DTC 62 - Redundant Sir Indicator Circuit Failure
WARNING: This page is about a different car, the 1995 Suzuki Swift and 1995 Geo Metro. However, it is still accessible from the selected car via links, so may be relevant.
When Ignition switch is turned to ON position, system voltage is supplied to AIR BAG warning lamp and to terminal B9 of SDM. SDM confirms proper SIR system operation by flashing AIR BAG warning lamp 7 times, alternately energizing primary and redundant lamp drivers. If redundant lamp driver output is not between pre-determined limits, and voltage at B9 terminal of SDM is greater than normal, SDM will set DTC 62. If this fault occurs intermittently, most probable causes are a poor connection at SDM, a damaged SIR wiring harness, or a poor ground to case of SDM.
NOTE:
Test numbers below refer to test numbers in chart.
- Verifies integrity of SIR wiring harness.
WARNING:
To avoid air bag deployment and injury when trouble shooting system, only use test equipment specified in diagnostic charts. Under no circumstances should battery powered test equipment or test light be used. Carefully follow all instructions.
