Each injector has a unique 10 digit code representing the flow characteristic of that injector. The IQA code is located on each injector head and is also printed on a factory label located on the engine. The factory installed label indicates the IQA data for all the original injectors installed at the factory. In addition, there are individual injector IQA labels provided with each service replacement injector.
Refer to both the factory label and the individual service labels to obtain the latest IQA data. If the labels are missing or damaged retrieve the IQA data from each injector head.
When an injector is replaced, program the IQA code for the injector using the IDS. The IDS will automatically clear the keep alive memory values associated with the old injector when the new injector IQA code is entered.
The new injector IQA sticker must be affixed next to the old sticker.
Note: If an injector is being swapped to a different cylinder the IQA number must be programmed.
