Simulating fault causes

A large amount of input data is a required to recreate and simulate fault occurring circumstances.

Certain cases can be difficult to recreate. High speed driving and stalling to achieve high loads is not recommended.

In order to achieve high loads accelerate hard in quick succession a number of time instead.

Cases that are possible to simulate:

• high load
• moisture
• heat
• cold
• loose connections.

High load 

High load can be simulated by accelerating hard repeatedly.

Moisture 

Moisture can be simulated by spraying water on the suspected faulty component or connector using a spray bottle or hose.

Heat 

Heat can be simulated by using a hot air gun or similar to heat up a suspected faulty component or connector.

In order to achieve a high engine temperature allow the engine to idle at a high load with the hood down to prevent air flowing through the engine compartment. Run the engine in hot conditions. Read off the engine coolant temperature (ECT) using VIDA, the temperature gauge in the combined instrument panel is progressive.

Cold 

Cold can be simulated by cooling down the suspected faulty component or connector using a freeze spray.

Loose connections 

Loose connections can be simulated by twisting and shaking the connector whilst the function is activated.
