DTC

C1241/41 Low Battery Positive Voltage or Abnormally High Battery Positive Voltage

DESCRIPTION

The fail-safe function is canceled when the voltage to terminal +BS returns to normal.

HINT:

If the vehicle speed is 20 km/h (12 mph) or less when the battery voltage is low, the ABS warning light

and SLIP indicator light illuminate. However, a DTC will not be output.
