Description
Analog accelerator pedal sensor 1 or double
accelerator pedal sensor: the voltage mea-
sured by ECU is out of the target range or the
calculated pedal position is implausible
compared with the position of the second
pedal
Internal hardware monitoring: the ECU
detects a deviation of the target range of the
power supply voltage of sensor output 1.
Internal hardware monitoring: the ECU
detects a deviation of the target range of the
power supply voltage of sensor output 2.
Internal hardware monitoring: the ECU
detects a deviation of the target range of the
power supply voltage of sensor output 3.
Start relay (high side power stage): the cur-
rent drop measured by ECU is above the tar-
get range.
Possible Cause
Short circuit to ground.

Action
Check cabling, check accelerator pedal sensor
and if necessary replace it, check
connection cable and if necessary repair or
replace it
If the signal exceeds the applicatable threshold
APP_uRaw1SRCLow_C, the signal
range violation is reset after the
healing
Check cabling of external components, check
working voltage and if necessary correct
it,
check connection cable and if necessary repair
or replace it,
if error is not removable, change ECU.
Check cabling of external components, check
working voltage and if necessary correct

repair or replace it, if error is not removable,
change ECU.
Check cabling of external components, check
working voltage and if necessary correct
it,
check connection cable and if necessary repair
or replace it,
if error is not removable, change ECU.
Threshold for error detection is an internal ECU
threshold.
Check cabling and start relay and if necessary
replace it,
check connection cable and if necessary repair
or replace it.
