Lost Communication with Door Side Airbag Sensor LH |
DESCRIPTION
for DTC B1695/16:
The side airbag sensor LH consists of the safing sensor, the diagnostic circuit, the lateral deceleration sensor, etc.
If the center airbag sensor assembly receives signals from the lateral deceleration sensor, it determines whether the SRS should be activated.
DTC B1695/16 is recorded when a malfunction is detected in the side airbag sensor LH circuit.
for DTC B1697/82:
The circuit for the side collision sensor LH (to determine deployment of the front seat side airbag assembly LH and curtain shield airbag assembly LH) is composed of the center airbag sensor assembly, side airbag sensor LH and rear airbag sensor LH.
The side airbag sensor LH and rear airbag sensor LH detect impacts to the vehicle and send signals to the center airbag sensor assembly to determine if the airbag should be deployed.
DTC B1697/82 is recorded when a malfunction is detected in the circuit for the side collision sensor LH (to determine deployment of the front seat side airbag assembly LH and curtain shield airbag assembly LH).

1. |
CHECK SIDE AIRBAG SENSOR LH |
(a) Turn the ignition switch off.
(b) Disconnect the negative (-) terminal cable from the battery, and wait for at least 90 seconds.
(c) Interchange the side airbag sensor LH with RH and connect the connectors to them.
(d) Connect the negative (-) terminal cable to the battery, and wait for at least 2 seconds.
(e) Turn the ignition switch to ON, and wait for at least 60 seconds.
(f) Clear the DTCs stored in the memory (See page
![2016 - 2020 MY Sienna [12/2015 - ]; SUPPLEMENTAL RESTRAINT SYSTEMS: AIRBAG SYSTEM: DTC CHECK / CLEAR](/t3Portal/stylegraphics/info.gif)
).
(g) Turn the ignition switch off.
(h) Turn the ignition switch to ON, and wait for at least 60 seconds.
(i) Check for DTCs (See page
).
