Checklist
Test step Test of demand value
1 Power supply,
low voltage condition 12V -1.7 V +2.5 V
2 ABS warning lamp on, after a couple of sec.
3 EBD warning lamp on, after a couple of sec.
4 Brake light switch
- not actuated 0 V
- actuated U Batt
5 Wheel speed sensor
(Line Fault)
- sensor monitoring Ri = 1,6 K Ohm +- 320 Ohm
by 25 degree C
6 Wheel speed sensor
- sensor signal minimum value:
120 mVpp by 2.75km/h
7 Toothed gear correct to specification
Front axle: 51 teeth

8 Diagnosis
- K line mΩ -> flow resistance
- Ground mΩ -> flow resistance
+ Power supply U Batt
9 Ground for pump motor mΩ -> flow resistance
and diff. are required
10 Ground for solenoid mΩ -> flow resistance
valve and ECU and diff. are required
11 Acceleration sensor (value by horizontal plane
and static position)
-Output voltage
(K27/28, pin 2 → pin 1) U = 2.500 V ±0,75 V
-Supplay voltage
