SOURCE: what causes the malfunction indicator lamp to comes on honda accord 2001?what can i do to correct it?

It could be anything at all that is electrical or sensor-related in nature. Your car is an OBD2 car (for emissions), and it's a very strictly-controlled system. As a result, pretty much anything that fails will cause the light to come on and will store a code in the computer. Go to AutoZone and ask them to scan your computer for codes - they'll do it for free, where a dealer will hit you for up to an hour's labor. They'll tell you the fault codes, which will point you in the right direction for the fix. Get the codes that come out of the scan and post them as a reply here and we can go from there.

SOURCE: Malfunction indicator lamp

The Malfunction Indicator Lamp or MIL (Also called the check engine light or service engine soon light) comes on when the on board computer detects an issue with the operation of the engine or transmission.

The best thing to do is to take the vehicle to an auto parts store like Autozone and have them hook up their scan tool to the vehicle and read the code. They can read it, tell you what it is and also tell you what the code means.

If it is pointing to a faulty component or sensor and you replace or repair the component the the light will go off on its own after the computer sees that the malfunction is no longer present.

You can have the code cleared, but if whatever caused the light to come on in the first place is not addressed then it will just come back on eventually.

SOURCE: malfunction indicator lamp in my toyota corolla is on how i fix?

The check engine light also called the malfunction indicator comes only when the computer control unit (called the PCM) senses a fault in the electronic controls of the engine and/or the emission system, there are about 200 possible faults that turn the light on, to know what has developed a problem you must have the system tested, this is called an OBD2 fault code test, Kragen and Autozone parts stores do this testing for free.

Can leaky shocks on a 2006 Cadillac DTS cause the traction control light to come on


If the light is on there are DTC'S - diagnostic trouble code's stored in ABS - anti - lock brakes computer . Have codes checked first , something wrong with electrical part of antilock brakes , I know, what does ABS have to do with traction control ! traction control is a function of the ABS control module . Leaking shocks ? clarify , air shocks etc.... Before you start guessing , have it check for codes .
This vehicle is equipped with the TRW 440 V antilock braking system.
The vehicle is equipped with the following braking systems:
?€¢
Antilock Brake System (ABS)


?€¢
Engine Drag Control (EDC)


?€¢
Dynamic Rear Proportioning (DRP)


?€¢
Traction Control System (TCS)


?€¢
Vehicle Stability Enhancement System (VSES) (w/JL4)

The following components are involved in the operation of the above systems:
?€¢
Electronic brake control module (EBCM)--The EBCM controls the system functions and detects failures.


?€¢
Electronic brake control module (EBCM)--The EBCM controls the system functions and detects failures.


The EBCM contains the following components:


-
System relay--The system relay is energized when the ignition is ON and no ABS DTCs are present. It supplies battery positive voltage to the solenoid valves and pump motor.


-
Vent tube--The vent tube, located in the EBCM connector, is an opening to the internal cavity of the EBCM. It allows ventilation of the EBCM internals.


?€¢
Brake pressure modulator valve (BPMV)--The BPMV contains the hydraulic valves and pump motor that are controlled electrically by the EBCM. The BPMV uses a 4 circuit configuration with a diagonal split. The BPMV directs fluid from the reservoir of the master cylinder to the left front and right rear wheels and fluid from the other reservoir to the right front and left rear wheels. The diagonal circuits are hydraulically isolated so that a leak or malfunction in one circuit will allow continued braking ability on the other.


Important: There is a rubber isolator located under the BPMV and on the mounting studs. The rubber isolators protect the BPMV and the EBCM from vehicle vibrations.


?€¢
The BPMV contains the following components:


-
Pump motor


-
Inlet valves (one per wheel)


-
Outlet valves (one per wheel)


-
Master cylinder isolation valves (one per drive wheel)


-
Prime valves (one per drive wheel)


?€¢
Wheel speed sensors (WSS)--As the wheel spins, the wheel speed sensor produces an AC signal. The EBCM uses this AC signal to calculate wheel speed. The wheel speed sensors are replaceable only as part of the wheel hub and bearing assemblies.


?€¢
Traction control switch--The TCS is manually disabled or enabled using the traction control switch.


?€¢
Stoplamp switch--The EBCM uses the stoplamp switch as an indication that the brake pedal is applied.


?€¢
Lateral accelerometer sensor (w/JL4)--The EBCM uses the lateral accelerometer sensor as an indication of the lateral acceleration of the vehicle.


?€¢
Yaw rate sensor (w/JL4)--The EBCM uses the yaw rate sensor as an indication of the yaw rate of the vehicle.


?€¢
Steering wheel position sensor (SWPS) (w/JL4)--The EBCM uses the SWPS as an indication of the position and rotation of the steering wheel.


This systems are very complex , your best bet would be to take it to a qualified repair shop .

Can you help with multiple electrical issues??


This vehicle is equipped with the BOSCH 5.3 antilock braking system.
The vehicle is equipped with the following braking systems:
• Antilock Brake System (ABS)
• Dynamic Rear Proportioning (DRP)
• Traction Control System (ETS) (w/NW7)
• Traction Control System (TCS) (w/NW9)
• Vehicle stability enhancement system (VSES) You need to have vehicle checked for DTC'S diagnostic trouble codes , do you know what they are ? The traction control , ABS an stability control are all a function of the electronic brake control system .It also seams the power steering is controlled by the Antilock brake system.The Magnasteer® is controlled through the ABS module and varies the torque by adjusting the current flow through the actuator.
Your best place to start would be to have ABS module scanned for DTC'S . Codes would point you in right diagnostic direction .

How to diagnose an ABS problem


You need to find out what code is stored in the ABS control module, if the light is on there is a DTC an the system is disabled ! Don't know if auto part stores can pull ABS codes or not , You'll have to check it out . Personally I say take it to a ASE certified repair shop if you don't know anything about anti lock brakes !

Can you explain a scan code of c1218 and code c1243


C1218 - Pump Motor Circuit Shorted to Voltage or Motor Ground Open
C1243 - BPMV Pump Motor Stalled /These are codes relating to your ABS system(antilock braking). It looks as though you may have a ABS system pump that has burned out. Replace the pump, not the module.

DTC trouble code 28 TCS C 1214 HC


The C1214 error is related to the electronic brake traction control module (EBTCM) BPMV pump motor relay contact circuit open. Check the 40A ABS Maxifuse in the underhood electrical center. if blown change it, clear the DTC and if it blows again check for a short in the 1642 line or internal short in the BPMV.
When an ABS/TCS operation is required, the EBTCM activates the pump motor relay and battery power is provided to the pump motor. DTC errors are either H (history) or C (current) I usually clear the history and see if it sets again later.
