Is there about 5 V?

YES

The SWSP3 wire is OK. Go to step 3.

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

Shorted wire check (SWSS3 line)

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

- 2. Disconnect the following connector.

Front passenger's weight sensor unit connector B (6P)

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

Test condition	Vehicle OFF (LOCK) mode
Test condition	Front passenger's weight sensor unit connector B (6P): disconnected
	Front passenger's weight sensor (front outer side) 3P connector (on the front passenger's seat wire harness): disconnected

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

YES

The SWSS3 wire is not shorted. Go to step 4.

Short to ground in the front passenger's seat wire harness; replace the front passenger's seat wire harness, then clear the DTC.

Shorted wire check (SWSS3 line to SWSG3 line)

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

Test condition	Vehicle OFF (LOCK) mode
Test condition	Front passenger's weight sensor unit connector B (6P): disconnected
	Front passenger's weight sensor (front outer side) 3P connector (on the front passenger's seat wire harness): disconnected
Test circuit	SWSS3, SWSG3
Test point 1	Front passenger's weight sensor (front outer side) 3P connector No. 2 (BLU) (on the front passenger's seat wire harness)
Test point 2	Front passenger's weight sensor (front outer side) 3P connector No. 3 (LT GRN) (on the front passenger's seat wire harness)

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

YES

The SWSS3 and SWSG3 wires are not shorted. Go to step 5.

YES

Short to another wire in the front passenger's seat wire harness; replace the front passenger's seat wire harness, then clear the DTC.
