π Two days of diagnostics to unravel multiple faults in this Aston Martin audio system.
We had this 2009 Aston Martin in the workshop after the audio system suddenly went from working normally to completely dead.
With the vehicle reporting a break in the MOST fibre-optic network, the only way to find the cause was to work through the system properly, module by module.
β
Every audio module located and uncovered
β
Interior panels and facias carefully dismantled
β
MOST fibre-optic network visually inspected
β
Modules tested and bypassed individually
β
Rear wheel arch modules accessed and checked
β
Multiple faults eventually identified
During testing we found evidence of water ingress around the modules located in the rear wheel arch, along with a fault involving the FM tuner.
However, even after bypassing those sections, the audio system still refused to come back to life.
So the search continued.
After working further through the vehicle and removing the subwoofer, we finally uncovered an old aftermarket iPod interface hidden away in the system.
Once that module was bypassed, we finally restored the MOST network and brought the audio system back to life. π
Two days of tracing fibre optics, uncovering modules and eliminating faults one by one β and now, once the replacement parts arrive, weβve got another full day of carefully putting the car back together again! π
Electrical and audio faults like this arenβt always solved with a diagnostic computer. Sometimes you have to physically trace the entire network until every fault has been found and proven.
Got an audio or electrical fault that nobody seems to be able to pin down? Drop us a message.
