We have installed FMC125/150 devices on Howo Sinotruk trucks. We don’t have a technician familiar with Teltonika devices, so a local automotive electrician and I are trying to troubleshoot using online resources. These are Chinese heavy-duty Sinotruk models (2024), particularly those with chassis numbers LZZ5BLSF2RN268731 and LZZ5BUSH5RB091990
When we attempted to test the SECO feature by using an automated relay on the fuel pump wire, the fuel pump did not disconnect. It seems this is because these trucks use a mechanical fuel shut-off cylinder rather than an electronic fuel pump.I also noticed that these models are not listed in the FMC150 supported vehicles list, which suggests that the FMC125 likely has the same limitation.
Could anyone please confirm this? Are there other Teltonika devices that support Chinese Howo Sinotruk models, or is there an alternative solution?
Thank you in advance for your guidance.
