    Thanks Dennis for your response. Lexus cleared these codes and told me to keep driving the car. I'm assuming that if I get the car scanned again it will probably come up with new codes relating to the engine problem??

These are not engine codes, they are body control system codes.

Got a 1997 Chevy Suburban 5.7 liter 4 wheel drive and the check engine light is steadily on. I not too long ago changed the spark plugs and just changed the EGR VALVE. As I drive now it's running rough....


What you do when the engine light comes on is to stop the vehicle ---check the oil level and let it cool down then check the coolant level at the radiator. The engine light is the message to you that the CPU has found sensors /servos that have gone outside set parameters and your course of action then is to prove that the engine is safe then run the fault codes to find the recorded faults and fix them . use the code reader to reset the CPU to ensure that the faults are fixed.

Abs and traction control lights do not shut off


Hello and welcome to JustAnswer, My name is XXXX *** I will be assisting you.... When the "Service Electronic Brake System" Message appears, its telling you that you have a fault in the ABS(Anti-Lock Brake System)...In order to properly diagnose your vehicle you will need to take it to a shop that has the capability to connect to the ABS Controller.. Once you get the codes, then I can tell you the diagnostics in order to repair your vehicle.. The repairs may range from a clockspring, speed sensor, ABS Module, SCCM, or just needs to be Updated...
Customer :

I did take it to a place and have them connect to the ABS sytem. I think this cost me around $100 with the assumption that it would go toward the repairs if needed. Nothing was done and the mechanic spoke to me personally saying that he thought the sensor could just have dirt or gunk on it but did not mention any codes coming up.
Brad :

Ok, if the light is on the system has codes in it... He may not have had the proper equipment to diagnose your vehicle... But if it says service electric brake system there is a code that is in it and in order to properly diagnose your vehicle, I will need that code... Your vehicle utilizes the newest type of communication which is Can-Bus...Alot of older vehicle scantools wont work with this type of system... You may need to take it to a dealership for them to pull the codes for you
Brad :

I have this case from Jeep, you cn read it and maybe you will understand why the codes are so important in diagnosting your vehicle.
Brad :
Case Number K56486465
Vehicle Issue ABS lamp on. Fault codes C1219 and U0126 logged in the ABS module.;The SCCM must never be replaced unless it has an internal fault related specifically to the SCCM module. If the following conditions are found: - fault codes C1219 and U0126 are logged in the ABS module - the SCCM has no internal faults (active or stored) - the ESP and ABS icons are on and - the Service Electric Brake System message appears The fix is relatively simple and does not require replacing an SCCM.
System or Component Will Not Clear,Will Not Reset,Will Not Turn Off;DTC / Error Message;ABS System,ABS Light / Anti-Lock Light;Yes - Continuously
Recommendation 1) Connect the Starscan tool to the diagnostic connector, power up the tool and set the ignition key to run. 2) Confirm C1219 and U0126 is stored or active in the ABS module. 3) Confirm no faults are active or stored in the SCCM. 4) Position the steering wheel so the tires are pointing straight ahead. 5) Use tool and go to the LID in the ABS or SCCM to observe SAS position. If greater than 360 degrees, you must re-center the SCCM/SAS. Fastest way to re-center the SCCM/SAS is: A) Remove knee blocker to access the steering column/intermediate shaft (I-shaft) knuckle bolt. B) Remove the bolt and slide the I-Shaft off the column shaft. C) While monitoring the SAS position with the tool, rotate the steering wheel at least 360 degrees so the angular position decreases towards 0 degrees (zero). Remember, if the tires are pointing straight ahead, we should be at 0 +/- 30 degrees, so we can reattach the I-shaft and tighten the bolt. D) Clear the faults in the ABS and turn the ignition switch off and then on twice to ensure the cluster warnings and respective faults do not reappear. If the fault reappears, refer to intermittent diagnostics. Please note that Service part numbers have been released to allow for the replacement of necessary components versus replacing the entire SCCM assembly.

What do codes: C1223, U0121, U0123, U0124, U0126 mean found after a diagnostic test in my 2004 Toyota Solara?


Same here. I stopped by Autozone and they gave me the following codes. P0020, U0126, U0124, U0123, U0073, C1223 and C1201. The only thing I did was splash some fuel the day before at a questionable gas station. Please help

2003 toyota abs light Codes C1203, C1223


C1223 - Left Rear Wheel Speed Sensor Input Signal is 0 C1203 - The procedure for this fault is to check for an open or short in the harness and connector between the Skid control ECU and ECM.If no faults are found with the wiring, then - the MIL stays off when ignition on but engine not running (Requires ECM replacing)
- the MIL comes on when ignition on but engine not running (requires ABS & traction actuator assembly)
These parts wont be cheap so i hope its a wiring fault smile.gif
If you take it to a Toyota dealership they should be able to do this for you pretty easily.
