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 A1. 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 Will Set When
Either during the turn on test or during continuous monitoring, the SDM fails to detect voltage at terminal A9, the input terminal for the AIRBAG indicator.

Action Taken
The SDM attempts to turn on the AIRBAG indicator, and it sets a DTC 61.

DTC 61 Will Clear When
The ignition switch is turned OFF or the problem is repaired.

DTC 61 - AIRBAG Warning Lamp Circuit Failure

CAUTION: The 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 air - bags are not disconnected, service cannot begin until 10 minutes have passed after disconnecting power to the SDM.

CAUTION: During service procedures, be very careful when handling the SDM. Never strike or jar the SDM.

Never power up the SIR system 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.
