2.12.7 Diagnostic Information and Procedures
2.12.7.1 Diagnosis Description

Before carry out the control system diagnostic. Refer to

2.12.2

Description and Operation

and

2.12.3

System Working Principle

Understand and get familiar with control system working principle, and then start systematic diagnostic, so that it will help to determine
the correct diagnostic steps, more importantly, it also help to determine whether the customer described situation is normal.

Before any control system fault diagnostic, using the

2.2.7.2

Control System Check

as a starting point to guide the servie personnel

to take the next logical step for fault diagnosis. Understand and correctly use the diagnostic flow chart can reduce the diagnostic
time and avoid misjudge on components.

2.12.7.2 Control System Check

For 4G15-D engine control system check. Refer to the 4G18-D engine

2.2.7.2

Control System Check

2.12.7.3 Intermittent Fault Check

For 4G15-D engine intermittent fault check, please refer to the 4G18-D engine
