Basic Setting (Function 04)
NOTE:
- Basic setting is carried out with engine running.
- The OBD II engine control module shows the "Readiness Code" in display group 29. The readiness code is reset when the engine control module power is off and each time the DTC memory is erased. In order to regenerate the readiness code it is necessary to take a trip in "mixed city and highway" driving-approx.1-1/2 to 5 minute drive at 80 - 100 km/h (50-63 mph) with manual transmission in 4th or 5th gear, preferably 4th gear, or automatic transmission selector lever in "D" position.
- When the "Basic Setting" function 04 is initiated with the VAG 1551 scan tool, the learning values are relearned in systems capable of learning. Learning is prohibited, as soon as a malfunction is stored in the DTC memory that relates to a system capable of learning (not with sporadic malfunctions).
- All learning values are erased by disconnecting the connector from the Engine Control Module (ECM). After that, uneven idle can occur briefly. In this case, let engine run in idle for a few minutes until the learning process is completed.
After function 04 is called up, the Engine Control Module (ECM) carries out the following operations;
- Constant ignition timing point of 12° BTDC is output in idle.
- Digital idle speed control is blocked.
- Evaporative emissions canister purge regulator valve is closed.
- A/C compressor is switched off.
- EGR vacuum regulator solenoid valve is closed
- No coolant temperature correction-fixed value of 80 °C (176 °F)
- Learning values are relearned (idle and CO content are adjusted automatically)
Requirements:
- Engine temperature at least 85 °C (185 °F)
- Do not operate accelerator pedal
- All electrical consumers switched off
- A/C system switched off. Push minus (-) button for A/C fresh air fan repeatedly until all the displays are cleared
- Move selector lever to P or N
- No malfunctions in Diagnostic Trouble Code (DTC) memory
- Check and erase DTC memory.
- There must be no malfunctions stored (if necessary repair malfunction, erase DTC memory and test drive, switch engine off and start again, test drive and, as a check, check DTC memory again).
NOTE: The readiness code is erased each time the DTC memory is erased (either with function 05 or with Mode 4).
- After checking and erasing DTC memory, let engine continue to run at idle.
