updates the Failure Records.
* The following applies to misfire DTCs:
- If the control module detects a low level or an emission level misfire condition during 2 consecutive trips, the control module illuminates
the MIL.
- If the control module detects a high level or catalyst damaging misfire, the control module flashes the MIL at a rate of once per second.
- If the control module detects a misfire during 2 non-consecutive trips, the stored conditions are compared with the current conditions. The
control module illuminates the MIL when the following conditions occur:
* The engine load is within 20 percent of the previous test that failed.
* The engine speed is within 375 RPM of the previous test that failed.
* The engine coolant temperature is in the same range of the previous test that failed.
* The following applies to fuel trim DTCs:
- If the control module detects a fuel trim condition during 2 consecutive trips, the control module illuminates the MIL.
- If the control module detects a fuel trim condition during 2 non-consecutive trips, the stored conditions are compared with the current
conditions. The control module illuminates the MIL when the following conditions occur:
* The engine load is within 20 percent of the previous test that failed.
* The engine speed is within 375 RPM of the previous test that failed.
* The engine coolant temperature is in the same range of the previous test that failed.
Conditions for Clearing the MIL/DTC - Type A or Type B
* The control module turns OFF the MIL after 4 consecutive ignition cycles that the diagnostic runs and does not fail.
* A current DTC, Last Test Failed, clears when the diagnostic runs and passes.
* A history DTC clears after 40 consecutive warm-up cycles, if no failures are reported by this or any other emission related diagnostic.
* Clear the MIL and the DTC with a scan tool.
Non-Emissions Related DTCs
Action Taken When the DTC Sets - Type C
* The control module stores the DTC information into memory when the diagnostic runs and fails.
* The MIL will not illuminate.
* The control module records the operating conditions at the time the diagnostic fails. The control module stores this information in the Failure
Records.
* The driver information center, if equipped, may display a message.
Conditions for Clearing the DTC - Type C
* A current DTC Last Test Failed clears when the diagnostic runs and passes.
* A history DTC clears after 40 consecutive warm-up cycles, if no failures are reported by this or any other non-emission related diagnostic.
* Clear the DTC with a scan tool.
Action Taken When the DTC Sets - Type D
* The control module will take default actions but no DTC will be stored in Failure Records.
* The MIL or SVS will not illuminate.
Conditions for Clearing the DTC - Type D
Clear the DTC with a scan tool.
