Inspection Procedure

NOTE: When replacing the ABS and TRACTION actuator assembly, perform zero point calibration (See CALIBRATION  ).
  1. INSPECT DLC3 
    1. Turn the ignition switch to the ON position.
    2. Measure the voltage according to the value(s) in the table below.

      Standard voltage
