Preface

This document is designed to be used for safe and correct diagnosis of the electrically

controlled DAEWOO Diesel DL08 and DV11 engine.

It is recommended that all information in this manual as well as the engine service man-

ual and electrical wiring diagrams be fully understood before diagnosis with the diagno-

sis device (SCAN200) for accurate and effective service and shorter service hours.

If there is any incorrect information or type in this manual, feel free to contact Daewoo

Bus Corporation.

The specifications contained in this manual are subject to change without notice.

We hope this manual will help your service.

System Diagnostic Manual

1. Diagnositc device for system There are two ways to check DTCs of the DL08 and DV11 engines for the purpose of diagnosis: using the diagnosis device (SCAN-200) and checking the blinking number of the engine CHECK lamp.

This manual mainly describes diagnosis procedures with the device (SCAN-200) for faster and accurate diagnosis.
