    Volvo FC2924C showing "Warning: Turn off engine. Engine error."

    100%. I've spent my fair share of time trawling forums for info on a specific problem, and so often just when it gets interesting, the thread goes dead.

    Volvo FC2924C showing "Warning: Turn off engine. Engine error."

    Thought I'd post a final follow-up: After replacing the injectors, the rail pressure stopped fluctuating wildly, but it still varied more than I expected. However, the fault did not reoccur, and the machine operated flawlessly, so I declared the problem solved and moved on. After about a...

    Volvo FC2924C showing "Warning: Turn off engine. Engine error."

    Six new genuine Bosch injectors later and the first test run was smooth as a baby's bum. Rail pressure does still vary, but less wildly, and not as extreme. Variation was between 350-600 bar at idle, which is above minimum spec of 300 bar. Incidentally, for future searchers: the rail...

    Volvo FC2924C showing "Warning: Turn off engine. Engine error."

    PRV is fine; not a drip came out. Injector return is about 150-200ml/min. Looks like now might be a good time to go buy a new set of injectors...

    Volvo FC2924C showing "Warning: Turn off engine. Engine error."

    Bloody hell, you guys are awesome. Last night, after we found the PSID96-01 code, we did a bit of fault finding. The engine wiring loom looks very tired. Broken backshells all over the place, melted spi-wrap, etc. The fuel rail pressure sensor loom has been previously modified (obviously a...

    Volvo FC2924C showing "Warning: Turn off engine. Engine error."

    There's a bunch of faults, but the only ones which are active are the cooling fan which I can ignore, and PSID96-01. Rail pressure and engine rpm are fluctuating a lot. Rail pressure varied wildly from 300 to 950 bar. Incidentally I can't dismiss the warning message no matter what I do. I...

    Good info thanks mate. I'll have a crack at service mode and see if I can get any further information from there.

    Volvo FC2924C showing "Warning: Turn off engine. Engine error."

    The only error code that shows up in the menu is a cooling fan failure which has apparently been there for years. The extra hydraulic cooling fan shat itself years ago, so 99% sure its that. The main hydraulically run cooling fan runs fine. That location under the radio is empty, but it may...

    Any idea where the diagnostic port is hiding? Thinking of dumping a couple of grand on a scan tool...

    Volvo FC2924C showing "Warning: Turn off engine. Engine error."

    The machine is a Volvo FC2924C, which I believe is just an EC240 plonked onto an EC290 undercarriage in the factory for forestry work. Maybe a bit hard to start, but seems to operate normally. Shortly after startup the main caution lights up and the whole screen is taken up by a message saying...
