Re: [FIXED] P1352 FAULT
No problem, the relay boxes do fail, so shouldn't be too difficult to confirm once the other checks have been done.

Re: [FIXED] P1352 FAULT
After verification the first step, which is : "Check the continuity and insulation of the electrical harnesses between the pre-heat glow plugs and the pre-heat unit".
I have identified, when I put my black lead of the multimeter to the battery "-" and touch by the red lead the hole (pin relay sit place) of the bottom relay part (mother bottom connecter) which is supposed to be connected to the glow plug (according to the pins location). I read some value but after it immediately shows me OL, which is pointing to the open circuit if I understand correctly. I did it for the 4 glow plugs pins, but the result was the same. Seems, I need to investigate it more...

My problem was resolved. Maintain the information here, it could be useful for someone.Clark wrote: ↑02 May 2024, 18:22 After verification the first step, which is : "Check the continuity and insulation of the electrical harnesses between the pre-heat glow plugs and the pre-heat unit".

1. Found a damaged cable that goes to the glow plug, cylinder 2 (below the air filter, last chain connector). Potentially all of them can have a such problem.
2. The fuse box located right above the battery has a fuse called 'FL9' (which is responsible for the preheating chain). Discovered that it was not properly tightened.
3. Run the engine with an old relay. Clean errors. Leave the battery unplugged for 30 minutes.
4. Install the new preheating relay.
For now, I don't have a P1352 code anymore.
Thank you all!
