Chosen Solution
2015 Honda Civic; LX, 1.8L V-Tec SOHC 16V; Manual Tran — Check TPMS, Check Power Steering, Check Emission System, Check Hill Start Assist, Check (VMS?) - all came on at once when starting yesterday. Tires are fine, P/S is fine, the vehicle runs and drives normally (I’ve had it for three years). I suspect a fuse, module, or connection.
Hey, Rick. Check your battery voltage. I’ve seen low battery voltage trick these cars into limp mode and/or set many different codes at once. If your battery voltage is fine, post a list of exactly which codes were present (ex: P0300) and I’ll see if I can find anything. I agree with your suspicion that it’s a connection or some module on the CAN-Bus.
