Default What do these error codes mean????

I have a 92 and the ASR/ABS service light has been on. I did that trick with the paper clip!!!

What came up was....
First 1.
then C12
then 4.
then 9.
then H31
then 1.0

I assume that the 2 error codes are the C12 and H31 ..... anyone know what they mean???

Thanx for any help guys,
Gixxer Vette

H31 is history code for right rear wheel speed sensor don't put too much into the history part every time you pull codes by use of the CCM (A to G) every code other then the ones in the CCM (1.1) will read as a history only CCM codes can desplay as current C12 which just means the CCM is able to desplay codes don't worry about that one.
As for the wheel sensor in some cases this code can set because of metal filings building up on the sensor(it comes from the rotor and brake pads) which means that in some cases the removal and cleaning of the sensor may be all that may be needed. But if you do this and the code comes back check the wiring and if that look ok you will probably have to replace the sensor.
