DTC 41 IG Power Source Circuit
CIRCUIT DESCRIPTION
This is the power source for the ECU, hence the actuators.
DTC No.DTC Detecting ConditionTrouble Area
41
Detection of any conditions from 1. through 3.:
1. Vehicle speed is 3 km/h (1.9 mph) or more and battery
voltage is less than 9.5 V continues for 10 sec. or more.
2. Battery voltage has never exceeded more than 17.0 V
and has become less than 9.5 V within 2.16 sec., under
malfunction of solenoid relay monitor after the solenoid
relay is ON, at ECU AST terminal voltage of ECU has
become 8.0 V or more or under malfunction of motor
relay monitor and after the motor relay is ON, motor
relay monitor has become ON.
3. Battery voltage is more than 17.0 V , which continues for
1.2 sec. or more or battery voltage has become more
than 17.0 V within 2.16 sec. and solenoid or motor relay
monitor is under malfunction condition.
Battery
Charging system
Power source circuit
ECU
Fail safe function:
If any trouble occurs in the power source circuit, the ECU cuts off current to the ABS & TRAC solenoid relay
and prohibits ABS control and TRAC control.
