• Before doing this troubleshooting procedure, review SRS Precautions and Procedures , General Troubleshooting Information , and 12 Volt Battery Terminal Disconnection and Reconnection .

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
   B00C2-87 No signal from the front passenger's weight sensor (rear inner side)

   Is DTC B00C2-87 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+/PWR 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 (rear inner 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): disconnected
   	Front passenger's weight sensor (rear inner side) 3P connector (on the front passenger's seat wire harness): disconnected
   Test point 1	SRS unit connector B (39P) No. 26
   Test point 2	Front passenger's weight sensor (rear inner 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-/GND SWS wire is OK. Go to step 4.

   NO 

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

4. Open wire check (SWSS/LIN SWS 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 (rear inner side) 3P connector (on the front passenger's seat wire harness): disconnected
   Test point 1	SRS unit connector B (39P) No. 30
   Test point 2	Front passenger's weight sensor (rear inner side) 3P connector (female terminals) No. 2 (on the front passenger's seat wire harness):

   Is there 1.0 Ω or less?

   YES 

   The SWSS/LIN SWS wire is OK. Go to step 5.

   NO 

   Open in the floor 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 sensors as an assembly .

   -2. Reconnect the following connectors.

   SRS unit connector B (39P)

   Front passenger's weight sensor (rear inner 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.
