The ECM’s role is to measure the coolant’s temperature and adjust the coolant’s temperature accordingly. When the coolant temperature drops too low, the oil in the steering module hardens, resulting in a harder steering wheel. Upon occurrence, the steering assist is activated by adding greater force to the steering wheel.
