Is DTC B0095-87 indicated?

YES

Turn the vehicle to the OFF (LOCK) mode, then go to step 4.

The system is OK at this time.

Shorted wire check (RFS+ line to RFS- line)

-1. Disconnect the negative cable from the Battery, then wait at least 3 minutes.

- 2. Disconnect the following connectors.

SRS unit connector A (39P)

Right front impact sensor 2P connector (on the engine compartment wire harness)

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

Test condition	Vehicle OFF (LOCK) mode
	SRS unit connector A (39P): disconnected
	Right front impact sensor 2P connector (on the engine compartment wire harness): disconnected
Test point 1	SRS unit connector A (39P) No. 29 - Refer to: SRS Unit Connector for Inputs and Outputs (2017 2018 2019 2020)
Test point 2	SRS unit connector A (39P) No. 30 - Refer to: SRS Unit Connector for Inputs and Outputs (2017 2018 2019 2020)

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

YES

The RFS+ and RFS- wires are not shorted. Go to step 5.

Short to another wire in the engine compartment wire harness or the dashboard wire harness; replace the faulty harness, then clear the DTC.

Shorted wire check (RFS+, RFS- lines)

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

Test condition	Vehicle OFF (LOCK) mode
	SRS unit connector A (39P): disconnected
	Right front impact sensor 2P connector (on the engine compartment wire harness): disconnected
Test point 1	SRS unit connector A (39P) No. 29 - Refer to: SRS Unit Connector for Inputs and Outputs (2017 2018 2019 2020)
Test point 2	Body ground

Test point 1	SRS unit connector A (39P) No. 30 - Refer to: SRS Unit Connector for Inputs and Outputs (2017 2018 2019 2020),
Test point 2	Body ground

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

YES

The RFS+ and RFS- wires are not shorted. Go to step 6.

Short to ground in the engine compartment wire harness or the dashboard wire harness; replace the faulty harness, then clear the DTC.

Shorted wire check (RFS+, RFS- lines to power)

-1. the negative cable to the Battery.

- 2. Turn the vehicle to the ON mode.

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

Test condition	Vehicle ON mode
	SRS unit connector A (39P): disconnected
	Right front impact sensor 2P connector (on the engine compartment wire harness): disconnected
Test point 1	SRS unit connector A (39P) No. 29 - Refer to: SRS Unit Connector for Inputs and Outputs (2017 2018 2019 2020)
Test point 2	Body ground

Test point 1	SRS unit connector A (39P) No. 30 - Refer to: SRS Unit Connector for Inputs and Outputs (2017 2018 2019 2020),
Test point 2	Body ground

Is there 0.2 V or less?

YES

The RFS+ and RFS- wires are not shorted to power. Go to step 7.

Short to power in the engine compartment wire harness or the dashboard wire harness; replace the faulty harness, then clear the DTC.

Open wire check (RFS+, RFS- lines)

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

- 2. Connect the black terminal (A) of SRS simulator lead L to the SRS inflator simulator (jumper connector), then connect SRS simulator lead L to the right front impact sensor 2P connector (B) on the right engine compartment wire harness.
