DTC B0097-87: No Signal From the Right Side Impact Sensor (second) (2015-17)

Special Tools Required: 

SRS Inflator Simulator 07SAZ-TB4011A 

SRS Simulator Lead L 070AZ-SNAA300 

NOTE: 

Before doing this troubleshooting procedure: 

DTC Description DTC
B0097-87 No signal from the right side impact sensor (second)  

DTC (SRS)

  1. 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
    B0097-87 No signal from the right side impact sensor (second)  

    Is DTC B0097-87 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 - Refer to: How to Troubleshoot the SRS . If another DTC is indicated, troubleshoot the DTC.

  2. Shorted wire check (RS2+ line to RS2- line)

    -1. Turn the vehicle to the OFF (LOCK) mode.

    - 2. Disconnect the negative cable from the 12 volt battery, then wait at least 3 minutes.

    - 3. Disconnect the following connectors.

    Right side impact sensor (first) 4P connector (on the right side wire harness)
    Right side impact sensor (second) 2P connector (on the right side wire harness)

    - 4. Measure the resistance between test points 1 and 2.

    Test condition Vehicle OFF (LOCK) mode
    Right side impact sensor (first) 4P connector (on the right side wire harness): disconnected
    Right side impact sensor (second) 2P connector (on the right side wire harness): disconnected
    Test point 1 Right side impact sensor (second) 2P connector No. 1 (on the right side wire harness)
    Test point 2 Right side impact sensor (second) 2P connector No. 2 (on the right side wire harness)

    Is there an open circuit, or at least 1 MΩ?

    YES 

    The RS2+ and RS2- wires are not shorted. Go to step 3.

    NO 

    Short to another wire in the right side wire harness between the right side impact sensor (first) and the right side impact sensor (second); replace the right side wire harness, then clear the DTC.

  3. Shorted wire check (RS2+, RS2- lines)

    -1. Measure the resistance between test points 1 and 2.

    Test condition Vehicle OFF (LOCK) mode
    Right side impact sensor (first) 4P connector (on the right side wire harness): disconnected
    Right side impact sensor (second) 2P connector (on the right side wire harness): disconnected
    Test point 1 Right side impact sensor (second) 2P connector No. 1 (on the right side wire harness)
    Test point 2 Body ground
    Test point 1 Right side impact sensor (second) 2P connector No. 2 (on the right side wire harness)
    Test point 2 Body ground

    Is there an open circuit, or at least 1 MΩ?

    YES 

    The RS2+ and RS2- wires are not shorted. Go to step 4.

    NO 

    Short to ground in the right side wire harness between the right side impact sensor (first) and the right side impact sensor (second); replace the right side wire harness, then clear the DTC.

  4. Shorted wire check (RS2+, RS2- 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
    Right side impact sensor (first) 4P connector (on the right side wire harness): disconnected
    Right side impact sensor (second) 2P connector (on the right side wire harness): disconnected
    Test point 1 Right side impact sensor (second) 2P connector No. 1 (on the right side wire harness)
    Test point 2 Body ground
    Test point 1 Right side impact sensor (second) 2P connector No. 2 (on the right side wire harness)
    Test point 2 Body ground

    Is there 0.2 V or less?

    YES 

    The RS2+ and RS2- wires are not shorted to power. Go to step 5.

    NO 

    Short to power in the right side wire harness between the right side impact sensor (first) and the right side impact sensor (second); replace the right side wire harness, then clear the DTC.

  5. Open wire check (RS2+, RS2- lines)

    -1. Turn the vehicle to the OFF (LOCK) mode.

    - 2. Connect the red terminal (A) of SRS simulator lead L to the SRS inflator simulator (jumper connector), then connect SRS simulator lead L to the right side impact sensor (first) 4P connector (B) on the right side wire harness.

    - 3. Measure the resistance between test points 1 and 2.

    Test condition Vehicle OFF (LOCK) mode
    Right side impact sensor (first) 4P connector (on the right side wire harness): disconnected
    Right side impact sensor (second) 2P connector (on the right side wire harness): disconnected
    Right side impact sensor (first) 4P connector (on the right side wire harness): connected to SRS simulator lead L
    Test point 1 Right side impact sensor (second) 2P connector No. 1 (on the right side wire harness)
    Test point 2 Right side impact sensor (second) 2P connector No. 2 (on the right side wire harness)

    Is there 1.0 Ω or less?

    YES 

    The RS2+ and RS2- wires are OK. Replace the right side impact sensor (second) (Refer to: Side Impact Sensor (Second) Removal and Installation ), then clear the DTC, and retest. If the DTC is still present, replace the SRS unit - Refer to: SRS Unit Removal and Installation .

    NO 

    Open in the right side wire harness between the right side impact sensor (first) and the right side impact sensor (second); replace the right side wire harness, then clear the DTC.
