Readiness code

The "readiness code" indicates that the required fault checks were performed by the OBD system. It is not important whether a fault was found. The readiness code is cancelled if the fault memory is erased or the power supply (terminal 30) is cut off with a code stored. The readiness code is not reset when the battery is disconnected if no fault is stored. To initiate the readiness code, at least two trips have to be completed.

For the following systems the "readiness code" is shown:

• Three Way Catalytic Converter (TWC) converting
• Fuel tank ventilation system
• Secondary air injection system
• Oxygen sensor
• Oxygen sensor heating
