B1087

DTC B1087 / B1097: Left / Right Side-Sensor Communication Error

Wiring Diagram










DTC Will be Set when

Side-sensor abnormal signal is detected by SDM.

Flow Test Description

Step 2: Check for open circuit in forward sensor circuit.

Step 3: Check for short circuit between forward sensor circuit and ground.

Step 4: Check for short circuit between forward sensor circuit and power supply circuit.

Step 5: Check if malfunction is in forward sensor.

DTC Troubleshooting

1.
Was "Air Bag Diagnostic System Check" performed?
YES -
Go to Step 2.
NO -
Go to Air Bag Diagnostic System Check Air Bag Diagnostic System Check:Except Advanced Air Bag.

2. Disconnect side-sensor connector "L35" or "L11".
Disconnect SDM connector "L33".
Check proper connection to SDM connector at terminals "L33-13" and "L33-14" or "L33-15" and "L33-16".
Check proper connection to side-sensor connector at terminals "L35-1" and "L35-2" or "L11-1" and "L11-2".
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.
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.
Special Tool

(A): 09932-76010





Is each measured resistance 1 ohms or less?
YES -
Go to Step 3.
NO -
For DTC B1087: High resistance or open wire 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.

3.
Measure resistance between "L33-13" terminal and body ground, and "L33-14" terminal and body ground (for DTC B1087) or between "L33-15" terminal and body ground, and "L33-16" terminal and body ground (for DTC B1097).
Special Tool

(A): 09932-76010





Is each measured resistance infinity?
YES -
Go to Step 4.
NO -
For DTC B1087: "WHT/RED" circuit or "LT GRN/BLK" circuit shorted to ground.
For DTC B1087: "WHT/GRN" circuit or "LT GRN" circuit shorted to ground.

4.
Check side-sensor referring to Side-Sensor Inspection Side-Sensor Inspection:Except Advanced Air Bag.

Is it in good condition?
YES -
Substitute a known-good SDM and recheck.
NO -
Replace side-sensor referring to Side-Sensor Removal and Installation Side-Sensor Removal and Installation:Except Advanced Air Bag. If DTC still exists, substitute a known-good SDM and recheck.

NOTE:

Upon completion of inspection and repair work, perform the following items.

- Reconnect all air bag system components and ensure all components are properly mounted.
- Clear DTCs referring to DTC Clearance DTC Clearance:Except Advanced Air Bag
, if any.
- Repeat Air Bag Diagnostic System Check Air Bag Diagnostic System Check:Except Advanced Air Bag
to confirm that the trouble has been corrected.
