DTC 61 - Air Bag Warning Light Circuit Failure: Description

When the ignition switch is first turned ON battery voltage is applied to the AIR BAG warning light and the Ignition 1 input terminal A7. The SDM responds by flashing the AIR BAG warning light seven times alternating between the primary and redundant light drivers. The SDM monitors the primary light driver output by comparing the output state at SIR Indicator terminal A9 to the microprocessor commanded state. When Ignition 1 is above a specified and the output state doe not match the commanded state of the primary light driver for 400 milliseconds, DTC 61 will set.
