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).

CAUTION / NOTICE / HINT
Note
After turning the ignition switch off, waiting time may be required before disconnecting the cable from the negative (-) battery terminal. Therefore, make sure to read the disconnecting the cable from the negative (-) battery terminal notices before proceeding with work.
PROCEDURE
CHECK CURRENT DTC
Check for current DTCs.
Tech Tips
DTCs indicating communication errors will be changed to DTCs indicating errors in initialization by turning the ignition switch off and then ON again.
Codes other than current DTCs B1627, B1628, B1637, B1638, B1647, B1648, B167B, B167C and 82 may be output at this time, but they are not related to this check.

CHECK CONNECTORS
Turn the ignition switch off.
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.
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. |
Tech Tips
If the connectors are not properly connected, reconnect the connectors and proceed to the next inspection.
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.
Check that the terminals of the connectors are not deformed or damaged.
