Any ABS codes? Did you check it with the jumper wire method or only the scan tool? This code you have is for the vehicle skid control system it's detecting a malfunction in the ABS system.

I check with scaner it said abs malfunction in ABS system, I want to know where the problem is sensor on wheel or pump.

place a jumper wire in the terminals as dictated in the attachment. Turn the key to the on position and monitor the flash pattern of the ABS light. There will be a lot of lights flashing just focus on the ABS light. Let me know what the two digit code numbers are that it displays.

Jumper wire code 94

Just to clarify you're saying that you inserted the jumper wire as specified turn the key on and the ABS light flashed nine times the slight pause then for flashes? If that's the case then with a jumper wire installed and the key in the on position depress the brake pedal eight times or more within five seconds let me know if the ABS light starts to flash normal and the code clears.

abs flash normal

Remove the jumper wire and drive the vehicle and see if all the warning light stay out and the code C1223 goes away. If it does this 94 code is a bus line communication fault and could have been intermittent in the ABS system. It's possible that it is now communicating and all of the lights are out now since you cleared that code.

Code did not clear
Expert:  Skyvisions replied 9 months ago.

Are you 100% certain it is a Code 94 and it did not clear? The ABS light flashed rapidly after the brake pedal push 8 times or more in 5 seconds.
