Customer concern or upgrade request
An Engine Control Module no-response fault prevented reliable communication with the engine management system.
Inspection and diagnosis
The workshop inspected the wiring harness, tested continuity and checked ECU communication and connector integrity. The record identifies wiring or connection faults but does not specify an individual wire or pin.
Repair and upgrade work
The vehicle presented with an Engine Control Module (ECM) no-response fault, preventing reliable communication with the engine management system. Our technicians carried out a full wiring harness inspection and ECU connectivity check, tracing the fault through the vehicle's electrical architecture to identify the root cause rather than replacing components unnecessarily.
- Full-system diagnostic scan and fault code retrieval
- Wiring harness inspection and continuity testing
- ECU communication and connector integrity check
- Targeted repair of identified wiring or connection faults
Testing and verification
Live-data verification and a post-repair road test confirmed normal engine management operation after ECM communication was restored.
Documented outcome
ECM communication restored and the no-response fault cleared. The engine management system returned to normal operation after verification with live data and a post-repair road test.
