Table 3-10. Engine Fault Codes
Description
Supply module heater: Faulty PWM signal
from supply module.
Supply module heater: Dutycycle timing
over error threshold.
Supply module heater: Dutycycle timing out
of valid range.
Diagnostic fault check of short circuit to sup-
ply voltage
(signal range check high) of acceleration
pedal signal.
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
Diagnostic fault check of short circuit to
ground (signal range check low) of accelera-
tion pedal signal
SECTION 3 - CHASSIS & TURNTABLE
Possible Cause
PWM Signal for temperature readout from sup-
ply module to the control unit is not valid.
Supply modul defect, fault in the wiring.
Duty cycle for temperature readout from supply
module to the control unit is out of
range.
Supply modul defect, fault in the wiring.
Duty cycle for temperature readout from supply
module to the control unit is not valid.
Supply modul defect, fault in the wiring.
The signal exceeds the applicatable threshold;
signal range violation
Sensor defect.
Short cut to battery or open loop.
The signal is below the applicatable threshold;
signal range violation
Action
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.
Supply module check and replace if necessary.
Check 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.
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.
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.
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.
