C1102 CHEVROLET: BATTERY VOLTAGE TOO LOW.
The Hydraulic Electronic Control Unit (HECU) has circuits to perform well. One of these circuits monitors the voltage level available to the HECU, taking into account that, if the voltage level is not necessary, the system cannot guarantee a complete operation.
When the operation of the Anti-lock Braking System (ABS) is required, there are several current requirements that will affect the battery voltage, causing it to drop considerably. Because of this, the voltage is monitored before and during ABS operation to verify that the charging system is in good condition for proper ABS performance.
When the C1102 OBDII diagnostic code is set on your Chevrolet vehicle, it is because the battery voltage is less than 10.5 volts before ABS operation begins. On certain models, this code is also set if the ignition voltage is less than 10.5 volts and the battery voltage is less than 9.0 volts during ABS operation.
The reasons that lead to the DTC C1102 OBD2 code setting on your Chevrolet are:
