   B00C1-87 No Signal From the Front Passenger's Weight Sensor (front outer side)

   Is DTC B00C1-87 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.

2. Open wire check (SWS+ 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.

   SRS unit connector B (39P)

   Front passenger's weight sensor (front outer side) 3P connector (on the front passenger's seat wire harness)

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

   Test condition	Vehicle OFF (LOCK) mode
   	SRS unit connector B (39P)
   	Front passenger's weight sensor (front outer side) 3P connector (on the front passenger's seat wire harness): disconnected
   Test point 1	SRS unit connector B (39P) No. 26 - Refer to: SRS Unit Connector for Inputs and Outputs
   Test point 2	Front passenger's weight sensor (front outer side) 3P connector (female terminals) No. 1 (on the front passenger's seat wire harness):

   Is there 1.0 Ω or less?

   YES 

   The SWS- wire is OK. Go to step 4.

   NO 

   Open in the right side wire harness or the front passenger's seat wire harness; replace the faulty harness, then clear the DTC.

4. Open wire check (SWSS line)

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

   Test condition	Vehicle OFF (LOCK) mode
   	SRS unit connector B (39P): disconnected
   	Front passenger's weight sensor (front outer side) 3P connector (on the front passenger's seat wire harness): disconnected
   Test point 1	SRS unit connector B (39P) No. 30 - Refer to: SRS Unit Connector for Inputs and Outputs
   Test point 2	Front passenger's weight sensor (front outer side) 3P connector (female terminals) No. 2 (on the front passenger's seat wire harness):

   Is there 1.0 Ω or less?

   YES 

   Go to step 5.

   NO 

   Open in the right side wire harness or the front passenger's seat wire harness; replace the faulty harness, then clear the DTC.

5. Front passenger's weight sensor check

   -1. Substitute a known-good front passenger's weight sensor.

   - 2. Reconnect the following connectors.

   SRS unit connector B (39P)

   Front passenger's weight sensor (front inner side) 3P connector (on the front passenger's seat wire harness)

   Front passenger's weight sensor (front outer side) 3P connector (on the front passenger's seat wire harness)

   Front passenger's weight sensor (rear inner side) 3P connector (on the front passenger's seat wire harness)

   Front passenger's weight sensor (rear outer side) 3P connector (on the front passenger's seat wire harness)

   - 3. Reconnect the negative cable to the 12 volt battery.

   - 4. Clear the DTCs with the HDS.

   - 5. Turn the vehicle to the ON mode, then wait for 10 seconds.

   - 6. Check for DTCs with the HDS.
