HINT:
If the tire pressure warning light blinks continuously, a ground short in the wiring of terminal TC of the DLC3 or an internal ground short in each ECU is suspected.

INSPECTION PROCEDURE

1.CHECK CAN COMMUNICATION LINE

  1. Turn the engine switch off.

  1. Connect the GTS to the DLC3.

  1. Turn the engine switch on (IG) and turn the GTS on.

  1. Enter the following menus: "CAN Bus Check" from the "System Select" screen.

  1. Check the CAN communication system (for LHD: Click here, for RHD: Click here).

    OK:
    The CAN communication system is normal.

2.CHECK HARNESS AND CONNECTOR (DLC3 - ECM)

  1. Disconnect the ECM A38*1, A52*2 connector.

    1. *1: for LHD
    2. *2: for RHD

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

    Standard Resistance:

    for LHD
    Tester Connection
    		Condition
    		Specified Condition
    E22-13 (TC) - A38-16*1, 27*2(TC)
    		Always
    		Below 1 Ω
    E22-13 (TC) or A38-16*1, 27*2(TC) - Body ground
    		Always
    		10 kΩ or higher
    E22-4 (CG) - Body ground
    		Always
    		Below 1 Ω
    1. *1: for 1UR-FE
    2. *2: for 1VD-FTV

    Standard Resistance:

    for RHD
    Tester Connection
    		Condition
    		Specified Condition
    E22-13 (TC) - A52-27 (TC)
    		Always
    		Below 1 Ω
    E22-13 (TC) or A52-27 (TC) - Body ground
    		Always
    		10 kΩ or higher
    E22-4 (CG) - Body ground
    		Always
    		Below 1 Ω
