You can check with Bro Nik on the level of SC Juru's mechanic experience with Scan 100, so don't too relying on their recommendation. Why don't you give a call to Stanley or Teng to see a 2nd opinion on MDP setting?

Like Bro KTLee suggested, can bring your Rex to the Taiping workshop to check out, better to deal the problem at the source rather than being in merry-go-round.

sc juru, ex sc mechanic... all ask me to change TCU , if not okay need to change gearbox... lastly Teng found the socket issue

I have discussed with 9885, we will arrange a visit to Taiping when my scanner is arriving so we can check any others issue on our rex.
we will post the date here again...

thanks bro.

can the scanner do actuator test....leak test?

Tg Bro car4ktlee As talk 2 u the 3 sc recomments 1) Kulim sc insist injectors problem .
2) Ssangyong Juru sc say MDP reading can go up mean injector ok .
3) Juru sc say i drive too slow must tekam kuat kuat so that MDP and
pressure can go up. He prefer at midnight go up highway drive at
170km/hr .Crazy i seldom drive above 120km/hr anyway i ask my son
to try few days while waiting 4 your scanner to arrive and meet at
Taiping.

Overhere maybe we can discuss a bit to understand more . 2 times jam scanner show injector balancing fault. What does this mean ? injector jam inside or no diesel spread or calibration problem . First time service in Taiping dont hv power loss problem but i dont know MDP count bcos Kulim sc bosch cannot show MDP reading so no data provided. Second time after service Kulim sc test drive with loss power scanner show zero errors nothing he can do anymore So i drive the car from Kulim to Juru to do G scan no errors also except MDP read 1 after 2 days driving i drive to Ssangyong juru to do scan 100 scanning no error found except MDP read 3. Drive 4 5days not much improve so last sunday get juru sc to test my car after driving he say we drive too slow must tekam kuat kuat.
Ok interesting here i do not know how they service injector need to wait until i visit Taiping to learn more. Just 4 knowledge hope bro lee done mine correct me if i am wrong.
1) After sevice how do we done the injectors are per manufacturing spec ?
2) Do we hv procedure to check after fix the injectors on car and test drive what is call normal or adnormal ?
3) What r the parameters we need sc to check or service b4 test drive or after test drive ? As what bro neonlee propose Rail pressure/ Maf/Map / ECU clean /EGR valve /Turbo wast gate.
4) Like my case check light up during driving stop the car, restart the engine, engine start with shaking and die off few secs.What type of injectors problem is it ? When this happen did your relative hv any method to make car move while outstation ? eg take out the injector knock it few times and put it back ha...... sound crazy . Stop here need to go 4 meeting again bye bye

Hi bro , You might encounter "injector balancing fault " after service injector , it is because the injected volume varies from the requested ,probally wrong C21 , after a period MDP will take place to override the varience and Compensate it , i had encountered this issue before , after speed like crazy @ highway , the error gone...smile.gif

Hi bro,
i hav discussed with Taiping sc yesterday about C2I issue. Our Rex is talking abt C2I of 16-digit code and market is launch with C3I of 20-digit code since 2010. This is even complicated but hav better fc control. Thru the discussion, we knowing that the 16-code is combination of 8 characteristic where obtain automatically by special machine. As we may know, the code can be 11, 99, AA, BB, CC, DD, EE, FF, From this combination, we understand that the max is 'FF' where representing '255'. So, we yet to find out this coding is base on what as reference point and how it optimise our rex FC/performance.

I check back our Rexton Manual taking about injector yesterday. I found interesting info where the manual explain injector function and why C2i and ECU control are important to our rex. Probably, 9885 has experience the extremly negative situation where coding and ECU is out of communication and detected by sensors. Finally, multiple fault may seeing on/off depend on ECU checking and driving behaviour. We see this complicated because we have advance ECU, if we have old model of diesel engine where no ECU/branch of diagnostic sensors, we see 'no problem' where the car is still move on the road perfectly. so, we may not detect any fault but high FC. This can be justified.. smile_wink.gif

Bro Neonlee advice can be true because our ECU is learning/adjusting the coding while we driving. Our ECU is inteligent enough to learn our rex speed from slow to fast and adjust the entering code. (bear in mind where the rail pressure is from 200bar to 1600bar) May be we need Neonlee advice further study at ECU to understand where 16-digit store and does our ECU modify the coding when rex is running for certain period. As we know, the coding is 'expired' after sometime due to wear & tear of injector. If we think out of box, if our rex does using '1 Malaysia' or default, do we having similar jerking as our bro 9885?? if no, why and what is the reason behind?

Anyway, Taiping sc has chit chat abt this with Bro Teerex, and they also felt that coding can be the best way to diagnostic this issue. I think we can try this out because this is software entering only no parts change. But, way of getting correct coding may be difficult and we may hav to try in error otherwise we hav to send to KL for regenerating code thru machine. I think bro Wilson has mentioned this before.

FYI good news to bro9885, Taiping sc has commit to check and test to diagnos the main reason. He will giv free consultant and workshop test as long as you are free to drop by because he also would like to understand how and why Kulim SC is insist on injector issue.

let me know if you have any doubt.

cheers,
Jayce Lee

Every Delphi Common Rail injector is allocated its own specific 'C21' code. This 16-digit code relates to the precise performance
of each individual injector and the vehicle will only perform to a high standard of the correct code is programmed to the vehicle ECU. Only Delphi Common Rail specialists have the test equipment and dedicated software required to generate this C21 code and then write it to the ECU.


Can pass the contact of the Injector Repair Specialist in Klang to check if their test machine could generate the code.

If the same injector are installed back to the same position, do not need to re-enter C21 code. Few bros is running on injector withouts its C21 code without problem as well, probably response lagging.

Here is an interesting read on Remanufacturing Process Issues of Fuel Injectors for Diesel Engines that explain the issues and process of manufacturing of injectors.

The correction of coding is a close loop process aka MDP learning, as current i'm able to do C2i coding and read MDP count but not MDP reset.
try unplug MAF and test the car , cause if MAF unpluged default value will be used.

Bro,
Just confirm with Bro Peter that we will meet at Taiping workshop on 14Apr (Sat) 9:30am.
Jalan Simpang Batu 2-1/2, 34000 Taiping

If you are from Pen, exit from Toll Taiping Utara. Immediate traffic light turn Right towards to Ipoh direction.
You may see JPJ, BHP station and Police station, you should come to a cross junction with traffic light. Turn Left to Jln Simpang at cross junction and you will see McD at Left. Follow the way and before T-junction traffic light, you shall see Toyota, Nissan, Hyundai, Ford workshop at Left. Immediately after Ford workshop you can see Leong San Deisel Pump service, drive-in and we will meeting here.

Call me if you have any doubt.
Cheers.
