2013 canter 3c13 limp mode FIXED

Given the multitude of errors you are getting, if it was my truck I'd be making a trip to a Fuso dealer.
As I mentioned previously... there is only so much you can do on a computerised vehicle if you don't have access to the diagnostic tools. That sucks, but sadly it is the reality.

I local auto electrician said to phone him on Wednesday & hopefully he'll be able to come at the weekend , he has star diagnostics .
Failing that I'll have to get a breakdown truck to take it to mercedes .

 

[SkiFreak]

I don't know what the star diagnostics can do.
I am assuming that it can only read what is output from the ECU. It probably cannot test the actual function of the ECU, to make sure it is not faulty.
Not a common thing for an ECU to fail, but at the end of the day... it's just a computer.

I'm not sure , I know you need it for mercedes & mitsubishi .

Interested to hear what the auto electrician has to say.

Is the truck really in a derate state or is there just a loss of power?

When I first saw one in derate mode there was a very loud alarm going off in the cab and the top speed was limited to 5 mph. The vehicle power was reduced in stages over time.

If an alarm is sounding, try performing a manual DPF regeneration using the switch on the dash. The vehicle must be at operating temperature, A/C off and the parking brake set. When it fully completes the regen cycle and the RPMs return to idle, shut the engine off and physically remove the key, then wait 5 minutes before restarting the truck. It’s like doing a Cntrl, Alt, Delete on a computer.

At the moment the truck isn't starting , when it did run I did a parked regen roughly every 10 days - maybe after 100 odd miles when it had 4 notches on the gauge .
For the last 6 months it went in to limp mode more & more till it did it every day .
I ended up taking it to a garage & they changed some parts like the egr , air flow , dpf pressure sensor & it still went in to limp mode .
Then a month or two later one day it cut out 7 times when driving , I've not used the truck since & can't work .
A local garage who's to busy said unplug the injectors one at a time when it's running ( it started a few times in my drive but after a while it would stall & not restart )
Unplugging one of the coils made no difference to how the engine sounded , I ordered another injector yesterday .
It's a crew cab , I didn't unplug the injector nearest the back as it was awkward to get to , I presumed there's no way 2 would be knackered at the same time .
I had a code on the dash saying high resistance on one of the injectors so thought that must be it ....
Today I checked the codes again & there's a new code for another injector with high resistance ( I'm sure that's what the codes mean )
At this point I'm hoping it is 2 bad injectors & not a problem with the ECU .
If anyone can tell me where all the grounds are that would be great incase I've missed one .
I've checked the main ground at the chassis beside the battery , the one on the gearbox , about 8 that are together on the front of the chassis & a small one that's beside some sort of small round relay that 2 positive wires go on to not far from the oil filter on the body .
Any help is much appreciated thanks .

The codes I have at the moment are
Spn 651 fmi 5 &
Spn 652 fmi 5

Stuartm:

In my limited experience there are some of these "limp" conditions that will self correct once the problem as been eliminated. But there are others that can only be cleared by actual Fuso service centers/dealers. Is it possible for you to visit a Fuso Service Center? A local garage with potentially useful software diagnostics might not be the same.

Hi Howard , at the moment the truck won't drive .
Someone suggested to me I might have a broken canbus wire , seemingly if one canbus wire is broken it could effect everything .
In the past 6 months limp mode has gone on & off but started to get more & more often as time went by .
My exhaust brake also stopped working .

As I eluded to previously... fault finding computer controlled vehicles can be a real pain. I feel your frustration.
Simply throwing money and parts at it might work, if you're really lucky, but that's exactly what it would be; luck.
Sometimes you just have resign yourself to the fact that some things are beyond the skills of a mere mortal and are only solvable by a dealer and the resources they have at their disposal.

Having said that... I have seen evidence that dealerships can also have problems identifying tricky problems sometimes.
In my experience, it often comes down to the technical know how of the person doing the diagnosis, not the fact that they have all of the high tech gear. Some technicians are very smart, others... not so much.

With any luck, the auto electrician you mentioned, that will having a look at your tuck, will be one of the smart ones.

I have a friend who did auto repair and was a great diagnostician. He rented himself out to dealers just to diagnose hard problems. I also worked at a Chevrolet dealer while in high school. If a difficult problem came in, it was known that it always went to X because his diagnostic skills exceeded everyone’s. He lived high on a different plane in the shop’s hierarchy.

Nothing will mess up a CRD more than putting gasoline in the tank.

How much faith do you have in your fuel source?

Theres definitely only diesel in the tank
