Cruise Control sending car into Limp Mode

[Gavel]

Howdy,

 

I purchased a cruise control module from Audio Express in 2014, who installed it, however now, whenever the accelerate pedal does anything while in cruise control it send the car into limp mode.  

Since Chris is no longer at audio express and doesnt accept messages, does anyone have any idea how to fix it? Or did i burn nearly $800 for temporary cruise control?

Have it checked for fault codes, not all fault codes will throw a MIL.

You might have blown the fuse of the cruise controler or a bad earth.

It happen to mine when the car was jump started once.

His cruise control is working so fuse is intact, the installation is interfering with inputs to his ECU or TCU hence why diagnostics should start with consult, then you have a starting point and NOT a guessing point

No.  Surely not!

Nissan put the consult port in for shits and giggles, we all know that.

Thanks Rusty, will take it to a shop when i get the chance to have them look at the codes, appreciate it.

The CC I have in mine basically splices into the throttle pedal sensor, so the CC just simulates the throttle input, if yours is the same, then I suspect either the CC unit is faulty, or the wiring harness used by the CC has bad connections.

Mine went into limp mode on hard right turns at one point and it turned out to be a bad crimp on the CC harness, I removed the connectors and soldered all the connectors and the problem never occurred again.
