Fault Codes
Rheostat Control
When the ECU had discovered a fault, the rheostat control will flash a fault
code. The control should therefore be ideally placed where it can be clearly
seen and accessed.
The faults will be displayed as short flashes followed by long flashes. To
determine the code, you must count the number of long flashes.
