Description
Start relay (low side power stage): the cur-
rent drain measured by ECU is above the
tar- get range.
Start relay (high side power stage):
the current drain measured by ECU is above
the target range.
Start relay (low side power stage): the cur-
rent drop measured by ECU is above the
tar- get range.
Start relay (low side power stage): the cur-
rent drop measured by ECU is above the
tar- get range
Start relay (low side power stage): the cur-
rent drop measured by ECU is above the
tar- get range.
Supply module heater: PWM time period
out of valid range.
wiring to the intake air heater device is
faulty.
wiring to the air intake heater is faulty
Possible Cause
Shortcut LowSide-Output to battery.
Shortcut HighSide-output to ground.
Shortcut LowSide-Output to ground.
Open circuit/disconnection LowSide-Output.
Temperature over limit.
PWM signal for temperature readout from
sup- ply module to the control unit is out of
range.
Supply modul defect, fault in the wiring.
Intake Air Heater Device: overload, short-
circuit
Relay (for cold start aid) cable break or short to
ground:
Action
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.
