Opel Corsa B - the Repair manual and operation

1.9. Diagnostics of malfunctions

The description of diagnostics of electronic control systems and diagnostic codes are provided in the Head Sistemy of electric equipment of the engine.

In this Section the simplest scheme of clarification of the reasons of the malfunctions and refusals happening in knots and systems of the vehicle is offered. Refusals and their possible reasons are broken into groups on a sign of the relation to certain components or systems of the car, such as the engine, the cooling system, etc., besides, in the text references to Chapters and Sections concerning these problems are given.

Remember that the successful completion of search of causes of defect is not the black magic available only to skilled professional mechanics at all, and is defined by a combination of a certain knowledge and patient, systematic approach to a problem research. It is necessary to move always from simple to difficult, to bring each check to the logical end and to try not to pass the obvious facts - everyone can forget to fill fuel in the fuel tank or to leave included in lighting fixtures for the night.

And at last, it is always necessary to try to make a clear picture of development of malfunction and to take the corresponding steps for prevention of a recurrence. If the failure of electric equipment happened for a cause of infringement of quality of contact, check a condition of all other contacts and electric sockets of system at the same time. If the same safety lock several times in a row continues to fuse, there is no sense in its further replacement - it is necessary to try to find out a cause of failure. Remember that failure of a minor component can be a sign of violation of functioning of more important knot or the whole system.

Engine

If the engine is not started, it is necessary to analyse a situation. That the engine in general could be started, two main conditions have to be satisfied. Air-fuel mix has to come to cylinders, and on a spark plug the spark has to be developed. Therefore, first, it is necessary to check whether fuel moves. As at the same time it is necessary to work, it is described in the Head of the Power supply system, release and decrease in toxicity of the fulfilled gases.

To define whether the spark is developed, it is necessary to turn out candles, to insert into tips and to put separately to weight. At the same time you do not hold a tip or a cable of ignition with hands, and use well isolated nippers. Ask the assistant to start the engine. If the spark is absent, define a cause of failure, being guided by the Head Sistemy of electric equipment of the engine.

Procedures of diagnostics of an electronic control system and codes of malfunctions are provided in the Head Sistemy of electric equipment of the engine.
