    1. Disconnect the 2A, 2D, 2L and 2H driver side junction block assembly connectors.

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

      Terminal No. (Symbol) Wiring Color Terminal Description Condition Specified Condition
      2D-9 (GND) - Body ground W-B - Body ground Ground Always Below 1 Ω
      2D-18 (GND) - Body ground W-B - Body ground Ground Always Below 1 Ω
      2H-4 (ALTB) - Body ground LG - Body ground Battery power supply Always 11 to 14 V
