READINESS CODE, GENERATING

Test requirements:

^ Fuses for engine electronics OK.

^ Ground (GND) connections at engine and transmission OK.

^ Battery voltage at least 12.7 V.

^ Exhaust system free of leaks.

^ Vehicles with automatic transmission: Selector lever in position "P" or "N".

^ Electrical consumers switched off (radiator fan must NOT run during test).

^ A/C switched off.

^ No DTCs in DTC memory; check DTC memory. "Mode 3: Check DTC memory".

^ Throttle valve angle 10.0 to 20.0%. "Mode 1: Check measuring values"; "PID 17: Throttle valve position (absolute)".

Let vehicle cool off with the ignition switched off until the following conditions are met:

^ Intake air temperature 10 to 50° C. "Mode 1: Check measuring values"; "PID 15: Intake air temperature".

^ Coolant temperature approximately Intake Air Temperature (10 to 50° C). "Mode 1: Check measuring values"; "PID 05: Coolant temperature".

Procedure

WARNING!
To reduce the risk of accident during road tests, always observe safety precautions.

- Connect diagnostic tester.

- Start engine and let run at idle for at least 15 minutes.

- Perform a 15 minute road test in the highest gear or in the highest driving mode on a level driving surface.

The following operating conditions must be met during this road test:

- Engine speed 1800 to 2200 RPM. "Mode 1: Check measuring values"; "PID 12: Engine rotations per minute".

- Vehicle speed constant 90 km/h. "Mode 1: Check measuring values"; "PID 13: Vehicle speed".

- Read readiness code.
