  1. Turn the engine switch off.

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

    Standard Voltage:
    Tester Connection
    		Switch Condition
    		Specified Condition
    E22-13 (TC) - E22-4 (CG)
    		Engine switch on (IG)
    		11 to 14 V

5.CHECK HARNESS AND CONNECTOR (TC of DLC3 - ECM)

  1. Turn the engine switch off.

  1. Disconnect the A38*1 or A52*2 ECM 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 1UR-FE
    Tester Connection
    		Condition
    		Specified Condition
    E22-13 (TC) - A38-16 (TC)*1
    E22-13 (TC) - A52-16 (TC)*2
    		Always
    		Below 1 Ω
    E22-13 (TC) or A38-16 (TC)*1 - Body ground
    E22-13 (TC) or A52-16 (TC)*2 - Body ground
    		Always
    		10 kΩ or higher
    for 1VD-FTV
    Tester Connection
    		Condition
    		Specified Condition
    E22-13 (TC) - A38-27 (TC)*1
    E22-13 (TC) - A52-27 (TC)*2
    		Always
    		Below 1 Ω
    E22-13 (TC) or A38-27 (TC)*1 - Body ground
    E22-13 (TC) or A52-27 (TC)*2 - Body ground
    		Always
    		10 kΩ or higher
    1. *1: for LHD
    2. *2: for RHD
