Test condition OFF mode Front passenger's weight sensor unit connector C (6P): disconnected Front passenger's weight sensor (front inner side) 3P connector (on the front passenger's seat wire harness): disconnected Test circuit SWSS1, SWSG1 Test point 1 Front passenger's weight sensor (front inner side) 3P connector No. 2 (BRN) (on the front passenger's seat wire harness) Test point 2 Front passenger's weight sensor (front inner side) 3P connector No. 3 (BLK) (on the front passenger's seat wire harness) Is there an open circuit, or at least 1 MΩ?
YES
The SWSS1 and SWSG1 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.
- Open wire check (SWSS1 lines)
-1. Measure the resistance between test points 1 and 2.
Test condition OFF mode Front passenger's weight sensor unit connector C (6P): disconnected Front passenger's weight sensor (front inner side) 3P connector (on the front passenger's seat wire harness): disconnected Test circuit SWSS1 Test point 1 Front passenger's weight sensor unit connector C (6P) No. 2 (BRN) Test point 2 Front passenger's weight sensor (front inner side) 3P connector No. 2 (BRN) (on the front passenger's seat wire harness) 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.
