Attention: when diagnosing the speed sensors, the brake system works as usual (ABS not working).
1. Make sure the battery voltage is (with the ignition off) corresponds to the nominal value.
- Rated voltage - 10-14 V
2. Check the ABS indicator.
A) Turn on the ignition.
b) Make sure the indicator lights up for three seconds. If the indicator does not come on, check the fuse, indicator lamp and wiring harness.
3. Turn off the ignition.
4. Short the Leads "ECUT" - "E" diagnostic socket.
5. Turn on the ignition.
Note: make sure that the test mode of the system is set (3 s after the ignition is switched on, the ABS indicator should flash at 1 s intervals).
6. Checking while driving,
A) Start the engine.
b) Drive the car at a speed of more than 7 km/h.
Note: when changing the speed, do not allow the wheels to slip.
7. Read trouble codes.
A) Stop the car. The ABS indicator will flash.
b) Determine the fault code by the number of flashes of the ABS indicator (see table "Fault codes for speed sensors and deceleration sensor").
Note:
- During normal operation, the indicator blinks at a frequency of 2 times per second.
- 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.
V) Switch off the ignition and remove the jumper from the terminals of the diagnostic connector.
