Tracker 4WD V6-2.5L VIN 4 (2001)
IMPORTANT: Do not use a scan tool that displays faulty data. Report the scan tool problem to the manufacturer. Use of a faulty scan tool can result in
misdiagnosis and unnecessary parts replacement.
The provision for communicating with the control module is the Data Link Connector (DLC). The DLC is located under the instrument panel to the right
of the steering column. The DLC is used to connect to a scan tool. Some common uses of the scan tool are listed below:
^
Identifying stored Diagnostic Trouble Codes (DTCS).
^
Clearing the DTCs.
^
Performing output control tests.
^
Reading the serial data.
PCM Service Precautions
NOTE: Turn the ignition OFF when installing or removing the PCM connectors and disconnecting or reconnecting the power to the PCM (battery
cable, PCM pigtail, PCM fuse, jumper cables, etc.) in order to prevent internal PCM damage.
IMPORTANT: Before replacing the Powertrain Control Module (PCM) make sure that the PCM contains the correct calibrations for the model,
equipment, and year of the vehicle being serviced. A PCM incorrectly programmed, or with the wrong calibrations, can set false or incorrect DTCs.
Incorrect calibrations can also cause driveability symptoms and concerns.
The Powertrain Control Module (PCM) is designed to withstand normal current draws associated with vehicle operations. Avoid overloading any circuit.
Do not ground or apply voltage to any of the PCM circuits unless instructed to do so. Do not apply voltage to any of the PCM circuits when testing for
an open or a short in an electrical circuit. The PCM circuits should only be tested using the J 39200 Digital Multimeter (DMM) or an equivalent. The
PCM electrical connectors should remain connected to the PCM during testing.
Aftermarket (Add-On) Electrical And Vacuum Equipment
NOTE:
^
Connect any add-on electrically operated equipment to the vehicle's electrical system at the battery (power and ground) in order to prevent damage
to the vehicle.
^
Do not attach add-on vacuum operated equipment to this vehicle. The use of add-on vacuum equipment may result in damage to vehicle
components or systems.
Aftermarket (add-on) electrical and vacuum equipment is defined as any equipment installed on a vehicle after leaving the factory that connects to the
vehicle's electrical or vacuum systems. No allowances have been made in the vehicle design for addition of this type of equipment.
Add-on electrical equipment may cause the engine control system to malfunction even when the add-on electrical equipment is installed properly.
Portable telephones and radios may also cause engine control system malfunctions even when not connected to the vehicle's electrical system. The first
step in diagnosing any engine control system problem is to remove all aftermarket electrical equipment from the vehicle. Diagnosis may proceed in the
normal manner after eliminating aftermarket equipment as a cause of the engine control system malfunction.
