Why do you have to code injectors?
Coding an injector is a vital part of the testing and repairing of injectors, and provides an essential connection between the physical injector firing events and the digital Electronic Control Unit (ECU) of the vehicle’s engine.
How much does ECM cost?
The cost for the new ECM will typically be around $800, with labor around $100, bringing the average total expense for an ECM replacement to approximately $900 before taxes and fees. This can increase depending on the shop you go to or the type of car you, running as high as $2,000.
Where is the injector information stored in the ECM?
The control functions for the fuel injection system are integrated in the engine control module (ECM). Each injector’s flow rate information and cylinder position are stored in the memory of both the glow plug control module (GPCM) and the ECM.
How to update gpcm flow rates when replacing injectors?
⇒ If any injectors are replaced, go to Reprogram Injector Flow Rates parameter and enter the flow rate number of the new injector to the corresponding cylinder. The flow rate numbers will automatically update both control modules. ⇒ If the ECM was replaced, go to Copy GPCM Flow Rates to ECM parameter and reprogram the ECM.
Where do I enter the injector correction code?
Injector barcode settings In the “New Barcode” field, enter the injector correction code for the corresponding cylinder. After the injector correction code has been entered, select “Apply” to proceed according to the procedure prompt until you see the message that the new correction code was successfully sent to the ECM.
When do you change the fuel injector flow rate?
The fuel injector flow rate programming must be done when any of the following procedures are performed: The ECM is replaced. The GPCM is replaced. Any fuel injectors are replaced. If the ECM does not communicate, the flow rate information can be retrieved from the GPCM.
