C1242

DTC C1241/41 Low Battery Positive Voltage
DTC C1242/42 Open in IG1/IG2 Power Source Circuit

DESCRIPTION

DTC DETECTION CONDITION:

These codes are memorized when the power source voltage for the skid control ECU drops or the voltage for the ABS No. 1, ABS No. 2 relay operation drops. Codes may be memorized when the voltage of the auxiliary battery temporarily drops. When the power source voltage is too high, the skid control ECU stops functioning and outputs no DTCs, and the ABS and BRAKE warning lights remain on.

HINT: DTC C1256/56 (accumulator low voltage malfunction) may be memorized if the power source voltage drops.
