Have a 2004 gmc yukon getting codes c0040, c0550,c0455,c0296 in the abs computer. Trac and abs light on as well as suspension control.


C0040 - Right Front Wheel Speed Circuit Malfunction
C0550 - ECU Malfunction - internal write / checksum malfunction
C0455 - Either:
  • A bent terminal or poor connection at the SWPS may be one possible cause; or
  • The vehicle stability enhancement system (VSES) electronic brake control module (EBCM) calibration may be the other possible cause.
C0296 - Transfer Case Delivered Torque for Stability Control System Circuit

code p1750 refers to AT-hydraulic system mechanical malfunction====causes --wiring---shift solenoids--ECM---transmission mechanical fault. Have a pressure test done to determine if there is a mechanical failure in the transmission.

P1750 code


P1750 Electronic gear selector module. Low control unit supply voltage too low.


Clear this fault first, as gear position sensor is not saying transmission is in P or N in order for engine to start. Check voltage at battery. Should be 12.65 if fully charged.

Low voltage causes false codes too and if too many set they will need clearing. Spilling tea coffee or soda down the shift gate can cause similar problems. Also the wiring to the transmission can become oil soaked and not pass full voltage to shift module at the connector.
It is also possible this code has nothing to do with a no start and you have another componet failure. .

I have a 05 neon that wont shift out of second gear. When I first crank and drive runs fine when I break or stop check engine comes on. I can reset it then it will shift but after five minutes light comes...


It could be due to malfunction of brake paddle switch. you have to check brake paddle switch. if brake paddle switch get choked it can be happen due to Peddle switch gives signal to ECU as a vehicle stopped.

Park brake light flashes 10 times. For 1989 Chevy 1500 pickup. What does this mean?


This truck probably has Rear Wheel Anti-Lock (RWAL) brakes. There is a small black module near master cylinder that is the brain for this system. There are ways to check for diagnostic trouble codes in this system. Once you have any codes set, diagnosis can be fairly simple. PROCEDURE:
Diagnostic Trouble Codes (DTC) 's can be displayed by jumping terminals "A" and "H" of the Data Link Connector and observing the flashing of the "BRAKE" warning light. This should only be done when the brake lamp is "ON".
The terminals must be jumped for about 20 seconds before the code will begin to flash. Count the number of short flashes starting from the long flash. Include the long flash as a count. Sometimes the first count sequence will be short. However, subsequent flashes will be accurate. If there is more than one failure, only the first recognized code will be retained and flashed.

NOTES:
DTC's 6, 9 and 10 will only turn the "BRAKE" lamp on while the fault exists. These are soft codes faults and can only be read with the Tech 1 scan tool.
Do not jump terminals "A" to "H" if the "BRAKE" lamp is not on. Jumping the terminals with the "BRAKE" lamp off will set a false DTC 9. This will turn the "BRAKE" lamp on and disable the antilock system.

    Brake indicator lamb


    My Chiltons manual for the toyota seinna 1998-2002 it says that with the lite always on means ecu malfunction and the action to take is ' ecu problem '. Sometimes these manuals leave a lot to be desired.

    there appears to be a speed sensor on every wheel with the abs actuator assembly(including ecu) is attached to the brake booster.

    the manual says. . . .The ABS computer(ECU) is mounted within the ABS actuator and is the ' brain' for the ABS system. The function of the computer is to accept and process information recieved from the wheel speed sensors to control the hydraulic line pressure, avoiding wheel lock up. The computer aslo constantly monitores the system, even under normal driving conditions, to find faults within the system.
    If a problem develops within the system, an "ABS" light will glow on the dashboard. A diagnostic cod will also be stored in the computer and, when retrieved, will indicate problem area or component.

    I hope this helps

    DTC P1750: Mechanical Problem in Hydraulic Control System of A/T Clutch Pressure Control Solenoid Valve Assemblies A and B, or Problem in Hydraulic Control System

    NOTE:
    • Record all freeze data and review General Troubleshooting Information before you troubleshoot.
    • Keep these replacement solenoid valves on hand:
    • A/T clutch pressure control solenoid valves A and B
    1. Check whether the OBD II scan tool indicates another code. Does the OBD II scan tool indicate another code? YES - Perform the troubleshooting flowchart for the indicated code(s). Recheck for code P1750 after troubleshooting. NO - Go to step 2.
    2. Turn the ignition switch OFF.
    3. Replace the A/T clutch pressure control solenoid valves A and B.
    4. Reset the PCM memory with the PGM Tester or by removing the BACK UP fuse in the passenger's underdash fuse/relay box for more than 10 seconds .
    5. Drive the vehicle for several minutes in 1st, 2nd, 3rd, 4th, and 5th gears in the position.
    6. Recheck for code P1750. Does the OBD II scan tool indicate code P1750? YES - Replace the transmission. NO - The problem has been corrected

    Ferrari 360 modena f1 speed restriction, safe mode


    This great car does not have speed limiter, as you said the limiter is starting because the ECU detects a problem and put the car in limp mode, starting the Rev limiter.

    The only way to know the problem is by connecting the car ECU to a code reader, and interpreting codes.

    If the car goes in limp mode when you press the brake pedal can be a brakes related problem or even a contact on the brake light wirings, check if the lights are are working.

    Ask your mechanic to scan the ECU, this will tell you what the problem is.
