Defect Code 16
Defect Code 16:
Explanation:
Accumulator charging valve malfunction
Possible cause:
Short or break on control wire to plunger hydraulic unit
Short or break on B+ supply wire from ABS hydraulic unit to plunger hydraulic unit
Solenoid valve defective
Troubleshooting:
Switch off ignition and detach control unit connector.
Measure resistance at the control unit connector (X11) Pin 33/23;
Nominal value: 3.3 ... 4.3 Ohm
Measure inductance at the control unit connector (X11) Pin 33/23;
Nominal value: Approx. 20 mH
If necessary, remove plunger hydraulic unit, ensure plug connections is firmly fitted and check for corrosion, measure internal resistance of the solenoid valve directly at the plunger hydraulic unit.
Replace ABS/ASC+T control unit If no defect can be found on the wiring harness side.
