CHECK OUTPUT SIGNAL OF BODY INTEGRATED UNIT.

1) Lift up the vehicle.

2) Start the engine.

3) Shift the select lever to “D” range and slowly increase vehicle speed to more than 20 km/h (12 MPH).

NOTE:

A speed difference between front and rear wheels causes the ABS warning light or the VDC warning light to illuminate, but this does not indicate a malfunction. If the warning light is illuminated, clear the ABS and VDC memories of the on-board diagnostic system after completing AT control diagnosis.

4) Measure the voltage between body integrated unit and chassis ground.

Connector & terminal

(B279) No. 12 (+) — Chassis ground (−):

QUESTION
Is the voltage less than 1 V?
Yes	No
The circuit is normal. If the ATF temperature warning light is flashing, repair the reverse inhibitor control circuit harnesses or connectors.
