Well since the lights are controlled by the OBD (on board diagnostics), you'll have to reset it. You may be able to do this by simply disconnecting the battery for a few hours. However, a lot of newer vehicles have electronically locked radios which require the manual to be able to be re-enabled.

I'd check out the radio before disconnecting the battery.

The only other ways are to physically disconnect the lights in the dash or get someone with an OBD reader to clear the codes.

SOURCE: the check air bag light stays on , and a service air bag alert at info center

Sounds like the sensor is tripped due to low pressure in the compressor you have to get the unit charged and the light will go off. Or take it to a auto parts store and have them put their diagnostic code reader on their and have them clear the codes this may fix it as well

Replacing brakes will not shut the abs light off. You have either a bad sensor or accumulated dirt on a sensor. There's a sensor for each wheel so you have to either pull a code or visually see which sensor is bad, craced, chiped, etc, then change. As for the CE light, go to auto zone and they'll hook it up and tell you why it's on. You have to use a scanner to find out.

SOURCE: air bag and abs lights staying on

If the Airbag light is on, it indicates that a electronic fault is stored in the memory for the airbag. You will need to have a diagnostic check done to pinpoint what the fault is, have it sorted out and only then can the fault be cleared so the light will go off. The ABS light also indicates a fault on the electronic side of the braking system. If the light comes on as you start the vehicle this indicates that there is an open circuit in the wiring or that the ABS control unit itself is faulty. If the light only comes on once the vehicle is in motion, this indicates that a wheel speed sender is incorrectly fitted or dirty and not sensing the ABS Rotor on one of the wheels. If a CV joint has been replaced, the joint may not have an ABS ring fitted on it.[front] At the rear the ABS pick up is fitted on the inside of the brake discs and must be fitted to the new disc when replacing discs.

The Automatic Transmission Diagnostic System Check is an organized approach to identify a problem created by an automatic transmission. The Diagnostic System Check - Engine Controls in Engine Controls - 4.2L or Diagnostic System Check - Engine Controls in Engine Controls - 4.8L, 5.3L and 6.0L is the diagnostic starting point for an automatic transmission complaint. The Diagnostic System Check - Engine Controls in Engine Controls - 4.2L or Diagnostic System Check - Engine Controls in Engine Controls - 4.8L, 5.3L and 6.0L directs you to the next logical step for diagnosing a transmission concern. Perform this check only if there is a driveability complaint or if you have been directed here from another service information section.
Follow the table to help reduce diagnostic time and help prevent unnecessary replacement of good parts.
  1. Install a scan tool.
  2. Important: Check for applicable service bulletins before proceeding with this test. Perform this test only if there is a driveability complaint or if you have been directed to this table from another section in the service information.
    Important: Do not turn the ignition OFF when performing this diagnostic procedure. Do not clear the DTCs unless instructed by this diagnostic procedure.
  3. Turn ON the ignition, with the engine OFF.

I have multiple codes instrument cluster codes: u1073, u1262, u1059, u1123, u1041; ABS/TCS codes: u1073, u1262, C1805, B2900;


Did you change any modules on the vehicle ?
B2900 VIN Mismatched ABS Module VERIFY that the module has the correct as-built data.
CHECK for correct powertrain control module (PCM) and ABS module configuration using the diagnostic tool. RECONFIGURE the component as necessary. FOLLOW the diagnostic tool directions for the ABS module configuration or REFER to Section 303-01A or Section 303-01B for the PCM. CLEAR the DTC. REPEAT the C1805 Mismatched PCM and/or ABS/TC Module ABS Module CHECK for correct PCM and ABS module configuration using the diagnostic tool. RECONFIGURE the component as necessary. FOLLOW the diagnostic tool directions for the ABS module configuration or REFER to Section 303-01A or Section 303-01B for the PCM. CLEAR the DTC. REPEAT the self-test. U1073 SCP (J1850) Invalid or Missing Data for Engine Coolant PCM REFER to Powertrain Control/Emissions Diagnosis (PC/ED) manual. U1262 SCP (J1850) Communication Bus Fault Network Fault REFER to Section 418-00 . Can a scan tool communicate with all the modules on the vehicle ?
  • The anti-lock brake system (ABS) module or stability assist module (if equipped) does not respond to the diagnostic tool
  • Circuit or connection in the standard corporate protocol (SCP) network.
  • ABS module.
  • Go To Pinpoint Test A .
U1123 Invalid or Missing Data For Odometer Instrument Cluster Go To Pinpoint Test G . U1059 SCP (J1850) Invalid or Missing Data for Transmission/Transaxle/PRNDL PCM REFER to Powertrain Control/Emissions Diagnosis (PC/ED) manual. U1041 SCP (J1850) Invalid Or Missing Data For Vehicle Speed Instrument Cluster REFER to Section 413-01 . U1041 SCP (J1850) Invalid Or Missing Data For Vehicle Speed Tire Pressure Monitoring System Module REFER to Section 204-04 . You need to take it to the dealer , not a transmission shop. Your vehicle could have a ground issue , could have power issue , could have a control module issue . It needs to be hooked up to the factory scan tool ! It is for sure it has a communication problem on the SCP data bus , do you know what serial data communication is ?
The vehicle has 3 module communication networks:
  • the standard corporate protocol (SCP) communications network
  • the international standards organization (ISO) 9141 communications network
  • the universal asynchronous receiver-transmitter (UART) based protocol (UBP) communications network
The diagnostic tool connects to all 3 networks through the data link connector (DLC). This makes diagnosis and testing of these systems easier by allowing one diagnostic tester to be able to diagnose and control any module on the 3 networks from one connector. The DLC can be found under the instrument panel between the steering column and the radio.
The SCP communications network will remain operational even with the severing of one of the bus wires. Communications will also continue if one of the bus wires is shorted to ground or voltage, or if some but not all termination resistors are lost. The SCP communications network allows inter-module communication.
The ISO 9141 communications network does not permit intermodule communication. When the diagnostic tool communicates to modules on the ISO 9141 communication network, the diagnostic tool must request all information, or initiate module commands.
The ISO 9141 communications network will not function if the wire is shorted to ground or battery voltage. Also, if one of the modules on the ISO 9141 communications network loses power or shorts internally, communications to that module will fail.
The UBP communications network will not function if the wire is shorted to ground or voltage. The UBP is different from the ISO communication network in that it allows intermodule communication.

ABS system will not communicate with my OBD II ABS scanner tool


You need a separate scan tool for that because they are on separate computers.

Abs warning light on


Just like your engine computer stores codes and turns on your check engine light, your ABS computer stores codes and turns on your ABS light. You can retrieve these codes with a scan tool, but it has to be one that can communicate with your ABS computer. The less expensive scan tools just will not do this, I would suggest taking it in to a shop and having the codes read, then you can decide if you want to fix the problem yourself or have a shop do the repairs. Chances are good that it would just be a wheel speed sensor gone bad, but you just don't know or know which one without having the computer scanned.

Abs light and esp light on on my 2001 mercedes benz 320


Hi,

It seems that there was a DC and the chat was Disconnected.



These lights are most often caused by a faulty brake light switch. However, to be sure, it would be best to have the ABS control module scanned using an MB-compatible scan tool that can communicate with more than just the engine control module. The scan tool will also be necessary to turn the light off, even after the repair is completed.



For information's sake, the brake switch is less than $25, and takes about a half hour labor to install.


Let me know, if needed further assistance.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!

ABS light stays on


have you had abs system checked with a scan tool?if you cannot communicate with abs module with a scanner,there is main power feed circuit that corrodes under fuse block underhood..also have seen corroded wires near abs module over top of transmission..if you have communication..you may have a speed sensor fault..if a front sensor,check wiring behind splash shields in fenderwells,if rear sensor fault,most likely sensor is defective..also check for water intrusion into rear wheel bearings by removing sensor from hub unit
