Who needs this CAT C10 0006-11 manual
Diesel mechanics and workshop owners troubleshooting a Cylinder #6 injector current fault on 3406E, C-10, or C-12 engines need this guide. It is essential for anyone diagnosing DTC PID 0006 FMI 11 and dealing with engine misfires or low power conditions linked to injector solenoid circuit problems.
According to the document, the Engine Control Module (ECM) logs this diagnostic code when it detects either a low current (open circuit) or high current (short circuit) condition in the Cylinder #6 injector solenoid wiring. When active, the ECM illuminates the check engine lamp and triggers a snapshot. The automatic Cylinder Cutout Test is disabled while the code remains active. Performance symptoms include engine misfires and low power, because the affected injector may not operate at all. The prescribed resolution is Test Step 1: perform the “Injector Solenoid Circuit – Test” diagnostic procedure. If the result is OK, no further action is required.
