DTC C1275
PCM Requested ETS to Be Disabled

The PCM monitors various parameters and will not allow traction control operation if any parameter falls outside a specified range.
Conditions for Setting the DTC
The PCM diagnoses a condition preventing the engine control portion of the traction control function and sends a serial data message to the EBCM indicating that torque reduction is not allowed. The PCM will typically set a DTC and the EBCM will set this DTC.
Diagnostic Aids
This DTC is for information only. As an aid to the technician, this DTC indicates that there are no problems in the ABS/TCS system.

My 2007 isuzu i290 engine light keeps coming on. I already changed spark plugs and cleaned carburator


The check engine light comes on when your vehicle has a problem with the OBD 2 - onboard diagnostic's system . (emissions) When the light is on there are DTC'S - diagnostic trouble codes stored in the PCM - engine computer ! Changing the spark plug's may or may not do anything . There are a number of sensors that send signals to the PCM so PCM knows how much fuel to add to the engine . You need to take your vehicle to a qualified repair shop an have it check out .

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.

Diagnostic System Check - Engine Electrical
Test Description
The numbers below refer to the step numbers on the diagnostic table.
Lack of communication may be due to a partial malfunction of the class 2 serial data circuit or due to a total malfunction of the class 2 serial data circuit. The specified procedure will determine the particular condition.

How to reset engine light chevrolet traverse 2011


The check engine light arises when ECU finds any fault in the vehicle. Check for error code using On- Board Diagnostic system and then repair the codes.

Have a professional reset by on board diagnostic: You can tell any professional mechanic who have on board diagnostic system to reset the check engine light. The mechanic would not charge you with any penny.

If you do not want to try any of the above method then try hard resetting the check engine light; for hard resetting, follow the steps below:

1. Remove the battery terminals

2. Switch on the lights and press the horn for few minutes until last bit of electricity is drained.

3. When the horn stops working, you can now connect the battery again.

What is service engine light code 12 mean



READING CODES USING MIL (CHECK ENGINE) LAMP

Be advised that the MIL or CHECK ENGINE light can only perform a limited number of functions and it is a good idea to have the system checked with a scan tool to double check the circuit function.

  1. Within a period of 5 seconds, cycle the ignition key ON - OFF - ON - OFF - ON .
  2. Count the number of times the MIL (check engine lamp) on the instrument panel flashes on and off.

The number of flashes represents the trouble code. There is a short pause between the flashes representing the 1st and 2nd digits of the code. Longer pauses are used to separate individual 2-digit trouble codes.
An example of a flashed DTC is as follows:


Lamp flashes 4 times, pauses, then flashes 6 more times. This denotes a DTC number 46. Lamp flashes 5 times, pauses, then flashes 5 more times. This indicates a DTC number 55. DTC 55 will always be the last code to be displayed.

How can I check the codes without a diagnostic computer?


1
Locate the 16-pin data link connector. Connect the jump wire to terminals 4 and 9 of the connector. Turn the key to the "On" position without starting the engine.
2
Watch the "Check Engine" light. This light will begin to flash in specific patterns to indicate a 1- or 2-digit Diagnostic Trouble Code. The flashes will be long for the first digit, short for the second digit and blank if the digit is 0.
3
Record all the codes given. The "Check Engine" light will display the codes in sequence and then keep repeating them in order. Refer to your repair manual to check for the meaning of the codes.

1999 VW Bug Service engine Light


When you say water light comes on, do you mean coolant level, or coolant temp or ? Check coolant level and top off if needed. Bring the Beetle to a parts store, most offer free check of check eng. light. They will plug a hand held scan tool into the cars diagnostic port (usually located under the dash) and 'read' stored engine codes in the cars computer. They can tell you what the codes mean, and suggest what to do. If you have further questions, post them here along with the code numbers.
