Readiness code, generating: Procedure

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

Coolant temperature must reach at least 80 ° C, see DIAGNOSTIC MODE 1: CHECK MEASURED VALUES ; PID 5, Coolant temperature.

Observe the safety precautions that apply to road tests, see SAFETY PRECAUTIONS .

Let vehicle cool off with the ignition switched off until the following condition is met:

Coolant temperature approx. intake air temperature (5 to 35 ° C), see DIAGNOSTIC MODE 1: CHECK MEASURED VALUES ; PID 5, Coolant temperature.

Perform a road test anew.
The following operating conditions must be met during this road test:
Accelerate vehicle uniformly, not at Wide Open Throttle (WOT).
Drive for 10 minutes in the highest gear or in the highest driving mode on a level driving surface at a constant speed in the range of 65 to 80 km/h at an engine speed of 2000 to 2500 RPM.
NOTE:
- Vehicle speed, see DIAGNOSTIC MODE 1: CHECK MEASURED VALUES ; PID 13, Vehicle speed.
- Engine speed, see DIAGNOSTIC MODE 1: CHECK MEASURED VALUES ; PID 12, engine rotations per minute (RPM).
After 10 minutes, downshift until an engine speed of 2800 to 3500 RPM has been reached.
Drive in deceleration mode at a speed up to approx. 1800 RPM.
Park vehicle and let engine run at idle for 3 minutes.
- Accelerator pedal must not be operated during this time.
Perform a road test anew.
