Behind me is my year 2006 model MITSUBISHI TRITON 3.2 litre ML L200 diesel truck. It has over
120,000 kilometres. Last night, I took the truck out. After driving for about 10 minutes, the engine
warning light came on. I had to go somewhere so I couldn't do anything about it. This morning
I'm going to use my G-SCAN2 to see what's wrong with the vehicle. So join me in this video as I
try & uncover what the problem is.
I'm in my car. I have the key in. I'll start the engine so that it can clear some of those lights. You will see that the engine warning light remains.
As you can see, I've got park brakes on. That's correct. My car door is open. Yes, that's correct. But
on the bottom-left, the engine-warning light remains on.
So I need to find out what the problem is.
I've connected my G-SCAN2 scanner
cable to the OBD2 socket under the car console. I've turned off the engine, & left the key in
accessories power on. With the OBD2 cable connected to the car ECU, I'm turning on my G-SCAN2.
Go to . Press for MITSUBISHI .
It's identified my vehicle. We'll press to continue.
Do a full .
Once I press , this will take a while as it scans the vehicle ECU.
You see for this subsystem, it has detected 3 DTC trouble codes.
So it's gone through the ABS/ASC/ASTC/WSS subsystems. It's okay. SRS-Airbag is okay .
ETACS has 4 DTC trouble codes.
It's finished the diagnosis. So let's get more details on these 3 DTC codes. Press .
press .
Number 1 cylinder misfire detected. ASC CAN timeout. T/M CAN timeout. I have to
take now these DTC codes, & do some research on what the errors are. I'll go back upwards,
& find out what these other errors are. The ETACS set of 4 DTC errors.
So take note of what these errors are as well, & do some research.
I changed my mind about what to do with these DTC codes.
I think what I'll do is I'll erase these codes,
& see if they come back. And because I've taken note of what the codes are, I can do
some research on them anyway. And if after I erase them, they don't come back... then it's just an
intermittent electrical contact issue. So I will erase each of these codes. To do that, push
"Are you sure you want to erase all DTCs?" And I say .
Erase the next one.
Doesn't seem to go away. Wonder why?
Go back up & see if it sees the DTCs again.
Hmmh, doesn't want to erase it,
although it says the erasure succeeded. I turned off the engine ignition & accessory power
completely. Then I restarted the engine, & turned the engine on. Then turned the engine
off completely, & left it in accessory power on. Then I restarted the G-SCAN2 connection
to the ECU. This time it does not detect the diesel subsystem DTCs anymore. But it still
detects the ETACS DTC errors. So I will have to investigate what those 4 ETACS errors are.
If I try & erase them,
they probably still will not go away.
Oh! No, they've erased them. Okay that's good. Let me go back up.
That's interesting it's still there.
Let's reconnect & see if it sees the 4 DTC errors.
No, it has erased those errors. That's good. Okay.
So it must be that I do have to turn on the engine to let
all the subsystems calibrate, & then turn the engine off. And leave the accessory power on.
And then re-establish connection of the G-SCAN2 to the ECU. After I use my G-SCAN2 to clear the
codes, the dashboard does not have any engine warning light anymore. If I turn the engine on,
we'll wait a while to see if the engine warning light comes on.
Still no engine warning light.
So that's good. I'm pleased to tell you that nine days & 56 kilometres after my car first showed an engine warning light; & the next day I erased those DTC error codes.
The engine warning light has not returned. So it does seem that the engine warning light could
have been due to intermittent communications faults. So that is good news. I found it useful to have a
full vehicle programming tool like this the G-SCAN2 which works for just about any vehicle on the
market. Different brands I've used it on a TOYOTA HIACE van. I've used it on a FORD RANGER diesel.
I've used it on this. I've used it on VOLKSWAGEN GOLF TDI 1.9 litre diesel. It's fantastic! Do hit the
