8B-71 Air Bag System:
DTC Will Set when
Side-sensor abnormal signal is detected by SDM.
Flow Test Description
Step 1: Check for open circuit in forward sensor circuit.
Step 2: Check for short circuit between forward sensor circuit and ground.
Step 3: Check for short circuit between forward sensor circuit and power supply circuit.
Step 4: Check if malfunction is in forward sensor.
DTC Troubleshooting
Step
1 1) Disconnect side-sensor connector "L35" or "L11".
2) Disconnect SDM connector "L33".
3) Check proper connection to SDM connector at terminals
"L33-13" and "L33-14" or "L33-15" and "L33-16".
4) Check proper connection to side-sensor connector at
terminals "L35-1" and "L35-2" or "L11-1" and "L11-2".
5) Using service wire (1), connect "L35-1" and "L35-2"
terminal (for DTC B1087) or "L11-1" and "L11-2" terminal
(for DTC B1097) of side-sensor connector.
6) Measure resistance between terminals "L33-13" and
"L33-14" (for DTC B1087) or terminals "L33-15" and
"L33-16" (for DTC B1097) of SDM connector.

in "WHT/RED" circuit or
"LT GRN/BLK" circuit.
For DTC B1097: High
resistance or open wire
in "WHT/GRN" circuit or
"LT GRN" circuit.
For DTC B1087: "WHT/
RED" circuit or "LT
GRN/BLK" circuit
shorted to ground.
