(b) Disconnect the cable from the negative (-) battery terminal.
NOTICE:
Wait at least 90 seconds after disconnecting the cable from the negative (-) battery terminal to disable the SRS system.
(c) Interchange the rear airbag sensor RH with LH and connect the connectors to them.
(d) Connect the cable to the negative (-) battery terminal.
(e) Turn the engine switch on (IG), and wait for at least 60 seconds.
(f) Clear the DTCs stored in the the memory See: Restraints and Safety Systems/Air Bag Systems/Testing and Inspection/Reading and
Clearing Diagnostic Trouble Codes/DTC Check / Clear.
(g) Turn the engine switch off.
(h) Turn the engine switch on (IG), and wait for at least 60 seconds.

SUPPLEMENTAL RESTRAINT SYSTEMS: AIRBAG SYSTEM: B1627/82,B1628/82,B1637/82,B1638/82,B1647/82,B1648/82: Lost
communication with Side Airbag Sensor LH
B1648/82 - Side Satellite Sensor Bus LH Initialization Incomplete
DESCRIPTION
The side collision sensor LH circuit (to determine deployment of the front seat side airbag assembly LH, rear 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.
Theses DTCs are recorded when a malfunction is detected for the side collision sensor LH circuit (to determine deployment of the front seat side
airbag assembly LH, rear seat side airbag assembly LH and curtain shield airbag assembly LH).
