DTC Troubleshooting
Step
1 Was "Air Bag Diagnostic System Check Flow" performed?
2 Side impact-sensor circuit check
1) Disconnect applicable side impact-sensor connector
"L35" or "L36".
2) Disconnect SDM connector "L04".
3) Check for proper connection to SDM connector at
terminals "L04-46" and "L04-47" (for DTC B1084) or
terminals "L04-44" and "L04-45" (for DTC B1094).
4) Check for proper connection to applicable side impact-
sensor connector at terminals in connector "L35" or
"L36".
5) Measure resistance between "L04-46" and "L36-2"
terminals, between "L04-47" and "L36-1" terminals (for
DTC B1084).
6) Measure resistance between "L04-45" and "L35-2"
terminals, between "L04-44" and "L35-2" terminals (for
DTC B1094).
