DESCRIPTION
The side collision sensor LH circuit (bus 1) consists of the airbag sensor assembly, door side airbag sensor LH and rear airbag sensor LH.
The door side airbag sensor LH and rear 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 engine 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 engine switch off and then on (IG) again.
Codes other than current DTCs 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 engine 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, door side airbag sensor LH and rear airbag sensor LH. Also check that the connectors that link the No. 2 floor wire and front door wire LH are properly connected.
OK |
