Diagnostic Aids Part 2
-
Monitoring the misfire current counters, or misfire graph, may help to isolate the fuel injector that is causing the condition.
-
Operating the vehicle over a wide temperature range may help isolate the fuel injector that is causing the condition.
-
Perform the fuel injector coil test within the conditions of the customer's concern. A fuel injector condition may only be apparent at a certain
temperature, or under certain conditions.
-
If the fuel injector coil test does not isolate the condition perform the fuel injector balance test. Refer to Fuel Injector Balance Test with Special
Tool. See: Computers and Control Systems/Testing and Inspection/Component Tests and General Diagnostics
