Hello Friends!!!!

I have gotten this error and I was hoping someone in the know might share advise with me.
"pwm signal failure from engine ecu"
From what I undersand, the SLABS ecu sends a signal to the engine ECU and the two determine together with various sensors what sort of road the truck is on.

In these kinda situations, what is usually the issue?

Thanks in advance

Hi, if you retrieved this code from the SLABS with some generic OBDII tool forget about it, if it's the message shown when you want to scan the engine ECU it's about lack of communication between the scanner and the engine ECU

btw what's the problem other than this code...describe better the whole thing if you want proper help
