and 8, use an oscilloscope to measure the motor voltage at this time (between terminal 11 and the ground), and check the motor reverse voltage occurrence time when operation is stopped.
Motor counter-electromotive force duration: 0.1 second or more

CAUTION:
- The above check should be performed after motor relay unit inspection to make sure relay operates normally.
- To prevent overheating, do not drive actuator motor more than 4 seconds.
- The motor reverse voltage occurrence time is standard when the battery voltage is 12V and the air temperature is 20°C (68°F), and this time is a little shorter when the battery voltage is low or the air temperature is low.
