| DTC 42-1x (42-10 to 42-19, 42-1A to 42-1F): | No Signal from the Right Front Impact Sensor |
Special Tools Required
SRS inflator simulator ( 07SAZ-TB4011A)
| 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 42-1x indicated? YES - Go to 3. NO - Intermittent failure, system is OK at this time. Go to Troubleshooting Intermittent Failures. If another DTC is indicated, go to the DTC troubleshooting index for troubleshooting details. |
| 3. | Turn the ignition switch OFF. Check the connections between the SRS unit connector A (28P) and the SRS unit, and between the front engine compartment wire harness 2P connector and the right front impact sensor, and at engine compartment wire harness 4P connector. Are the connections OK? YES - Go to 4. NO - Repair the poor connections and retest. If DTC 42-1x still present, go to 4. |
| 4. | Turn the ignition switch OFF. Disconnect the battery negative cable, and wait for 3 minutes. |
| 5. | Disconnect the driver's airbag 2P connector (A). |
| 6. | Disconnect the front passenger's airbag 2P connector (A). |
| 7. | Disconnect both seat belt tensioner 4P connectors (A). |
| 8. | Disconnect the engine compartment wire harness 2P connector (A) from the right front impact sensor. |
| 9. | Disconnect the SRS unit connector A (28P) from the SRS unit. |
| 10. | Check resistance between the No. 16 terminal and the No. 28 terminal of SRS unit connector A (28P). There should be an open circuit, or at least 1 MW. Is the resistance as specified? YES - Go to 11. NO - Short in the engine compartment wire harness or dashboard wire harness; replace the faulty harness.n |
| 11. | Reconnect the battery negative cable. |
| 12. | Turn the ignition switch ON (II). |
| 13. | Check for voltage between the No. 28 terminal of SRS unit connector A (28P) and body ground. There should be 1 V or less. Is the voltage as specified? YES - Go to 14. NO - Short to power in the engine compartment wire harness or dashboard wire harness; replace the faulty harness.n |
| 14. | Turn the ignition switch OFF. |
| 15. | Connect the SRS inflator simulator (jumper connector) and the simulator lead to the engine compartment wire harness 2P connector (A). |
| 16. | Check resistance between the No. 16 and No. 28 terminals of SRS unit connector A (28P). There should be 1W or less. Is the resistance as specified? YES - Faulty right front impact sensor or SRS unit. Replace the right front impact sensor; if the problem is still present, replace the SRS unit.n NO - Faulty engine compartment wire harness or dashboard wire harness; replace the faulty harness.n |
