Symptom
Rough running and safe mode. Autocom indicated faults relating to both camshafts.
Diagnostic direction
Indications involving both camshafts need to be considered alongside the symptom and mechanical timing. A scan-tool indication alone does not prove failure of a particular component.
Checks and available evidence
Incorrect mechanical timing was confirmed after inspection. The inspection method, numerical measurements and exact codes were not supplied and are not added here.
Final confirmed finding
Final confirmed finding: incorrect engine mechanical timing. A specific repair has not been supplied for publication.
Limits of this case
This case is not an automatic diagnosis for another vehicle. The specific vehicle, ECU, measurements and official manufacturer procedure must be considered together. Only the available confirmed facts are published; diagnostic directions do not describe additional work documented in this case.
