In the ON position, the ignition switch applies battery voltage to the AIR BAG warning lamp and to the IGNITION 1 input terminal 10. The inflatable restraint sensing and diagnostic module (SDM) responds by flashing the AIR BAG warning lamp 7 times. The SDM monitors the lamp driver output by comparing the output state at the AIR BAG INDICATOR CONTROL terminal 7 to the microprocessor commanded state.
The output state at the INFLATABLE RESTRAINT INDICATOR terminal 7 does not match the commanded state of the lamp driver for 400 milliseconds.
The CONTINUOUS MONITORING test inspects for this DTC. This test occurs when IGNITION 1 is within the normal operating voltage range.
• | The SDM sets a diagnostic trouble code. |
• | The SDM attempts to turn ON the AIR BAG warning lamp. |
• | Current DTC--The output state at the INFLATABLE RESTRAINT INDICATOR terminal 7 matches the commanded state of the lamp driver for 400 milliseconds. |
• | History DTC |
- | You issue a scan tool CLEAR CODES command. |
- | After 250 malfunction free ignition cycles have occurred. |
