2002 Jeep Liberty KJ Diesel Performance Service Manual – PDF DOWNLOAD
INTRODUCTION :
The procedures contained in this manual include all the specifications, instructions and graphics needed to diagnose engine control module (ECM) and sentry key immobilizer system (SKIS) problems; they are no start, diagnostic trouble code (DTC), and no trouble code problems for the ECM. The diagnostics in this manual are based on the trouble condition or symptom being present at the time of diagnosis.
When repairs are required, refer to the appropriate service information for the proper removal and repair procedure. Diagnostic procedures change every year. New diagnostic systems may be added; carryover systems may be enhanced. IT IS RECOMMENDED THAT YOU REVIEW THE ENTIRE MANUAL TO BECOME FAMILIAR WITH ALL NEW AND CHANGED DIAGNOSTIC PROCEDURES.
This manual will cover all the necessary requirements to begin a logical diagnostic path for each problem. If there is a diagnostic trouble code (DTC) detected, go to the trouble code test. If there are no DTCs present, go to a no trouble code (*), symptom based test. This book reflects many suggested changes from readers of past issues. After using this book, if you have any comments or recommendations, please fill out the form at the back of the book and mail it back to us.
SYSTEM COVERAGE ;
This diagnostic procedures manual covers all 2002 KJ body vehicles equipped with the 2.5L VM diesel engine.
SIX-STEP TROUBLESHOOTING PROCEDURE
Diagnosis of the engine control module (ECM) and sentry key immobilizer system (SKIS) is done in six basic steps:
² verification of complaint
² verification of any related symptom
² symptom analysis
² problem isolation
² repair of isolated problem
² verification of proper operation
NOTE: All tests in this manual should be performed with the engine at operating temperature, unless specified within a particular test.
