DTC 61

Wiring Diagram:

CIRCUIT DESCRIPTION

When the ignition switch is first turned to "ON" battery voltage is applied to the "AIR BAG" warning lamp and to the "Ignition 1" input terminal "8." The SDM responds by flashing the "AIR BAG" warning lamp seven times. The SDM monitors the lamp driver output by comparing the output state at "AIR BAG Indicator" terminal "7" to the microprocessor commanded state. When "Ignition 1" is above 8.2 volts and the output state does not match the commanded state of the lamp driver for 400 milliseconds DTC 61 is set.

DTC WILL SET WHEN

"Ignition 1" voltage is above a specified value and the output state at the "SIR Indicator" terminal "7" does not match the commanded state of the lamp driver for 400 milliseconds. This test is run every 100 milliseconds during "Continuous Monitoring" tests.

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 to "LOCK."
