INSPECTION PROCEDURE

PROCEDURE


  1. CHECK HARNESS AND CONNECTOR (TRANSMISSION CONTROL ECU - DLC3)


    1. Disconnect the A27 transmission control ECU connector.

    2. Measure the resistance according to the value(s) in the table below.

      Standard Resistance
      Tester Connection Condition Specified Condition
      A27-25 (DG) - C16-13 (TC) Always Below 1 Ω

    NG

    REPAIR OR REPLACE HARNESS OR CONNECTOR

    OK

  2. CHECK HARNESS AND CONNECTOR (TC OF DLC3 - BODY GROUND)


    1. Measure the resistance according to the value(s) in the table below.
