Is DTC B00DF-13 indicated?

YES

The failure is duplicated. Go to step 2.

NO

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

2. Front passenger's airbag ON/OFF switch check:

1. Turn the vehicle to the OFF (LOCK) mode.
2. Disconnect the following connector.

Front passenger's airbag ON/OFF switch 4P connector (on the dashboard wire harness)

3. Measure the resistance between the front passenger's airbag ON/OFF switch 4P connector terminals No. 1 and No. 4 according to the table.

Is the resistance as specified?

YES

Go to step 3.

NO

Faulty front passenger's airbag ON/OFF switch or poor connection at front passenger's airbag ON/OFF switch 4P connector and the front passenger's airbag ON/OFF switch. Check the connection; if the connection is OK, replace the front passenger's airbag ON/OFF switch - Refer to: Front Passenger's Airbag ON/OFF Switch Removal and Installation, or Front Passenger's Airbag ON/OFF Indicator Removal and Installation, then clear the DTC.

3. Shorted wire check (ACS, GND lines to power):

1. Turn the vehicle to the ON mode.
2. Measure the voltage between test points 1 and 2.

Is there 0.2 V or less?

YES

The ACS and GND wires are not shorted to power. Go to step 4.

NO

Short to power in the dashboard wire harness; replace the dashboard wire harness, then clear the DTC.

4. Open wire check (ACS line):

2. Disconnect the negative cable from the 12 volt battery, then wait at least 3 minutes.
3. Disconnect the following connector.

SRS unit connector A (39P)

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

Is there 1.0 Ω or less?

YES

The ACS wire is OK. Go to step 5.

NO

Open in the dashboard wire harness; replace the dashboard wire harness, then clear the DTC.

5. Open wire check (GND line):

Measure the resistance between test points 1 and 2.

Is there 1.0 Ω or less?

YES

The GND wire is OK. Replace the SRS unit.

NO

Open in the dashboard wire harness; check for a poor ground at G403. If the ground is OK, replace the dashboard wire harness, then clear the DTC.

DTC TROUBLESHOOTING B2800-49, B2801-49, U3000-49: INTERNAL FAILURE OF THE SRS UNIT

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 troubleshooting any of these DTCs, check the 12 volt battery/system voltage and 12 volt battery cable connections. If the voltage is low, repair the charging system, test and charge the 12 volt battery, or replace the 12 volt battery before troubleshooting the SRS. If the 12 volt battery/system voltage is OK, ask the customer if the 12 volt battery ever went dead or if the engine was started and run with the 12 volt battery in a low state of charge. A dead 12 volt battery may trigger one or more of these DTCs.
• Before doing this troubleshooting procedure, review SRS Precautions and Procedures and General Troubleshooting Information.
• 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.

1. Problem verification:
