2003 Jeep Liberty KJ Body Service Manual – PDF DOWNLOAD
INTRODUCTION:
The procedures contained in this manual include all the specifications, instructions, and graphics needed to diagnose 2003 body system problems. The diagnostics in this manual are based on the failure condition or symptom being present at the time of diagnosis. Please follow the recommendations below when choosing your diagnostic path.
1. First make sure the DRBIIIt is communicating with the appropriate modules; i.e., if the DRBIIIt displays a “No Response” condition, you must diagnose that first.
2. Read DTC’s (diagnostic trouble codes) with the DRBIIIt.
3. If no DTC’s are present, identify the customer complaint.
4. Once the DTC or customer complaint is identified, locate the matching test in the Table of Contents and begin to diagnose the symptom. All component location views are in Section 8.0. All connector pinouts are in Section 9.0. All schematics are in Section 10.0. An * placed before the symptom description indicated a customer complaint.
When repairs are required, refer to the appropriate service manual for the proper removal and repair procedure. Diagnostic procedures change every year. New diagnostic systems may be added: carryover systems may be enhanced. READ THIS MANUAL BEFORE TRYING TO DIAGNOSE A VEHICLE DIAGNOSTIC TROUBLE CODE.
It is recommended that you review the entire manual to become familiar with all new and changed diagnostic procedures. This book reflects many suggested changes from readers of past issues. After using this book, if you have any comments or suggestions, please fill out the back of the book and mail it back to us.
