How to use the NOx sensor emulator NOXEM 129 | 130. Part 2
We recommend using INPA for re-adaptation of the engine. Alternative: ISTA D/+
Re-adaptation of the engine using INPA
Note: INPA loader 2.023 required.
Switch on the ignition (engine off), connect OBD to USB connecting cable:
a) do not press any pedal (no clutch, no brake pedal);
b) press the ‘Start / Stop’ button several times while all the indicators (ABS/DTC, SRS, etc.) light up in the KOMBI;
c) using INPA select model, engine type (MSD80 for N43/53).
1. open INPA adaptation menu, 2nd group: ../F8/F2
a) delete the adaptations (status: ignition on; engine off), pressing Shift+F9;
b) switch off the ignition, remove the key from the slot.
2. Insert the key, turn on the ignition, open Rough run menu ../F5/F7
Learnbit of flywheel adaptations has to be uncolored (white). If learnbit of adaptations is colored, repeat point 1.
If the learnbit of flywheel adaptations is uncolored (white):
a) turn on the engine;
Attention: the car may run unevenly! If EML (check engine) symbol appears on KOMBI and increased/incorrect idle is observed:
- turn off the engine; turn on the ignition;
- slowly press and release the accelerator pedal three times;
- start the engine;
b) accelerate till 100 .. 110km/h on even road;
c) switch the 4th gear (for automatic transmission – in manual mode);
d) release the accelerator pedal, brake with the engine (don’t press brake pedal);
After 5 .. 10 seconds learnbit of flywheel adaptations has to be colored in black. If learnbit stays uncolored, repeat from point b.
e) stop the car, switch off the ignition, take off the key, disconnect the diagnostic cable;
f) wait, till the lighting of the start/stop button turns off.
3. start the engine, connect INPA
Attention: the car may run unevenly! If EML (check engine) symbol appears on KOMBI and increased/incorrect idle is observed:
- turn off the engine; turn on the ignition;
- slowly press and release the accelerator pedal three times;
- start the engine;
a) open INPA fuel mixture menu ../F5/F6;
b) after a little while the MSD80 has to start to warm up the wide-band probes, PWM of them has to increase to 30 .. 60%;
c) allow the engine to run idle for 5 minutes;
d) perform the driving session with even speed 60 .. 90km/h; 5 .. 10min;
e) repeat points c & d for several times;
f) stop the car, switch off the ignition, take off the key, disconnect the diagnostics cable;
g) wait, till the lighting of start/stop button turns off.
4. start the engine, connect INPA
a) open INPA fuel mixture menu ../F5/F6;
b) after a little while the MSD80 has to start to warm up the control probes, PWM of them has to increase to 30 .. 60%;
c) allow the engine to run idle for 5 minutes;
d) perform the driving session with even speed 60 .. 90km/h; 5 .. 10min;
e) repeat points c & d for several times.
Recheck error memory of DME, clear if necessary.
5. Next few times, when starting the cold engine:
a) allow the engine to run idle at least for 5 minutes;
b) drive with longer driving sessions with even RPM and torque when possible.
With this, the creating of initial adaptations can be considered as complete.
Note: when adaptations are cleared, following error messages* can appear immediately:
- error messages relating DSC. Solution: drive 10 .. 15 min, switch off/on ignition;
- error messages relating throttle. Solution: turn on ignition, press and release accelerator pedal 3 times, then start engine.
During adaptation process (after old adaptations have been cleared) some error messages* can appear:
- error messages relating fuel trim (bank and/or cylinders individually);
- insufficient performance of CO catalytic converters;
- Lambda probes (trim and/or signal);
- uneven run (Stratified charge and/or Homogeneous injection).
*these error messages in the exact situation do not indicate any problems with the engine performance.
After new adaptations are completed (after 5 .. 8 driving sessions for cold/warm engine, at least 200 .. 300 km), check the new adaptations and clear error message memory using INPA or ISTA D/+, if necessary.
Troubleshooting
1. How to comply with ‘Ignition ON’? – my car does not have an ignition key, it is equipped with the Start / Stop button.
To activate ‘Ignition ON’ mode:
- insert the key into the slot;
- do not press any pedal (no clutch, no brake pedal);
- press the ‘Start / Stop’ button several times while all the indicators (ABS/DTC, SRS, etc.) light up in the KOMBI.
2. Communication with INPA breaks regularly. Cause: Incorrect latency setting.
Solution:
- Connect OBD/USB cable
- Open: Control panel / Device manager
- Select: Ports (LPT and COM)
- Select: USB serial Port (COM X)
- Enter sub-menu: Port settings / Advanced
- Set Latency time to: 1 msec*
- Press OK, confirm changes
*(default value: 16 msec)
Also:
a) close all realtime applications (Messenger, Skype, etc.);
b) disable Internet connection (both LAN and WiFi options);
c) temporarily stop all service procedures (Windows upgrade, HDD check-up, etc).
Re-adaptation of the engine using ISTA D/+
- Start new session in ISTA D/+, perform the identification of vehicle and a test:
2. open menu Vehicle management:
3. open menu Service function:
4. open sub-menu Power train, press Start search:
5. open sub-menu Engine Electronics:
6. open sub-menu Adjustment functions:
7. Select Delete adaptations/variants
8. Select Delete engine adaptation value, press Display
9. Select Reset adaptation values and versions (encoding)
Follow instructions on the screen.
Important!
Follow the instructions very carefully! If deleting of adaptations was successful, you will see notice “Adaptation values and taught versions were reset”. If ISTA D/+ does not displays notice “Adaptation values and taught versions were reset” after the attempt to delete the adaptations, repeat the procedure once again.
10. Adaptation of the flywheel
a) turn on the engine;
Attention: the car may run unevenly! If EML (check engine) symbol appears on KOMBI and increased/incorrect idle is observed:
- turn off the engine; turn on the ignition;
- slowly press and release the accelerator pedal three times;
- start the engine;
b) accelerate till 100 .. 110km/h on even road;
c) switch the 4th gear (for automatic transmission – in manual mode);
d) release the accelerator pedal, brake with the engine (don’t press brake pedal) for 7 .. 10 seconds;
Repeat points b .. d three times;
e) stop the car, switch off the ignition, take off the key, disconnect the diagnostics cable;
f) wait, till the lighting of the start/stop button turns off.
11. Re-adaptation of the fuel mixture
a) turn on the engine;
Attention: the car may run unevenly! If EML (check engine) symbol appears on KOMBI and increased/incorrect idle is observed:
- turn off the engine; turn on the ignition;
- slowly press and release the accelerator pedal three times;
- start the engine;
b) allow the engine to run idle for 5 minutes;
c) perform the driving session with even speed 60 .. 90km/h; 5 .. 10min;
d) repeat points b .. c for several times;
Connect INPA, recheck error memory of DME, clear if necessary.
12. Next few times, when starting the cold engine:
a) allow the engine to run idle at least for 5 minutes;
b) drive with longer driving sessions with even RPM and torque when possible.
With this, the creating of initial adaptations can be considered as complete.
Note: when adaptations are cleared, following error messages* can appear immediately:
- error messages relating to DSC. Solution: drive 10 .. 15 min, switch off/on ignition;
- error messages relating throttle. Solution: turn on ignition, press and release the accelerator pedal 3 times, then start the engine.
During the adaptation process (after old adaptations have been cleared) some error messages* can appear:
- error messages relating fuel trim (bank and/or cylinders individually);
- insufficient performance of CO catalytic converters;
- Lambda probes (trim and/or signal);
- uneven run (Stratified charge and/or Homogeneous injection).
*these error messages in the exact situation do not indicate any problems with the engine performance.
After new adaptations are completed (after 5 .. 8 driving sessions for cold/warm engine, at least 200 .. 300 km), check the new adaptations and clear error message memory using INPA or ISTA D/+, if necessary.
Troubleshooting
1. When starting a session with ISTA D/+, basic data of the car does not appear on the computer screen, they must be entered manually. Menus relating NOx sensor and NOx converter are not accessible.
The reason: communication problems between ISTA D/+ and the car. Typical problems with OBD / USB host or ICOM IP address and port settings. Contact the interface vendors to resolve the issue. If communication between the car and ISTA D/+ is established, the car’s basic data will be read from the car.
2. After confirmation of deleting the adaptations (by pressing ‘Continue’ after the warning ‘Adaptation values will now be reset’), the message ‘Could NOT reset adaptation values’ appears.
The reason: the condition ‘Ignition ON’ is not met, see p.3
3. How to comply with ‘Ignition ON’? – my car does not have an ignition key, it is equipped with the Start / Stop button.
To activate ‘Ignition ON’ mode:
- insert the key into the slot;
- do not press any pedal (no clutch, no brake pedal);
- press the ‘Start / Stop’ button several times while all the indicators (ABS/DTC, SRS, etc.) light up in the KOMBI.
4. After confirmation of deleting the adaptations (by pressing ‘Continue’ after the warning ‘Adaptation values will now be reset’), the message ‘Switch off Terminal 15 and terminal R’ appears.
Action required:
- switch off the ignition;
- remove the key from the slot;
- wait for further instructions.
