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 SDM responds by flashing the
"AIR BAG" warning lamp seven times.
monitors the lamp driver output by comparing the output
state at "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.
The SDM
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."
Diagnostic Aids:
Refer to Charts B and C to diagnose warning lamp circuit
malfunctions.
