Unknown R34 Error Code?

[OzanMakinaci]

The other day the TCS Off and SLIP lights came on while I was driving around (about 5 minutes after start). I pulled over and had a look under the bonnet nothing seemed obviously loose, turned the car off and started it again. This time the lights did not come on so I went for a drive and made sure ABS and TCS were still working right, they seemed to be OK.

Wasn't too fussed, but hopped on the forums after checking the self-diagnostic results stored in the ECU. Got error code 23 then reset the codes and checked again to make sure I got 55, and I did.

Problem is, I'm pretty certain it was 23 as I checked and double checked (since it repeats the error code). But I have gone through the service manual (english and japanese version) and there is no DTC 23 number. Only 21 (Ignition Circuit) and 33 (Heated Oxygen Sensor Circuit) are listed in the manuals.

Maybe, I saw incorrectly and it was three long flashes instead of two but I watched it like 5 times before turning it off.

Anyway, car is an '98 R34 GT-T, 25,000 KM and I have had the coil packs replaced about 3 months ago (all 6).

Anyone ever had just the TCS and SLIP lights come one before? What was it and did you get error code 23?

Cheers.
