Default Error codes

My car of lately has just quit running. I am getting these error codes on the DIC:

28 TCS C1276 HC Delivered torque signal circuit malfunction
10 PCM P0606 HC control module internal performance
P1518 C Throttle actuator serial data circuit


Lately over the last couple of months the traction control has been acting up when I really romp on the gas. I mostly drive in Comp mode and it will switch to traction control on after I gas it hard and then tracion control off after I gas it hard again. The traction control/active handling just goes bonkers. The DIC has been displaying service traction control and active handling needs service.

Now the car went into reduced power mode and service ABS and service active handling and does not start at all.

My car has turbos and make 640 rwhp and 667 torque.

Anyboyd has any ideas where to start, thanks.

The PCM and TAC codes are causing the TC shutdown. The EBCM is telling you that it isn't getting the delivered torque signal from the PCM. Try clearing the codes and see if the PCM comes back. You may need a new PCM.

I just went through this myself.....Getting my 98 back tomorrow after new PCM...Sadly the new PCM would not take the file upload of my old dyno tune settings properly, so my tech had to re do the whole dyno thing too...

There is a LOT of information in this thread with help from some guys who REALLY know the stuff...Please take a look. You might have a bad PCM and you might have a bad ignition switch...Bill Curlee tells how to test!
