VZ no acceleration, safety mode

[scvs6]

Hey guys,

Just thought I would post this up just in case anyone is interested or is having this problem.

Within the last 2 weeks, 3x VZ Commodores (Alloytec V6) have came into my workplace on a tow truck. And believe it or not, they all had exactly the same problem.

A warning message is displayed on the LCD screen "safety mode" (or similar). The engine wont rev up when the accelerator is depressed.

Anyway, the problem with the 3 cars was the plug on the bottom of the throttle body was broken (it would still plug in but kept sliding back off), and this happened right after the 120,000km service (when the spark plugs were changed), so when the inlet manifold was removed, the clip on the plug was damaged while unplugging it.

So in the end, we ended up buying the plugs from a wreckers (cut off a wiring loom) and re-wired another plug onto it, properly.

Just wanted to share that with everyone because it isn't too often that something like this happens and if someone has the same problem, hopefully I just saved you alot of time and money.

Chances are its another mechanic ripping the plug out instead of removing it carefully. Though its good to know about.

Yeah the cars were serviced at another mechanic/workshop (not at Holden dealer), but I don't think all 3 cars were serviced at the same place. The clips that hold the plug in were broken, and one of them even had silastic on it (so they knew that it was broken and tried to 'fix' it).
