Failure Conditions

DTC 25 will set when the 36 VLR power supply in the SDM is in its normal operating voltage range and neither of the two inflator modules is open and the voltage measured at "Driver Side LO" and "Passenger Side LO" is within a specified range. Once these conditions are met the SDM will ground "Driver Side LO" and "Passenger Side LO" through a resistor and check that Ignition 1 is in the normal operating voltage range. When all previous conditions are met and the voltage measured at "Driver Side LO" and "Passenger Side LO" is above a specified value.
