WARNING: This page is about a different car, the 2003 Mazda Protege5 and 2003 Mazda Protege. However, it is still accessible from the selected car via links, so may be relevant.
- Before proceeding, see AIR BAG SAFETY PRECAUTIONS . Turn ignition switch to LOCK position. Disconnect negative battery cable. Remove driver-side air bag module. See DRIVER-SIDE AIR BAG MODULE under REMOVAL & INSTALLATION. Inspect clockspring short bar separator. If clockspring short bar separator is okay, and if DTC 6 was retrieved as a present malfunction, go to next step. If clockspring short bar separator is okay, and if DTC 6 was retrieved as a past malfunction, go to step 6. If clockspring short bar separator is not okay, replace clockspring and go to step 8. See CLOCKSPRING under REMOVAL & INSTALLATION.
- Connect leads of Fuel And Thermometer Checker (49 0839 285) to clockspring-to-air bag connector, terminals 3A and 3B at steering wheel. See Fig 1. Set resistance of checker to 2 ohms. Connect negative battery cable. Turn ignition to ON position. If DTC 6 is indicated, go to next step. If DTC 6 is not indicated, replace driver-side air bag module and go to step 8.
- Turn ignition off. Disconnect negative battery cable and wait more than one minute for back-up power to deplete. Remove steering column covers. Disconnect lower clockspring connector. If clockspring short bar separator is okay, go to next step. If clockspring short bar separator is not okay, replace clockspring-to-SAS control module air bag wiring harness and go to step 8.
- Connect leads of fuel and thermometer checker to lower clockspring 2-pin connector, terminals "A" and "B" at base of steering wheel. Set resistance of checker to 2 ohms. Connect negative battery cable. Turn ignition to ON position. If DTC 6 is indicated, go to next step. If DTC 6 is not indicated, replace clockspring and go to step 8. See CLOCKSPRING under REMOVAL & INSTALLATION.
- Disable air bag system. See DISABLING SYSTEM under DISABLING & ACTIVATING AIR BAG SYSTEM. Access and disconnect SAS control module connector. See SAS CONTROL MODULE under REMOVAL & INSTALLATION. Inspect air bag harness and connectors for damage or defect. If harness and connectors are okay, replace SAS control module and go to step 8. If harness and connectors are not okay, replace air bag wiring harness and go to step 8.
- Remove clockspring. See CLOCKSPRING under REMOVAL & INSTALLATION. Check clockspring continuity between specified terminals. See Fig 1. If continuity exists as specified, go to next step. If continuity does not exist as specified, replace clockspring and go to step 8.
- Disable air bag system. See DISABLING SYSTEM under DISABLING & ACTIVATING AIR BAG SYSTEM. Access and disconnect SAS control module connector. See SAS CONTROL MODULE under REMOVAL & INSTALLATION. Check wiring harness between SAS control module connector, terminal 2D and clockspring connector terminal "A" (Yellow/Red wire), and between SAS control module connector, terminal 2G and clockspring connector, terminal "B" (Yellow/Black wire) for short to ground, power supply or an open circuit. See Figure & Fig 1 . If wiring harness is okay, replace driver-side air bag module and go to step 8. See DRIVER-SIDE AIR BAG MODULE under REMOVAL & INSTALLATION. If wiring harness is not okay, replace wiring harness and go to step 8.
- Disconnect negative battery cable. Reconnect all connectors and install previously removed components. Reconnect negative battery cable. Clear past malfunction DTCs. See CLEARING PAST MALFUNCTION DTCS under DIAGNOSTICS. Perform system operation check. See SYSTEM OPERATION CHECK . If AIR BAG warning light operates normally, trouble shooting is complete. If AIR BAG warning light does not operate normally, reconfirm malfunction symptoms.
