C1241 Magna Steer Circuit Malfunction
Hi there folks!
I just got a C1241 magna steer error code in my 1997 C5 while driving on the freeway.
The steering suddenly got a lot stickier as well.
Could this be due the leaking steering rack or is there something else I should be looking?
Could it be the ABS sensor in the front wheel?
Thanks!

Here are the diagnostics to review as a starting point.

As far as I know,, 97 & 98 EBTCMs contain the MAGNASTEER components. There is a dedicated relay inside the module mounted to the circuit board.
Im at work and can not use Sams DROP BOX to view the circuit.
Use the troubleshooting guide and figure out what is missing.

Ah,,,,, You have the schematic & the TROUBLESHOOTING Procedures. Can you use a METER?
You need to check:
The connector/pigtail on the steering rack, the connector (specifically the FEMALE PINS for damage/spread apart) and you can check voltage and ground at the harness from the EBTCM.
CHECK THE RESISTANCE OF THE COIL IN THE RACK!

Unfortunately, this is beyond my skill level. Just basic wrench work for me. However, this is useful info to have when I take it to the shop. Thanks!

C1241 Magna Steer Circut Malfunction
I have a 2002 ZO6. I have a C1241 code that comes back after I remove it. I took it to a local shop that said the EBCM needs to be repaired. ABS Fixer said a repaired EBCM would not fix code C1241. Is this true?

Go look at it and see if the wires are damaged and or the pins in the connector are in good shape.
You will more than likely be asked to take some voltage and resistance readings at that connector. BE PREPAIRED to do that. Get a meter and learn how to use it to get the raw data.

Brother,,,, You need to do a little SELF Diagnostics investigation... Start with the connector on the rack. Is it properly connected and in good shape??
