Ok, purchased a 2003 CL55 with 80k from auction. Long story short spent 5k getting it running since it has been sitting since 2009. Car is pulling some chassis codes and the front right strut is sagging. Have already attempted to delete codes with scan tool but they come right back after restart. Here is the list of codes c1034, c1200, c1200-008, c1043 and p10430f. Also message center is showing malfunction bas, abs, esp and abc. I'll add pictures from scan tool. Any help would be great. Trying to self diginose and repair.

Figured this much. I purchased a donor 2002 cl500 parts car. Thinking about swapping out abs module and abc valve block and see what happens.

Have you looked up what those codes mean?

Do the brake lights work properly?

Yes, i have found the meaning to each code. The drivers brake light stays on from time to time. Goes away with a restart. Removed the tail lights and cleaned the boards and checked all connections. Found some surface rust and removed with light wire brush. Added electrical grease to all connections still having same issue.

Can I suggest that you post them, to save everyone else from having to look them up? People are much more likely to help if its obvious that you're doing what you can.

The significance of the brake lights is that the brake pedal switch is a signal to lots of other equipment. If the switch doesn't work right, lots of other things don't.

Nick is right about the brake light switch. A faulty one could certainly trigger your chassis codes. However, I have never seen any DTC code that is more than 5 characters. That power train code is interesting.

These codes can also be precipitated by under hood chassis wires that have grounded due to age and eaten by mice. Pull off the plastic engine cover and check around cam covers and near firewall. Have you installed a fresh battery and checked alternator?

Im sorry guys i had to step away and this car sat this entire time. Ive put 30 miles on the car today after deleting all codes and here are the active codes:
c1011 power supply a7/3 (traction system hydraulic unit)
c1043 fault in can compnent a1 (instrument cluster)
c1200 s9/1 (stop lamp switch)
c1034 fault in can comm with control unit n73 (eis control unit)

Suspension would sag on the front right and driver rear would sit high. After driving 1 mile car would sit perfect. Codes come right back right when you start the car and showing on the cluster malfunction bas, abs, esp and abc. Once again im sorry about the long delay in response but life got hectic and had to step away.

Bump. Any help would be great.

Do the brake lights work?


Does the transmission selector work normally?

Yes the brake lights work fine and so does the transmission selector.
