'98 EBCM Codes

Hi all, recently my TC and ABS lights came on, I reset the codes, went for a little drive and they were triggered again, parked then pulled the codes and they read as follows, C1225H, C1232HC, and C1233H.
What are my options?

Possibly a wiring issue (likely to be at) the left front wheel, but also possibly a dead EBCM (code C1233H). Start checking connectors and wires, especially the ones on top of the frame rail on the drivers side. Be sure the connectors are clean inside and making good contact. Check wires for damage to the insulation and R/R as needed.

What are the chances of it being a dead ebcm? I’m wanting to know if I should get myself ready to spend the 2k on a used V module or live without the abs/tc.
Has anyone had personal experience living without the ebcm?

Both the TC system and thew ABS braking system uses the dara from your wheel speed sensors---The TC system uses the data to prevent your rear wheels from spinning on a hard launch The ABS system uses the data to prevent your wheels from skidding on a hard stop-- Most all of these related codes come from fouled wheel speed sensors from rain water or faulty wheel speed sensors--Anyone with a good diagnostic tool can tell you exactly which corner is acting up-- there can be other reasons for these codes but those are mostly associated with heavily modded cars Either a high stall converter or at least 100 added RWHP which with tuning can be eliminated

Fact is, I tuned tc out of my last car even though everything worked fine (common on a modded car). I don't recall abs ever engaging on mine in 6 years, so how important is that? Idk, I guess you could say I lived without both and never knew it.

Have you ever engaged abs and needed it? Have you ever engaged tc and wanted it?

Thank you guys for all of the information, I’m going to start with the wheel sensors and work my way through. If the issue is the EBCM itself not working I guess I’ll live without.
