Attention! The ABS warning light may remain on if the transfer case lever is in the LOW position (included center differential), as the system is shutting down.
1. To access fault codes, turn on the ignition (do not start the engine), bridge the conclusions E1 and Tc of the data channel connector and remove the plug from the sockets WA and WB (1 - jumper, 2 - plug). The transfer case lever must be in the 2WD position.
2. The numbers of the two-digit code are determined by the number of flashes of the control lamp, separated by a pause of 1.5 seconds (for example, code 34 - 3 flashes, a pause of 1.5 seconds and 4 flashes).
3. The next code appears 2.5 seconds after the first one. If the system is working, the lamp flashes at a frequency of 2 Hz.
4. Determine the nature of the failure according to the table.
5. After reading, erase the codes by pressing the pedal at least 8 times in 3 seconds.
6. Remove the jumper and replace the plug.
7. Take the car to a car service.
