Hello all! I have a 2000 SL600 and the ABC suspension light came on the other day. I had the codes read with the STAR and these are the ones I got:

C1320 Damper valve FL Y51 (short circuit)
C1321 Damper valve FL Y51 (short circuit)
C1322 Damper valve FR Y52 (short circuit)
C1323 Damper valve FR Y52 (short circuit)
C1324 Damper valve RL Y53 (short circuit)
C1325 Damper valve RL Y53 (short circuit)


I followed the test steps recommended under Suspension Control (Automatic-Electronic): Testing and inspection 7.0-7.2, 8.0-8.2, 9.0-9.2, and got the correct voltage at the N51 connector and used a digital multimeter to check the ohms of all of the axle solenoid valves, and they are well within tolerance.

I have a hard time thinking that all three of these solenoids failed at the same time and at this time am thinking that the ABC module, or ABR module (part#018 545 95 32) is to blame.

Am I on track? Im hoping that someone with extensive knowledge with the STAR or this System can help? I have searched the forums in depth but have not found anything specific relating to my situation.

Thank you in advance!
