Fault lamp for electric throttle
control K132
Faults in the Electronic Accelerator System are
detected by the self-diagnosis and indicated
via the separate EPC fault lamp. At the same
time, an entry is made in the fault memory.
When the ignition is turned on, the fault lamp
comes on and must go out again after 3
seconds if a fault state does not exist.
Fault lamp K132 is activated directly by the
engine control unit via an earth potential.
If a fault occurs in the Electronic Accelerator
System, an appropriate emergency running
program will be activated (refer to Accelerator
position sender and throttle valve control part).
