NOTE:
1. Problem verification:
Is DTC 82-13 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.
1. Open wire check (SWSP1 line):
Is there about 5 V?
YES
The SWSP1 wire is OK. Go to step 3.
NO
Open in the front passenger's seat wire harness; replace the front passenger's seat wire harness, then clear the DTC.
3. Shorted wire check (SWS1 line):
Front passenger's weight sensor unit connector C (6P)
Is there an open circuit, or at least 1 MΩ?
YES
The SWS1 wire is not shorted. Go to step 4.
NO
Short to ground in the front passenger's seat wire harness; replace the front passenger's seat wire harness, then clear the DTC.
4. Shorted wire check (SWS1 line to SWS1G line):
Measure the resistance between test points 1 and 2.
Is there an open circuit, or at least 1 MΩ?
YES
The SWS1 and SWS1G wires are not shorted. Go to step 5.
NO
Short to another wire in the front passenger's seat wire harness; replace the front passenger's seat wire harness, then clear the DTC.
5. Open wire check (SWS1 lines):
Measure the resistance between test points 1 and 2.
Is there 1.0 Ω or less?
YES
Faulty front passenger's weight sensor (front inner side); replace the front passenger's seat rail including all four front passenger's weight sensors, then clear the DTC.
NO
Open in the front passenger's seat wire harness; replace the front passenger's seat wire harness, then clear the DTC.
DTC TROUBLESHOOTING 82-23: NO SIGNAL FROM THE FRONT PASSENGER'S WEIGHT SENSOR (REAR INNER SIDE)
NOTE:
1. Problem verification:
Is DTC 82-23 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 (SWSP2 line):
Is there about 5 V?
YES
The SWSP2 wire is OK. Go to step 3.
NO
Open in the front passenger's seat wire harness; replace the front passenger's seat wire harness, then clear the DTC.
3. Shorted wire check (SWS2 line):
Front passenger's weight sensor unit connector C (6P)
Is there an open circuit, or at least 1 MΩ?
YES
The SWS2 wire is not shorted. Go to step 4.
NO
Short to ground in the front passenger's seat wire harness; replace the front passenger's seat wire harness, then clear the DTC.
4. Shorted wire check (SWS2 line to SWS2G line):
Measure the resistance between test points 1 and 2.
Is there an open circuit, or at least 1 MΩ?
YES
The SWS2 and SWS2G wires are not shorted. Go to step 5.
NO
Short to another wire in the front passenger's seat wire harness; replace the front passenger's seat wire harness, then clear the DTC.
5. Open wire check (SWS2 lines):
Measure the resistance between test points 1 and 2.
Is there 1.0 Ω or less?
YES
Faulty front passenger's weight sensor (rear inner side); replace the front passenger's seat rail including all four front passenger's weight sensors, then clear the DTC.
NO
Open in the front passenger's seat wire harness; replace the front passenger's seat wire harness, then clear the DTC.
