DTC 45-11
DTC 45-11: No Signal from the Left Side Impact Sensor (second)Special Tools Required
- SRS inflator simulator 07SAZ-TB4011A
- SRS simulator lead H 07YAZ-S3AA100
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 45-11 indicated?
YES - Go to step 3.
NO - Intermittent failure, system is OK at this time. Go to Troubleshooting Intermittent Failures. Initial Inspection and Diagnostic Overview 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 connections between the SRS unit connector C (28P) and the SRS unit, between the left side wire harness 2P connector and the left side impact sensor (second), at left side wire harness 16P connector C655 and right side wire harness connector C655.
Are the connections OK?
YES - Go to step 5.
NO - Repair the poor connections and retest. If the DTC 45-11 is still present, go to step 5.
5. Disconnect the left side wire harness 2P connector (A) from the left side impact sensor (second).
6. Disconnect SRS unit connector C (28P) from the SRS unit.
7. Check resistance between the No. 17 and No. 18 terminals of SRS unit connector C (28P). There should be an open circuit or at least 1 MOhms.
Is the resistance as specified?
YES - Go to step 8.
NO - Short in the left side wire harness or right side wire harness; replace the faulty harness.
8. Check resistance between the No. 17 terminal of SRS unit connector C (28P) and body ground, and between the No. 18 terminal and body ground. There should be an open circuit or at least 1 MOhms.
Is the resistance as specified?
YES - Go to step 9.
NO - Short to ground in the left side wire harness or right side wire harness; replace the faulty harness.
9. Reconnect the negative cable to the battery.
10. Turn the ignition switch ON (II).
11. Check for voltage between the No. 17 terminal of SRS unit connector C (28P) and body ground, and between the No. 18 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 left side wire harness or right side wire harness; replace the faulty harness.
12. Turn the ignition switch OFF.
13. Connect the SRS inflator simulator (jumper connector) and simulator lead H to the left side wire harness 2P connector (A).
14. Check resistance between the No. 17 and No. 18 terminals of SRS unit connector C (28P). 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 left side wire harness or right side wire harness; replace the faulty harness.
