Diagnostic Trouble Code (DTC) 55
Driver Side Airbag Deployment Loop is Shorted to Power
Circuit Description
When the ignition switch is turned to ON, the sensing and diagnostic module(SDM) will perform turn-on test to diagnose critical malfunctions within SDM itself.
Upon passing these test ignition and deployment loop voltages are measured to ensure that they are within their normal voltage ranges. The SDM monitors the voltages at the driver low and the passenger low to detect shorts to ground or voltage in the deploy loops.
The SDM checks the wiring connection to the driver side airbag module by letting the infinitesimal current flow through the internal circuit and verify the resistance.
DTC 55 Will Set When
- The side airbag wiring of driver's high is shorted to battery wiring.
- The side airbag wiring of driver's low is shorted to battery wiring.
DTC 55 – Driver Side Airbag Deployment Loop Is Shorted To Power
Caution : The sensing and diagnostic module(SDM) can maintain sufficient voltage to deploy the airbags and pretensioners for 1 minute after the ignition is OFF and the fuse has been removed. If the airbags and pretensioners are not disconnected, do not begin service until one minute has passed after disconnecting power to SDM. Otherwise, injury could result.
Caution : During service procedure, be very careful when handling the SDM. Never strike or jar the SDM. Never power the supplemental inflatable restraints(SIR) when the SDM is not rigidly attached to the vehicle. All SDM mounting bolts must be carefully tightened , and the arrow on the SDM must be point toward the front of the vehicle to ensure proper operation of the SIR. The SDM could be activated if it is powered when it is not rigidly attached to the vehicle, resulting in unexpected deployment and possible injury.

Diagnostic Trouble Code (DTC) 87
Passenger Side Airbag Sensor Failure
Circuit Description
When the ignition switch is turned to ON, the sensing and diagnostic module(SDM) will perform turn-on test to diagnose critical malfunctions within SDM itself.
Upon passing these test ignition and deployment loop voltages are measured to ensure that they are within their normal voltage ranges. The SDM monitors the voltages at the driver low and the passenger low to detect shorts to ground or voltage in the deploy loops.
DTC 87 Will Set When
- The the passenger side airbag sensor is inoperative.
DTC 87 – Passenger Side Airbag Sensor Failure
Caution : The sensing and diagnostic module(SDM) can maintain sufficient voltage to deploy the airbags and pretensioners for 1 minute after the ignition is OFF and the fuse has been removed. If the airbags and pretensioners are not disconnected, do not begin service until one minute has passed after disconnecting power to SDM. Otherwise, injury could result.
Caution : During service procedure, be very careful when handling the SDM. Never strike or jar the SDM. Never power the supplemental inflatable restraints(SIR) when the SDM is not rigidly attached to the vehicle. All SDM mounting bolts must be carefully tightened , and the arrow on the SDM must be point toward the front of the vehicle to ensure proper operation of the SIR. The SDM could be activated if it is powered when it is not rigidly attached to the vehicle, resulting in unexpected deployment and possible injury.
