      (to Electric Parking Brake ECU)

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

      Tech Tips

      Voltage cannot be measured with the connector connected to the electric parking brake ECU as the connector is watertight.

      Terminal No. (Symbol) Wiring Color Terminal Description Condition Specified Condition
      I1-13 (+B) - Body ground B - Body ground +B power supply Always 11 to 14 V
      I1-19 (IG) - Body ground G - Body ground IG power supply Ignition switch ON 11 to 14 V
      I1-24 (GND1) - Body ground W-B - Body ground Electric parking brake ECU ground Always Below 1 Ω
