🔌 Function

The injector driver controls the high-current injector circuits used by the HPDI system. It receives ECU command signals and triggers the direct injectors at the correct timing and duration for fuel delivery.

Common signs of failure:

• No injector pulse on one or more HPDI injector circuits

• Engine cranks but will not start with verified fuel pressure

• Blown injector-driver fuse or repeated injector circuit fault

• Misfire, dead cylinder or uneven running after injector testing

• HPDI fuel-delivery faults after wiring and ECU checks

• Intermittent shutdown caused by injector-driver heat or internal fault

• Diagnostic fault pointing to injector driver circuit failure

📦 Condition

• Genuine used part

• Removed from running engine where applicable

• In good working condition unless otherwise stated
