DTC 45-1x
DTC 45-1x ("x" can be 0 thru 9 or A thru F):No Signal From the Left Side Impact Sensor (second)Special Tools Required
- SRS inflator simulator 07SAZ-TB4011A
- SRS simulator lead H 07YAZ-S3AA100
NOTE: Before doing this troubleshooting procedure, review SRS Precautions and Procedures.
1. Erase the DTC memory.
2. Turn the ignition switch ON (II), and check that the SRS indicator comes on for about 6 seconds and then goes off.
Does the SRS indicator stay on, and is DTC 45-1x indicated?
YES - Go to step 3.
NO - Intermittent failure, system is OK at this time. Go to Troubleshooting Intermittent Failures Troubleshooting Intermittent Failures. If another DTC is indicated, go to the DTC Troubleshooting Index Diagnostic Trouble Code Descriptions.
3. Turn the ignition switch OFF. Disconnect the negative cable from the battery, and wait for 3 minutes.
4. Check the connection between the side curtain airbag harness 2P connector and the left side impact sensor (second).
Is the connection OK?
YES - Go to step 5.
NO - Repair the poor connection and retest. If DTC 45-1x is still present, go to step 5.
5. Disconnect the side curtain airbag harness 2P connector (A) from the left side impact sensor (second).
6. Disconnect SRS unit connector C (16P) from the SRS unit.
7. Check resistance between the No. 9 and No. 10 terminals of SRS unit connector C (16P). There should be an open circuit or at least 1 Mohm.
Is the resistance as specified?
YES - Go to step 8.
NO - Short in the side curtain airbag harness; replace the side curtain airbag harness.
8. Check resistance between the No. 9 terminal of SRS unit connector C (16P) and body ground, and between the No. 10 terminal and body ground. There should be an open circuit or at least 1 Mohm.
Is the resistance as specified?
YES - Go to step 9.
NO - Short to ground in the sides curtain airbag harness; replace the side curtain airbag harness.
9. Reconnect the negative cable to the battery.
10. Turn the ignition switch ON (II).
11. Check for voltage between the No. 9 terminal of SRS unit connector C (16P) and body ground, and between the No. 10 terminal and body ground. There should be 1 V or less.
Is the voltage as specified?
YES - Go to step 12.
NO - Short to power in the side curtain airbag harness; replace the side curtain airbag harness.
12. Turn the ignition switch OFF.
13. Connect the SRS inflator simulator (jumper connector) and the simulator lead to the side curtain airbag harness 2P connector (A).
14. Check resistance between the No. 9 and No. 10 terminals of SRS unit connector C (16P). There should be 1.0 Ohm or less.
Is the resistance as specified?
YES - Faulty left side impact sensor (second) or SRS unit; replace the left side impact sensor (second). If the problem is still present, replace the SRS unit.
NO - Open in the side curtain airbag harness; replace the side curtain airbag harness.
