  1. Trouble Codes
  1. The [Trouble Codes] function read diagnose trouble codes from the vehicle's computer modules; include two types of codes: Malfunction Indicator Lamp (MIL) codes and pending codes.
  2. MIL Codes: These codes cause the computer to illuminate the MIL when an emission related or drivability fault occurs. The MIL is also known as the “Service Engine Soon” or “Check Engine Lamp”. MIL codes remain in the vehicle’s memory until the fault is repaired.
  3. Pending Codes: These codes are also referred as “continuous monitor” and “maturing codes”. An intermittent fault will cause the computer to store a code in memory. If the fault does not occur within 40 warm-up cycles, the code will be cleared from memory. If the fault is occurred a specific number of times, the code will mature into a DTC and the MIL will turn on.
  4. Operation is just like the [Read DTC] in [HD OBD II].
  1. Erase Codes
  1. The [Erase Codes] function erases Fault Code from the vehicle's computer.
  2. Operation is just like the [Clear DTC] in [HD OBD II].

  2. Operation is just like the [Read Data] in [HD OBD II].
