DTC 61

Circuit Description
When the ignition switch is first turned ON, Ignition 1 voltage is applied to the indicator lamp and also to the sensing and diagnostic module (SDM) input terminal 10. The SDM responds by flashing the instrument cluster AIRBAG indicator seven times. If the SDM cannot detect voltage on the indicator circuit, a DTC 61 will be set. The SDM also attempts to turn on the AIRBAG indicator, but the indicator will not turn on if inputs have been correctly processed.

DTC 61
DTC 61 will set when, either during the turn-on test or during continuous monitoring, the SDM fails to detect voltage at terminal 7, the input terminal for the AIRBAG indicator.

When DTC 61 is set, the SDM attempts to turn on the AIRBAG indicator.

DTC 61 will clear when the ignition switch is turned OFF or the problem is repaired.

DTC 61 - AIRBAG Warning Lamp Circuit Open

CAUTION: The sensing and diagnostic module (SDM) can maintain sufficient voltage to deploy the airbags for 10 minutes after the ignition is OFF and the fuse has been removed. If the airbags are not disconnected, do not begin service until 10 minutes have passed after disconnecting power to the SDM. Otherwise, injury could result.

CAUTION: During service procedures, 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 SDM arrow must be pointing toward the front Of the vehicle to ensure proper operation of the SIR system. 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.
