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.

My 2006 chev equinox was driving fine but then the check engine light came on...when I went to accelerate there was nothing the vehicle would not move...also the TCS light came on as well


TCS light is for electronic throttle control . This will set a DTC - diagnostic trouble code ! Your best bet is have it taken , towed to a qualified repair shop .

How do i reset my traction control


Is your trac light lit ? If so it has a problem an till it is fixed , you can't reset it. Need to have it checked for DTC'S - diagnostic trouble codes .
If the ABS control module detects a malfunction, it will disable TCS and will command the BCM to turn the TRAC LED Off. The driver can also disable TCS, if desired, by depressing the TRAC switch. When the driver depresses the TRAC switch, the ABS control module will disable TCS and will command the BCM to turn the TRAC LED Off.
DTC C0276 TCM Traction Control Not Allowed
DTC C0275 or C0276
The TCM sends a serial data message to the electronic brake control module (EBCM) indicating that torque reduction is temporarily not allowed.
DTC C0550
DTC C0896
The electronic brake control module (EBCM) is required to operate within a specified range of voltage to function properly. During antilock brake system (ABS) and traction control system (TCS) operation, there are current requirements that will cause the voltage to drop. Because of this, voltage is monitored out of ABS/TCS control to indicate a good charging system condition, and also during ABS/TCS control when voltage may drop significantly. The EBCM also monitors for high voltage conditions which could damage the EBCM.

My Honda Odyssey 1999 auto zone has been check the engine it came with a code of P1676 what it that mean?


Got DTC P1676 or TCS DTC
31? Replace the Ignition
Switch
NOTE: This article applies to '00-02 Accord V6s
and '99-02 Odysseys.
Got a vehicle in your shop with DTC P1676
(FPTDR signal line failure) or TCS DTC 31 (engine
retard command [PFINH] signal)? A bad ignition
switch (the electrical half) could be the culprit.
NOTE: On the HDS, you'll see TCS DTC 31 listed
as TCS DTC 31-2.
Inspect the ignition switch solder joints for any
signs of overheating. If you notice the solder joints
are melted, replace the ignition switch.

Howdo i enter diagnostic mode 1994 deville


TROUBLE CODE DISPLAY:
After entering On-Board Diagnostics, a segment check is automatically performed and then any trouble code stored in computer memory will be displayed. Codes may be stored for the Powertrain Control Module (PCM), Instrument Panel Cluster (IPC), Air Conditioning Programmer (ACP), Supplemental Inflatable Restraint (SIR), Traction Control System (TCS) or Road Sensing Suspension (RSS) systems.
Each trouble code consists of the system abbreviation: (E: Engine, PCM), (I: IPC), (A: ACP), (R: SIR), (T: TCS), (S: RSS), a three digit code identifier, and the letter C or H. All codes for each system are displayed together, in the order of their three digit number (lowest first). The final digit of the code, a "C" or "H" is used to indicate whether the code is Current or History. A "C" means the fault was still present the last time the diagnostic test was run, while "H" means the failure was not present the last time the code was tested for.
If no codes are present for a system, a "NO X CODE" message (with "X" being the system i.e. E, I, A, R, T or S) will be displayed. If the communication line to a component is not operating, a "NO X DATA" message will be displayed, indicating that the IPC could not communicate with that system.
SELECTING THE SYSTEM:
After trouble codes have been displayed, a specific vehicle system PCM, IPC, ACP, SIR, TCS, RSS may be selected for testing.
The first available system will be automatically displayed (i.e. PCM?). While selecting the system to test, any of the following actions may be taken:
  1. Depressing the "HI" button on the CCC will select the displayed system for testing.
  2. Depressing the "LO" button on the CCC will display the next available system selection. This allows the display to be stepped through all system choices. This list of systems can be repeated following the end of the system list.
  3. Depressing the "OFF" button the CCC will stop the system selection process and return the display to the beginning of the trouble code sequence.
SELECTING THE TEST TYPE:
Having selected a system, the first available test type will be displayed (i.e. PCM DATA?, PCM CLEAR CODES?). While selecting a specific test type, any of the following actions may be taken:
  1. Depressing the "HI" button on the CCC will select the displayed test type. At this point the first of several specific tests will appear.
  2. Depressing the "LO" button on the CCC will display the next available test type for the selected system. This allows the display to be stepped through all available test type choices. This list of test types can be repeated following the display of the last test type.
  3. Depressing the "OFF" button on the CCC will stop the test type selection process and return the display to the next available system selection.
CLEAR CODES
Selection of "CLEAR CODES?" test will result in the message "CODES CLEARED" being displayed along with the selected systems name. This message will appear for 3 seconds and then return to the next available test type.
EXITING DIAGNOSTIC MODE:
To get out of the diagnostic mode anytime during the test, depress the "AUTO" or "DEFOG" button, or turn the ignition switch "OFF." Trouble codes are not erased if this is done prior to selecting "CODES CLEARED."
ECC Trouble Code Descriptions:
  • DTC A010 - Outside Temperature Sensor Circuit
  • DTC A011 - High Side Temperature Sensor Circuit
  • DTC A012 - Low Side Temperature Sensor Circuit
  • DTC A013 - In-Car Temperature Sensor Circuit
  • DTC A015 - Sunload Sensor Circuit
  • DTC A037 - Loss of IPC Data
  • DTC A040 - Air Mix Valve (Door) Circuit Problem
  • DTC A047 - Low Refrigerant Charge
  • DTC A048 - Low Refrigerant Pressure
  • DTC A050 - HVAC - Coolant Temperature Too High

How can I check the computer for alarms in the past and how do I clear them so I can trouble shoot a problem? where do I get a list of the code? for a 1999 Cadillac deville. Thanks


HOW TO "ENTER" DIAGNOSTIC MODE OBDII

To enter diagnostic mode, proceed as follows:

1. Turn ignition "ON." Engine can be either OFF or RUNNING.

For cars equipped with the Digital Instrument Panel Display (Digital IPC):
2. Simultaneously press the "OFF and "WARMER" (red) buttons on climate control center (CCC) until all display segments (IPC and CCP) are illuminated

For cars equipped with the Analog Instrument Panel Display (Analog IPC):
3. Simultaneously press on the Climate Control Panel (CCP) the "OFF" and "PASS WARMER" (up arrow) buttons.

After the segment display test, the driver message center displays all set DTC, current and history, in the following order:

1. PCM DTC
2. IPC DTC
3. ACM DTC
4. SDM DTC
5. TCS DTC
6. PZM DTC
7. IRC DTC
8. RFA DTC
9. CCP DTC
10. MSM DTC
11. MMM DTC
12. PHN DTC

The RSS, CCP, MSM, MMM and PHN DTC appear only on vehicles equipped with these options. Press the FAN DOWN button in order to bypass the DTC display.

On the OBD II cars, the prefixes you'll see are: "IP" for the IPC instrument panel; "AC" for air conditioning module; "TC" for traction control; "RS" for the road suspension system; "SD" for the air bags; "PZ" for the body control module; "CC" for the cell phone; "RF" for the integrated radio system.



HOW TO "EXIT" DIAGNOSTIC MODE

To exit the diagnostic mode anytime during the test, depress the "ECON" or "DEFOG" button, or turn the ignition switch "OFF." .

You don't need a scan tool for these cars,as it is all built in.

Go to the following website for a list of trouble codes.

Two seperate problems. I would say you have a bad wheel sensor. A trip to a local big chain parts store will tell you. They will run a diagnostic and pull the code for free. Hope this helps...

Hard start


DTC - 15 Engine coolant temp sensor error (low temp indicated)
This is an Diagnostic Trouble code using the OB1 which simply means the check engine light blinking in series at certain intervals.But my thinking says that if you are having trouble wuth any sensor , the ECU or PCU computer will read all kinds of things in error. Try replacing the TCS temperature control sensor.Only 96 and up have a OB2 Diagnostic system
