Toyota CH-R Service Manual: Lost communication with Side Airbag Sensor LH (B1627/82,B1628/82,B1637/82,B1638/82,B1647/82,B1648/82,B167B/82,B167C/82)

Toyota CH-R Service Manual / Supplemental Restraint Systems / Airbag System / Lost communication with Side Airbag Sensor LH (B1627/82,B1628/82,B1637/82,B1638/82,B1647/82,B1648/82,B167B/82,B167C/82)

DESCRIPTION

The side collision sensor LH circuit (bus 1) consists of the airbag sensor assembly, door side airbag sensor LH, No. 1 side airbag sensor LH and No. 2 side airbag sensor LH.

The door side airbag sensor LH, No. 1 side airbag sensor LH and No. 2 side airbag sensor LH detect impacts to the vehicle and send signals to the airbag sensor assembly to determine if the airbags and pretensioners should be deployed.

These DTCs are stored when a malfunction is detected in the side collision sensor LH circuit (bus 1).

DTC No.

CHECK CONNECTORS

(a) Turn the ignition switch off.

(b) Disconnect the cable from the negative (-) battery terminal.

CAUTION:

Wait at least 90 seconds after disconnecting the cable from the negative (-) battery terminal to disable the SRS system.

(c) Check that the connectors are properly connected to the airbag sensor assembly, No. 1 side airbag sensor LH, No. 2 side airbag sensor LH and door side airbag sensor LH. Also check that the connectors that link the floor wire and front door wire LH are properly connected.

OK:

The connectors are properly connected.

HINT:

If the connectors are not properly connected, reconnect the connectors and proceed to the next inspection.

(d) Disconnect the connectors from the airbag sensor assembly, No. 1 side airbag sensor LH, No. 2 side airbag sensor LH and door side airbag sensor LH. Also disconnect the connectors that link the floor wire and front door wire LH.

(e) Check that the terminals of the connectors are not deformed or damaged.
