DTC B0095-87: No Signal From the Right Front Impact Sensor (2014-15)
Special Tools Required:
SRS Inflator Simulator 07SAZ-TB4011A
SRS Simulator Lead L 070AZ-SNAA300
NOTE:
- Before doing this troubleshooting procedure, find out if the vehicle was in a collision. If so, verify that all the required components were replaced with new components of the correct part number and were properly installed. Refer to: SRS Component Replacement/Inspection After Deployment
- Before doing this troubleshooting procedure, review SRS Precautions and Procedures , General Troubleshooting Information , and 12 Volt Battery Terminal Disconnection and Reconnection .
- Before replacing the SRS unit, check the SRS unit software version with the HDS. If the software version is not the latest, update the SRS unit software , and retest.

DTC (SRS)
- Problem verification
-1. Clear the DTCs with the HDS.
- 2. Turn the vehicle to the ON mode, then wait for 10 seconds.
- 3. Check for DTCs with the HDS.
DTC Description DTC B0095-87 No signal from the right front impact sensor Is DTC B0095-87 indicated?
YES
The failure is duplicated. Go to step 2.
NO
Intermittent failure, the system is OK at this time. Go to Troubleshooting Intermittent Failures . If another DTC is indicated, troubleshoot the DTC.
- Connector connection check
-1. Turn the vehicle to the OFF (LOCK) mode.
- 2. Check the following connector connections.
SRS unit connector A (39P) Right front impact sensor 2P connector (on the engine compartment wire harness) Connector between the SRS unit and the right front impact sensor Are the connectors OK?
YES
Go to step 4.
NO
Go to step 3.
- System check
-1. Repair the poor connector connections whichever was the cause of the problem in step 2.
- 2. Clear the DTCs with the HDS.
- 3. Turn the vehicle to the ON mode, then wait for 10 seconds.
- 4. Check for DTCs with the HDS.
DTC Description DTC B0095-87 No signal from the right front impact sensor Is DTC B0095-87 indicated?
YES
Turn the vehicle to the OFF (LOCK) mode, then go to step 4.
NO
The system is OK at this time.
- Shorted wire check (RFS+ line to RFS- line)
-1. Disconnect the negative cable from the 12 volt battery, then wait at least 3 minutes.
- 2. Disconnect the following connectors:
SRS unit connector A (39P) Right front impact sensor 2P connector (on the engine compartment wire harness) - 3. Measure the resistance between test points 1 and 2.
Test condition Vehicle OFF (LOCK) mode SRS unit connector A (39P): disconnected Right front impact sensor 2P connector (on the engine compartment wire harness): disconnected Test circuit RFS+, RFS- Test point 1 SRS unit connector A (39P) No. 26 Test point 2 SRS unit connector A (39P) No. 27 Is there an open circuit, or at least 1 MΩ?
YES
The RFS+ and RFS- wires are not shorted. Go to step 5.
NO
Short to another wire in the engine compartment wire harness or the dashboard wire harness; replace the faulty harness, then clear the DTC.
- Shorted wire check (RFS+, RFS- lines)
-1. Measure the resistance between test points 1 and 2.
Test condition Vehicle OFF (LOCK) mode SRS unit connector A (39P): disconnected Right front impact sensor 2P connector (on the engine compartment wire harness): disconnected Test circuit RFS+ Test point 1 SRS unit connector A (39P) No. 26 Test point 2 Body ground Test circuit RFS- Test point 1 SRS unit connector A (39P) No. 27 Test point 2 Body ground Is there an open circuit, or at least 1 MΩ?
YES
The RFS+ and RFS- wires are not shorted. Go to step 6.
NO
Short to ground in the engine compartment wire harness or the dashboard wire harness; replace the faulty harness, then clear the DTC.
- Shorted wire check (RFS+, RFS- lines to power)
-1. Reconnect the negative cable to the 12 volt battery.
- 2. Turn the vehicle to the ON mode.
- 3. Measure the voltage between test points 1 and 2.
Test condition Vehicle ON mode SRS unit connector A (39P): disconnected Right front impact sensor 2P connector (on the engine compartment wire harness): disconnected Test circuit RFS+ Test point 1 SRS unit connector A (39P) No. 26 Test point 2 Body ground Test circuit RFS- Test point 1 SRS unit connector A (39P) No. 27 Test point 2 Body ground Is there 0.2 V or less?
YES
The RFS+ and RFS- wires are not shorted to power. Go to step 7.
NO
Short to power in the engine compartment wire harness or the dashboard wire harness; replace the faulty harness, then clear the DTC.
- Open wire check (RFS+, RFS- lines)
-1. Turn the vehicle to the OFF (LOCK) mode.
- 2. Connect the black terminal (A) of SRS simulator lead L to the SRS inflator simulator (jumper connector), then connect SRS simulator lead L to the right front impact sensor 2P connector (B) on the engine compartment wire harness.
- 3. Measure the resistance between test points 1 and 2.
Test condition Vehicle OFF (LOCK) mode SRS unit connector A (39P): disconnected Right front impact sensor 2P connector (on the engine compartment wire harness): disconnected Right front impact sensor 2P connector (on the engine compartment wire harness): connected to SRS simulator lead L Test circuit RFS+, RFS- Test point 1 SRS unit connector A (39P) No. 26 Test point 2 SRS unit connector A (39P) No. 27 Is there 1.0 Ω or less?
YES
The RFS+ and RFS- wires are OK. Replace the right front impact sensor , then clear the DTC, and retest. If the DTC is still present, replace the SRS unit .
NO
Open in the engine compartment wire harness or the dashboard wire harness; replace the faulty harness, then clear the DTC.
