Tribute 2WD V6-3.0L (2008)
Engine Control Module: Procedures
Clear the Continuous Diagnostic Trouble Codes (DTCs) and Reset the Emission Monitors
Information In the PCM
Clear the Continuous Diagnostic Trouble Codes (DTCs) and Reset the Emission Monitors Information in the Powertrain Control Module
(PCM)
Description
All on board diagnostics (OBDII) scan tools support the clearing of continuous DTCs and resetting of emission monitors information in the PCM.
The clearing of the continuous DTCs allows the scan tool to command the PCM to clear/reset all emission-related diagnostic information. While carrying
out this operation DTC P1000 is stored in the PCM until all the OBD system monitors or components have been tested to satisfy a drive cycle without
any other concerns occurring.
The following events occur when the continuous DTCs and the emission monitors information is cleared from the PCM:
-
The number of DTCs and the DTCs
-
The freeze frame data
-
The diagnostic monitoring test results
-
The status of the OBD II system monitors is reset
-
DTC P1000 is set
NOTE: This function is carried out only after retrieval of continuous DTCs.
Resetting the Keep Alive Memory (KAM)
Resetting The Keep Alive Memory (KAM)
Description
Resetting the KAM returns the PCM memory to its default setting. Adaptive learning contents such as adaptive airflow, idle speed, refueling event, and
fuel trim are included. Clear the continuous DTCs in the PCM and reset the emission monitors information, is part of a KAM reset.
After the KAM has been reset, the vehicle may exhibit certain driveability concerns. It is necessary to allow the engine to idle at normal operating
temperature with the air conditioning (A/C) OFF for 2 minutes. Then drive the vehicle to allow the PCM to learn the values for optimum driveability
and performance.
This function may not be supported by all scan tools. Refer to the scan tool manufacturer's instruction manual.
If an error message is received or the scan tool does not support this function, disconnecting the battery ground cable for a minimum of 5 minutes may
be used as an alternative procedure.
A KAM Reset is done as follows:
During key on, engine off with the scan tool, use the reset keep alive memory function. This is found in the active command modes menu on the
Integrated Diagnostic System (IDS) scan tool.
If a generic scan tool is used, this function may not be supported. See scan tool manufacturer's instruction manual.
If an error message is received or the scan tool does not support this function, disconnecting the negative battery cable for a minimum of 5 minutes may
be used as an alternative procedure.
