929 691 523722 8 Supply module heater: Faulty PWM signal
from supply module. PWM Signal for temperature readout from sup-
ply module to the control unit is not valid.
Supply modul defect, fault in the wiring. Threshold for error detection is an internal ECU
threshold.
When valid Sync followed by temperature
information signal is received AND valid sync
and temperaturesignal for both information is
received one after the other.
Supply module check and replace if necessary.
Check the wiring.
930 689 523721 8 Supply module heater: Dutycycle timing
over error threshold. Duty cycle for temperature readout from supply
module to the control unit is out of
range.
Supply modul defect, fault in the wiring. Supply module check and replace if necessary.
Check the wiring.
931 689 523721 8 Supply module heater: Dutycycle timing out
of valid range. Duty cycle for temperature readout from supply
module to the control unit is not valid.
Supply modul defect, fault in the wiring. When the received supply module duty cycle
SCR_rSMT is in the valid range
(SCR_rSMTVld-Min_C <= SCR_rSMT <=
SCR_rSMTVldMax_C), OR in the failure
range (SCR_rSMFailMin_C <=SCR_rSMT <=
SCR_rSMFailMax_C)
Supply module check and replace if necessary.
Check wiring.
932 1-2-6 29 3 Diagnostic fault check of short circuit to sup-
ply voltage
(signal range check high) of acceleration
pedal signal. The signal exceeds the applicatable threshold;
signal range violation If the signal is below the applicatable threshold
APP_uRawSRCHiHTLIS_C, the signal
range violation is reset
after the healing debouncing.
In case when the CCP is active (CCP_stActive =
1)and the reading from the EEPROM
memory is successful, the
signal is below the threshold
APP_uHTLISCCPHi[1], a signal range violation
is reset
after debouncing.
935 2-2-6 91 3 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 Sensor defect.
Short cut to battery or open loop. Check cabling, check accelerator pedal sensor
and if necessary replace it, check
connection cable and if necessary repair or
replace it.
If the signal is below the applicatable threshold
APP_uRaw1SRCHigh_C, the signal
range violation is reset after
the healing debouncing.
937 1-2-6 29 4 Diagnostic fault check of short circuit to
ground (signal range check low) of accelera-
tion pedal signal The signal is below the applicatable threshold;
signal range violation If the signal exceeds the applicatable threshold
APP_uRawSRCLoHTLIS_C, the signal
range violation is reset
after the healing debouncing.
In case when the CCP is active (CCP_stActive =
1)and the reading from the EEPROM
memory is successful, the
signal exceeds the threshold
APP_uHTLISCCPLo[1], a signal range violation
is reset
after debouncing.
