RESTRAINT CONTROL SYSTEM
DTC 61 Warning Lamp Circuit Failure
D09RX002
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."
Diagnostic Aids:
Refer to Charts B and C to diagnose warning lamp
circuit malfunctions.
