Fault Code Example

Synopsis

Description: This will contain the basic description of the code. If a sensor is mentioned here, it will be a link to a more detailed explaination of it. Otherwise, a related sensor will be linked at the first occurance on the page.

Power loss light: "Off" or "On" will indicate if the "power loss", "limited", or "check engine" light will come on when the code is stored

Limp-in mode: A brief description of what the logic module will do when this code is stored if the sensor is no longer useful.

Possible Causes

Here will be a list of common and/or known causes of this code. For example, you will see this one a lot:

Bad connection or wiring - Check the wiring and connections between the sensor and the logic module (or SMEC). Clean and regrease any corroded connectors with dielectric grease and repair any shorts.

Diagnostic Method

Trigger Parameters

This section will contain a list of all of the events that need to take place for the code to be stored. This should give you a better idea of what is wrong.

Results If Component Fails

What actions the logic module takes when the trigger parameters are met will be described here. There will also be a detailed explaination of the limp-in mode for this sensor, if applicable.

Comments

This section will only be present if there is additional information about this fault code that is useful, but does not fall under any of the above catagories. Again, all related sensors are provided with a link to a page that give a more detailed description of the sensor, how it works, how it is used by the logic module, and how to test them.
