- Rated voltage - 10 - 14 V
2. Check the ABS and slip indicators.
A) Turn on the ignition.
b) Make sure the indicators light up for three seconds. If not, repair or replace (if necessary) fuse, indicator lamp and wiring harness.
3. Read the trouble code.
(With ABS indicator)
A) Short the leads "ECUT" And "E" diagnostic connector (see picture "Diagnostics").
b) Turn on the ignition.
V) In the event of a malfunction, after 4 seconds the indicator will flash. Count the number of flashes.
Note:
- The fault code consists of two digits, the first digit is determined by the initial series of flashes, then after a pause of 1.5 seconds, a second series of flashes follows, which corresponds to the second digit of the code.
- If there are two or more fault codes, the smallest code will be displayed first, and then the remaining codes in ascending order. There will be a 2.5 second pause between codes.

Diagnostics.
G) If there is no fault, the indicator will flash at 0.5 second intervals.
d) Remove the jumper from the diagnostic connector.
e) After troubleshooting, erase the codes stored in the memory of the electronic control unit.
Note: if you disconnect the battery, all fault codes stored in the memory of the electronic control unit will be erased.
and) Turn the ignition on and check that the ABS indicator comes on for three seconds and goes off.
(With a tester)
A) Switch off the ignition and connect the tester to the diagnostic socket.
b) Turn on the ignition and read the trouble codes using the instructions for the tester. Determine the malfunction according to the table "ABS system fault codes".
Note: When troubleshooting, use the appropriate wiring diagrams.
V) Clear codes after troubleshooting.
