 PERFORMANCE ORDER

  1. Disconnect an electrical wiring from the sensor of accelerations.
  2. Remove the sensor from the car and lay it on a flat surface.
  3. Measure resistance between plugs No. No. 2 and 51 of the sensor (see the illustration Check of the Block of the ABS Relay) — the required value makes 1400 — 1600 Ohms.
  1. Incline the sensor at an angle at least 23 ° — this time resistance between plugs No. No. 2 and 51 has to make 4700 — 5500 Ohms.
  2. Measure resistance between plugs No. No. 1 and 17 of the sensor — the required value makes 70 — 124 Ohms.
