DTC 46-1x
DTC 46-1x ("x" can be 0 thru 9 or A thru F): No Signal from the Right 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 and General Troubleshooting Information.
1. Clear 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 46-1x 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, troubleshoot the DTC.
3. Turn the ignition switch OFF. Disconnect the negative cable from the battery, and wait for 3 minutes.
4. Check the connection between the right side wire harness 2P connector and the right side impact sensor (second).
Is the connection OK?
YES - Go to step 5.
NO - Repair the poor connection and retest. If the DTC 46-1x is still present, go to step 5.
5. Disconnect the right side wire harness 2P connector (A) from the right side impact sensor (second).
6. Disconnect SRS unit connector C (28P) from the SRS unit.
7. Measure the resistance between the No.19 and No.20 terminals of SRS unit connector C. Then measure the resistance between the No.19 terminal and body ground and the No.20 terminal and body ground. There should be an open circuit or at least 1 Mohms.
Is the resistance as specified?
YES - Go to step 8.
NO - Short in or to ground the SRS subharness, SRS harness, left side wire harness and/or right side wire harness; replace the faulty harness.
8. Reconnect the negative cable to the battery.
9. Turn the ignition switch ON (II).
10. Measure the voltage between the No.19 terminal of SRS unit connector C (28P) and body ground, and between the No.20 terminal and body ground. There should be less than 1 V.
Is the voltage as specified?
YES - Go to step 11.
NO - Short to power in the SRS subharness, SRS harness, left side wire harness and/or right side wire harness; replace the faulty harness.
11. Turn the ignition switch OFF.
12. Connect the SRS inflator simulator (jumper connector) and simulator lead H to the right side wire harness 2P connector (A).
13. Measure the resistance between the No.19 and No.20 terminals of SRS unit connector C (28P). There should be less than 1.0 ohm.
Is the resistance as specified?
YES - Faulty right side impact sensor (second) or SRS unit; replace the right side impact sensor (second). If the problem is still present, replace the SRS unit.
NO - Open in the SRS subharness, SRS harness, left side wire harness and/or right side wire harness; replace the faulty harness.
