Description of functions

The ABS motor relay is integrated into the brake actuator assembly.

The skid control computer (brake actuator assembly) turns on the ABS motor relay to operate the pump motor in the brake actuator assembly while ABS, TRC, Vehicle stability control, or brake assist is operating.

If the power supply voltage for the ABS motor relay drops due to insufficient output of the battery or alternator, this code may be stored in memory.
