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 . 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. Access and disconnect right side air bag sensor. See SIDE AIR BAG SENSOR under REMOVAL & INSTALLATION.
- Check wiring harness between SAS control module connector, terminal 1L and right side air bag module connector, terminal "A" (White wire), and between SAS control module connector, terminal 1J and right side air bag module connector, terminal "B" (White/Red wire), for short to ground, power supply or an open circuit. See Figure & Figure . If wiring harness is okay, go to next step. If wiring harness is not okay, replace air bag wiring harness and go to step 6.
- Check wiring harness between SAS control module connector, terminal 1H and right side air bag module connector, terminal "C" (Light Green wire), and SAS control module connector, terminal 1G and right side air bag module connector, terminal "D" (White/Blue wire) for short to ground, power supply or an open circuit. See Figure & Figure . If wiring harness is okay and DTC 35 was retrieved as a present malfunction, go to next step. If wiring harness is okay and DTC 35 was retrieved as a past malfunction, replace right air bag sensor and go to step 6. See SIDE AIR BAG SENSOR under REMOVAL & INSTALLATION. If wiring harness is not okay, replace air bag wiring harness and go to step 6.
- Measure resistance between right air bag sensor connector terminals, "C" and "D". See Figure. If resistance is about one k/ohms, replace SAS control module and go to next step. See SAS CONTROL MODULE under REMOVAL & INSTALLATION. If resistance is not about one k/ohms, replace right side air bag sensor and go to step 6.
- Reconnect connectors to SAS control module, right side air bag sensor, clockspring, passenger-side air bag module and, right and left side air bag modules. Reconnect negative battery cable and turn ignition on. If DTC 35 is indicated, replace right side air bag sensor and go to next step. If DTC 35 is not indicated, go to next step.
- 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.
