NOTE:

	Before doing this troubleshooting procedure, find out if the vehicle was in a collision. If so, verify that all the required components were replaced with new components of the correct part number, and that they were properly installed.
	Before doing this troubleshooting procedure, review SRS Precautions and Procedures, General Troubleshooting Information, and 12 Volt Battery Terminal Disconnection and Reconnection.
	Before replacing the SRS unit, check the SRS unit software version with the HDS. If the software version is not the latest, update the SRS unit software, and retest.

Shorted wire check (RS3? line to RS3? line):

Shorted wire check (RS3? line to RS3? 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.

Right side impact sensor (second) 4P connector (on the right side wire harness)

Right side impact sensor (third) 2P connector (on the right side wire harness)

?4.

Measure the resistance between test points 1 and 2.

Test condition	Vehicle OFF (LOCK) mode
	Right side impact sensor (second) 4P connector (on the right side wire harness): disconnected
	Right side impact sensor (third) 2P connector (on the right side wire harness): disconnected
Test point 1	Right side impact sensor (third) 2P connector No. 1 (on the right side wire harness)
Test point 2	Right side impact sensor (third) 2P connector No. 2 (on the right side wire harness)

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


	YES

The RS3? and RS3? wires are not shorted. Go to step 3.


	NO

Short to another wire in the right side wire harness between the right side impact sensor (second) and the right side impact sensor (third); replace the right side wire harness, then clear the DTC.?

Shorted wire check (RS3?, RS3? lines):

Shorted wire check (RS3?, RS3? lines)

?1.

Measure the resistance between test points 1 and 2.

Test condition	Vehicle OFF (LOCK) mode
	Right side impact sensor (second) 4P connector (on the right side wire harness): disconnected
	Right side impact sensor (third) 2P connector (on the right side wire harness): disconnected
Test point 1	Right side impact sensor (third) 2P connector No. 2 (on the right side wire harness)
Test point 2	Body ground

Test point 1	Right side impact sensor (third) 2P connector No. 1 (on the right side wire harness)
Test point 2	Body ground

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


	YES

The RS3? and RS3? wires are not shorted. Go to step 4.


	NO

Short to ground in the right side wire harness between the right side impact sensor (second) and the right side impact sensor (third); replace the right side wire harness, then clear the DTC.?

Shorted wire check (RS3?, RS3? lines to power):

Shorted wire check (RS3?, RS3? lines to power)

?1.	Reconnect the negative cable to the 12 volt battery.

?2.	Turn the vehicle to the ON mode.

?3.

Measure the voltage between test points 1 and 2.

Test condition	Vehicle ON mode
	Right side impact sensor (second) 4P connector (on the right side wire harness): disconnected
	Right side impact sensor (third) 2P connector (on the right side wire harness): disconnected
Test point 1	Right side impact sensor (third) 2P connector No. 2 (on the right side wire harness)
Test point 2	Body ground

Test point 1	Right side impact sensor (third) 2P connector No. 1 (on the right side wire harness)
Test point 2	Body ground

Is there 0.2 V or less?


	YES

The RS3? and RS3? wires are not shorted to power. Go to step 5.


	NO

Short to power in the right side wire harness between the right side impact sensor (second) and the right side impact sensor (third); replace the right side wire harness, then clear the DTC.?

Open wire check (RS3?, RS3? lines):

Open wire check (RS3?, RS3? 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 side impact sensor (third) 2P connector (B) on the right side wire harness.

?3.

Measure the resistance between test points 1 and 2.
