You need someone with actual McLaren Diagnostic tool to scan the car. The McLaren diagnostic tool will point directly to the faulty sensor, circuit, or issue to work on.

AND... It also has guided functions (for many issues - not every issue) that guides the technician exactly where to test the wiring and functions of the system.
