Normal Operation

When the ignition is turned to the ON position, the solenoids are set to the maximum ambient temperature stored in the anti-lock brake system (ABS) module from the last ignition switch cycle. The temperature of the solenoid is updated every 6 milliseconds. This temperature is an estimate based on the amount of time the solenoid is on or off. Temperature increases with the solenoid on and decreases with the solenoid off.
