● Present/Permanent/Current
● Pending
● History
Present/Permanent/Current codes stored in a control module are used to
help identify the cause of a trouble or troubles with a vehicle. These codes
have occurred a specific number of times and indicate a problem that
requires repair.
Pending codes are also referred to as maturing codes that indicate
intermittent faults. If the fault does not occur within a certain number of drive
cycles (depending on vehicle), the code clears from memory. If a fault occurs
a specific number of times, the code matures into a DTC and the MIL

6.5 Throttle Body Alignment (TPS/TBA)
It’s very common to see a customer pull into the shop with a Volkswagen or
Audi that just will not idle correctly. One of the possible causes is that the
throttle position is not known. When the motion range is not known, the ECU
simply has no idea where to set the throttle. The ECU must know the full
range of motion of the throttle in order for it to properly control the engine.
Using the throttle position sensors in the throttle body, the ECU learns the full
open and full closed positions through various states (idle, part throttle, WOT)
known as a Throttle Body Alignment (TBA).

corresponding cylinder so as to more accurately control or correct cylinder
injection quantity. After the ECU or injector is replaced, injector code of each
cylinder must be confirmed or re-coded so that the cylinder can better identify
injectors to accurately control fuel injection.
6.11 ABS Bleeding
Anytime the brake system is opened to replace components such as calipers,
wheel cylinders, the master cylinder, or brake lines or hoses, air gets inside.
The air has to be removed by bleeding the brakes if you want a firm brake
pedal. Air trapped in the lines, calipers or wheel cylinders will make the pedal
feel soft and spongy. Air is compressible, so when the brakes are applied any
air bubbles in the system must first be compressed before the hydraulic fluid
will transmit pressure to apply the brakes.
