Term more commonly known as trouble codes, or DTC’s.
computer self-diagnostics
Glossary “computer self-diagnostics” Definition:
Computer can detect its own problems.
computerize
Glossary “computerize” Definition:
To convert a manual operation into one that is performed by a computer.
computer controlled suspension system
Glossary “computer controlled suspension system” Definition:
System in which a computer-controlled actuator is positioned in the top of each shock absorber or strut. The shock absorber or strut actuators rotate a shaft inside the piston rod, and this shaft is connected to the shock valve. By changing the valve position the performance damping is also changed.

computer controlled brakes
Glossary “computer controlled brakes” Definition:
System having a sensor on each wheel, providing electrical signals into an on-board computer. As the vehicle is stopped, each wheel is stopped or slowed at the same rate, reducing sideways skidding during rapid braking, while maintaining control of the vehicle.
computer controlled dwell
Glossary “computer controlled dwell” Definition:
A system which regulates the length of time that the ignition coil’s primary winding is energized to achieve coil saturation and prevent coil over heating. The leading edge of the trigger signal determines when the coil primary current turns ON, and the trailing edge determines when the coil primary current is turned OFF.
compressor shaft seal
Glossary “compressor shaft seal” Definition:
Assembly consisting of springs, snap rings, O-rings, seal sets, a shaft seal, and a gasket mounted on the compressor crankshaft to permit the shaft to be turned without a loss of refrigerant or oil.
