C1102

Battery Voltage out of Range





DESCRIPTION
The voltage of the HECU power supply drops lower than or rises higher than the specified value.

If the voltage returns to the specified value, this code is no longer output.

CAUTION: If battery voltage drops or rises during inspection, this code will be output as well. If the voltage returns to the standard value, this code is no longer output. Before carrying out the following inspection, check the battery level and refill if necessary.

DTC DETECTING CONDITION:

FAIL-SAFE FUNCTION
Over voltage failure:
System down. both the ABS (TCS) and the EBD function are inhibited and the ABS (TCS) and the EBD warning lamps are activated. In this failure, the valve relay and all solenoids are prevented from being switched on.
Low voltage failure:
1) Outside the ABS control cycle: Inhibit the ABS (TCS) control of front wheels and allow the ABS control of rear wheels, deactivating the motor, and the ABS (TCS) warning lamp is switched on. When the voltage recover to the normal operating range, enable ABS function and ABS (TCS) warning lamp is switched off and erase the error code.
2) Inside the ABS control cycle: Inhibit ABS control of the front wheels and allow ABS control of the rear wheels, deactivating the motor. The ABS (TCS) warning lamp is directly switched on and the state keeps continuously. The error code is always stored.
