15:19. Sensor of frequency of rotation of a wheel

 PERFORMANCE ORDER

  1. Lift the car and release the parking brake.
  2. Disconnect the socket from the HECU block.

Make sure that released a double clamp of the socket and connected the measuring probe to the socket from a plait of wires.

  1. Connect the voltmeter or an oscillograph to contacts of the socket and measure tension developed by the sensor at rotation of a wheel.

Contacts of the socket

1 and 2: forward left sensor
19 and 20: forward right sensor

5 and 6: back left sensor
22 and 23: back right sensor

Output tension at measurement by an oscillograph: 150 mV

Removal

Forward sensor of frequency of rotation of a wheel

 PERFORMANCE ORDER

  1. Turn out a bolt of fastening of the forward sensor of frequency of rotation of a wheel.
  1. Disconnect the socket and remove the forward sensor of frequency of rotation of a wheel.

Back sensor of frequency of rotation of a wheel

 PERFORMANCE ORDER

  1. Remove a pillow of back sitting.
  2. Remove an upholstery of a back rack.
  1. Remove a back wheel.
  1. Disconnect the socket and remove the back sensor of frequency of rotation of a wheel.

Check

 PERFORMANCE ORDER

  1. Between plugs of the socket measure resistance of the sensor of frequency of rotation of a wheel.

Resistance:

Forward sensor: 1275–1495 Ohms
Back sensor: 1275–1495 Ohms

  1. Connect the voltmeter to sensor socket plugs, measure tension developed by the sensor at rotation of a wheel.

Switch the voltmeter for measurement of alternating voltage.
