Battery Control Module: Installation

WARNING: This page is about a different variant/trim than selected.

WARNING: The hybrid system includes a high voltage circuit. Mishandling could cause accidents such as electric shock or leak. Refer to PRECAUTION/WARNING>Warning (HYBRID SYSTEM) .

CAUTION: Airbag system satellite safing sensor is located under the front center of the rear seat cushion. Be careful not to apply strong impact to the sensor when working with the rear seat cushion removed.

Install the bracket - battery ECU.

WARNING:

Be sure to wear insulated gloves and use insulated tools.
Be sure to use an insulating sheet at locations other than the work location.

CAUTION: If the battery ECU was dropped or subjected to a strong impact, replace it with a new one.

Temporarily assemble the bracket - battery ECU to the battery ECU while leaving a clearance for adjusting the position.

Install the temporarily assembled battery ECU assembly to the HV battery.
CAUTION: Do not connect the connector.

Tightening torque:

7.5 N.m (0.8 kgf-m, 5.5 ft-lb)

With the condition of step (2), further tighten the bolts for temporarily assembling the bracket - battery ECU, so that the bracket doesn't move.

CAUTION: The torque of further tightening should not exceed the specified torque (7.5 N.m (0.8 kgf-m, 5.5 ft-lb)) for the final tightening.

NOTE: Overall length of an insulated spanner is 108 mm (4.25 in), so the force applied to the end of spanner handle becomes less than approx. 0.8 N (0.08 kgf, 0.18 lb).

Remove the battery ECU assembly from the HV battery.
Perform the final tightening of the bracket - battery ECU.
Tightening torque:

7.5 N.m (0.8 kgf-m, 5.5 ft-lb)

Install the battery ECU assembly.
WARNING:
- Be sure to wear insulated gloves and use insulated tools.
- Be sure to use an insulating sheet at locations other than the work location
CAUTION:
- If the battery ECU was dropped or subjected to a strong impact, replace it with a new one.
- Make sure the connector is connected securely.
