Mercedes-Benz 190 E ABS diagnostics.

Sensor resistance and voltage measure.

Sensors should have following internal resistance:
Front: 1.1 to 2.3 kOhm
Rear: 0.6 to 1.6 kOhm

Alternating Current (AC) voltage on free spinning wheel should be no less than 100mV.

Diagnostics using built in control unit.

• Insert wire in diagnostic plug.
• Turn on ignition without starting engine.
• Connect wire to ground for 3 seconds.
• ABS and ASD lights should blink error code. Count number of blinks.
• To proceed to next code ground the wire for another 1-2 sec.
• Read codes until codes start to repeat.
• To erase outdated error codes connect wire to ground for 7-10 sec.
