3 . Check ABS/ESP_CAN communication harness
(a) Ignition switch: OFF.
(b) Disconnect the battery negative cable.
(c) Disconnect connector A006 of ABS/ESP.

04 (d) Use a multimeter to measure the resistance
between the pin 14 and 26 of ABS/ESP
connector A006.

Is the inspection result normal?

YES>To step 4.
NO> Repair or replace harness or connector.

4 . Replace ABS/ESP

(a) Replace ABS/ESP.
(b) Use a diagnostic apparatus to perform DTC verification procedures.
(c) Implement the steps to read sensor data stream.
(d) Check whether DTC exists and the data is normal.
