Special Tools Required

SRS Inflator Simulator 07SAZ-TB4011A

SRS Simulator Lead L 070AZ-SNAA300

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.

DTC Description	DTC
B0097-87 No signal from the right side impact sensor (second)

DTC (SRS)

1. Problem verification:

- 1. Clear the DTCs with the HDS .

- 2. Turn the vehicle to the ON mode, then wait for 10 seconds.

- 3. Check for DTCs with the HDS .

B0097-87 No signal from the right side impact sensor (second)

Is DTC B0097-87 indicated?

YES

The failure is duplicated. Go to step 2.

Intermittent failure, the system is OK at this time. Go to Troubleshooting Intermittent Failures . If another DTC is indicated, troubleshoot the DTC.

2. Shorted wire check (RS2+ line to RS2- 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 (first) 4P connector (on the floor wire harness)

Right side impact sensor (second) 2P connector (on the floor wire harness)

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

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

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

YES

The RS2+ and RS2- wires are not shorted. Go to step 3.

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

3. Shorted wire check (RS2+, RS2- lines):

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

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

Test point 2

Body ground

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

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

YES

The RS2+ and RS2- wires are not shorted. Go to step 4.

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

4. Shorted wire check (RS2+, RS2- 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 (first) 4P connector (on the floor wire harness): disconnected
	Right side impact sensor (second) 2P connector (on the floor wire harness): disconnected
Test point 1	Right side impact sensor (second) 2P connector No. 1 (on the floor wire harness)
Test point 2	Body ground

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

Is there 0.2 V or less?

YES

The RS2+ and RS2- wires are not shorted to power. Go to step 5.

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

5. Open wire check (RS2+, RS2- lines):

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

- 2. Connect the red 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 (first) 4P connector (B) on the floor wire harness.

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

Test condition	Vehicle OFF (LOCK) mode
	Right side impact sensor (first) 4P connector (on the floor wire harness): disconnected
	Right side impact sensor (second) 2P connector (on the floor wire harness): disconnected
	Right side impact sensor (first) 4P connector (on the floor wire harness): connected to SRS simulator lead L
Test point 1	Right side impact sensor (second) 2P connector No. 1 (on the floor wire harness)
Test point 2	Right side impact sensor (second) 2P connector No. 2 (on the floor wire harness)

Is there 1.0 Ω or less?

YES

The RS2+ and RS2- wires are OK. Replace the right side impact sensor (second) - Refer to: Side Impact Sensor (First) Removal and Installation Side Impact Sensor (Second) Removal and Installation , then clear the DTC, and retest. If the DTC is still present, replace the SRS unit .

Open in the floor wire harness between the right side impact sensor (first) and the right side impact sensor (second); replace the floor wire harness, then clear the DTC.
