MOUNT-FLEXIBLE 2W8603 - Caterpillar

Conditions Which Generate This Code:This diagnostic code is designed to indicate a short circuit (high current) in either the solenoid or the wiring for the electronic unit injector for No. 6 cylinder.The Electronic Control Module (ECM) detects the following conditions:
A high current condition (short circuit) for each of five consecutive attempts to operate
Battery voltage above 9 Volts DC for two secondsSystem Response:A warning will appear on the display on the control panel. The warning lamp or the shutdown lamp may illuminate and the warning horn may sound. If equipped, the diagnostic lamp will flash the diagnostic code. The ECM will log the diagnostic code.The engine will have low power and/or rough running.When a cylinder cutout test is performed, a faulty electronic unit injector will indicate a low reading in comparison with the other electronic unit injectors.An electrical fault can prevent the electronic unit injector from operating. A short circuit in the wiring or the ECM that is unique to one electronic unit injector will prevent that individual electronic unit injector from operating. A short circuit in common wiring within the ECM can prevent the three electronic unit injectors that share that common wiring from operating.The ECM will continue to attempt to operate the electronic unit injector after the diagnostic code has been logged but a short circuit will prevent the operation of the electronic unit injector.Test Step 1. Perform the following diagnostic procedure: Injector Solenoid Circuit - TestResults:
