Fault P0600- P0600 Can Time-Out - Signal Implausible

Recommended Posts

After putting 200 miles on the 996tt in a long daily routine, I came home to find my flash software ready for install. As soon as I finished loading the flash and started the car I get PSM/ABS warning messages. The idle is awful (was perfect), and the garage reaks of gasoline to the point where my eyes hurt while sitting in the car., It is running wayyy rich. Feeling dangerous (anxious), I took the car out to see if it boosted anyway. I only booster .4 bar.

Not 30 minutes earlier I was running .8 bar up to 120 mph on the interstate but as soon as the flash loaded, I was dead in the water. I didn't have any fault codes so I checked the usual suspects... cleaned the MAF, checked all the boost hoses (didnt remove bumper to check top of intercooler), removed battery for 30 minutes, checked battery charge -100%.

It is notable that at mid-day today, the car died at an intersection coming off a spirited acceleration into traffic. I have a 3" exhause with no cats on a tip and I am told this is semi-normal.

Tonight I let the car cool down and started it up again. After 10 minutes of idle, I finally got a CEL code P0600 CAN Time-out - Signal Implausible..

I have never heard of this from anyone here or either of the other sites.. any suggestions at all???

I reloaded the flash with no change at all.

P0600 236 CAN timeout Tiptronic - open circuit

Potential causes:

- Wiring harness

- Tiptronic control module not connected

- Tiptronic control module faulty

Thanks Loren,

What makes me nervous is that there was no fault prior to the flash. Also, why would tiptronic control module cause a bad idle?
