DTC 61

DTC 61 Warning Lamp Circuit Failure




Circuit Description:
When the ignition switch is turned "ON", battery voltage is applied to the "AIR BAG" warning lamp and to the "ignition 1" input terminal "12". The Sensing and Diagnostic Module (SDM) responds by Flashing the "AIR BAG" warning lamp seven times. The SDM monitors the lamp driver output by comparing the output state at "Supplemental Restraint System (SRS) warning lamp" terminal "7" to the microprocessor commanded state. When "ignition 1" is in the specified value, and the output state Does not match the commanded state of the lamp driver for 500 milliseconds, DTC 61 is set.

DTC Will Set When:
"Ignition 1" voltage is in the specified value and the output state at the "SRS warning lamp" terminal does not match the commanded state of the lamp driver for 500 milliseconds. This test is run every 100 milliseconds during "Continuous Monitoring" tests and once per each ignition cycle at the beginning.

Action Taken:
SDM attempts to turn "ON" the "AIR BAG" warning lamp and sets a diagnostic trouble code

DTC Will Clear When:
The ignition switch is turned "OFF."
