Parasitic Draw Check 1 (Check Each BB-CAN Unit)

Test Procedure 

• Preparation
• • -

    Short the BB-CAN_H line to BB-CAN_L line with a jumper wire while the test leads are connected.

• Procedure
• • -

    Turn the vehicle to the ON mode and then the OFF (LOCK) mode.

  • -

    Get out of the vehicle and close all the doors.

  • -

    Wait for at least 40 seconds.

  • -

    Measure the parasitic draw.

Results 

When the parasitic draw is 27.0 mA or less, disconnect the control units from the BB-CAN circuit one at a time, then measure the parasitic draw. Do the input test for the control unit that reduced the parasitic draw to 27.0 mA or less when disconnected.
