Diagnostics
In the EDC system, there is a diagnostic function that
indicates through a warning light if a fault has occurred.
The following rule of thumb applies when turning the starter
key to the drive position:
The control unit receiving no voltage or the diagnostic lamp
is faulty. Check the EDC system fuses and change where
needed, See the previous page. Check and change the di-
agnostic lamp if needed . Try starting.
Normally, straight after the voltage is turned on and before
the brake test is carried out. The diagnostic lamp should go
out after pressing and holding the brake pedal for a few sec-
onds.
If the light continues to shine then there is a fault in the con-
trol unit which will be working under ”emergency control”.
The engine can be started but it will have a reduced output
and a lower maximum engine speed! Contact your Volvo-
garage as soon as possible.
Fault indication! See next page.
The EDC system monitors the sensors, functions and regu-
lator actuators. Possible faults are stored in the control unit
memory.
Depending on how serious the extent of the fault is, the con-
sequences can lead to reduced engine speed or that the
engine output is reduced.
On constantly: (bus stationary with idling engine)
Flashing:
No light: (directly after the voltage is turned on)
