Diesel Diagnostics

Advanced diesel diagnostics in Langley, BC including drivability, electrical, fuel pressure, boost, intermittent faults and in-house chassis dyno testing.

Drivability diagnostics

A truck that only acts up while accelerating, towing or at highway speed may test normally in the bay. We use live data and road-load testing to reproduce the complaint.

Electrical diagnostics

Instead of replacing modules or sensors because a code names them, we can check powers, grounds, circuits, network communication and the inputs that caused the code.

Fuel pressure diagnosis

We compare commanded and actual pressure and test the supply and high-pressure sides to determine whether the problem is delivery, leakage, control or a failed component.

Turbo and boost diagnosis

Smoke or low power is not automatically a bad turbo. Airflow, boost leaks, actuator operation, exhaust restriction and sensor data all matter to the diagnosis.

Intermittent fault diagnosis

Intermittent problems take time and the right conditions. Our goal is to duplicate the fault and capture useful data instead of sending the vehicle out with an unproven guess.

Chassis dyno diagnostics

Our in-house chassis dyno lets us load the vehicle in a controlled environment when the fault appears only under road conditions.
