All Toyota vehicles with electronic fuel injection utilize the Toyota EFI or TCCS engine management system. This system incorporates many features to enhance performance, emissions, and drivability. One feature is the Self Diagnostic System. The self diagnostic system monitors engine operations and when a particular sensor or input varies out of specified operating parmeters, the "Check Engine" will be illuminated.
READING THE TROUBLE CODES
Reading the diagnostic trouble codes is very easy. You will need a paper clip or auto wire to short the check connectors of the diagnostic connector. The diagnostic connector comes in two types. The early system is located on the inner-left fender well and is a round, green connector, usually located near the air cleaner. Simply jump the two terminals in this connector with the ignition switch in the "ON" position and the engine off. Later models, '87 and newer use a multiple terminal "DIAGNOSTIC" connector which is a small, rectangular-shaped grey "box", usually located near the right fender in the enigne compartment. To get codes out of this type of connector, jump the "TE1" and "E1" teminals. Finding these terminals is easy as the inside cover of the diagnostic connector contains a schematic of the connector pinouts. If the underhood emission decal (VECI) is still intact on your vehicle, the proper pins for this are outlined there as well.
The trouble codes will appear as flashes of the check engine lamp. Be sure the ignition key is on, the engine off, and your foot off of the accelerator when reading the codes. Two different codes may appear: One-digit and two digit. One digit codes have an approximate 4.5 second delay between flashes with the check engine light illuminating for about a half of a second. Mulitiple codes have a 2.5 second delay between them. For example a code two flashes the check engine lamp two times in a little over one second: I I. If two codes are stored, such as a code two and a code four, the lamp may flash as such: ....I I....I I I I. Crude examples but you get the idea. Two digit codes are similar but will flash the lamp with the first number first and the second number last. An example of a code twleve is I ....II and a code twenty four is I I..IIII.

See Figures 1 and 2
Listings of the trouble for the various engine control system covered in this manual are located in this section. Remember that a code only points to the faulty circuit, NOT necessarily to a faulty component. Loose, damaged or corroded connections may contribute to a fault code on a circuit when the sensor or component is operating properly. Be sure that the components are faulty before replacing them, especially the expensive ones.

Fig. Fig. 1: ALDL/DLC terminal identification for 1987-97 vehicles, except 1997 models with a 16-pin DLC
The Assembly Line Diagnostic Link (ALDL) or Data Link Connector (DLC) may be located under the dashboard, and is sometimes covered with a plastic cover labeled DIAGNOSTIC CONNECTOR.

  1. The diagnostic trouble codes can be read by grounding test terminal B . The terminal is most easily grounded by connecting it to terminal A (internal ECM ground). This is the terminal to the right of terminal B on the top row of the ALDL connector.
  2. Once the terminals have been connected, the ignition switch must be moved to the ON position with the engine not running.
  3. The Service Engine Soon or Check Engine light should be flashing. If it isn't, turn the ignition switch OFF and remove the jumper wire. Turn the ignition ON and confirm that the light is now on. If it is not, replace the bulb and try again. If the bulb still will not light, or if it does not flash with the test terminal grounded, the system should be diagnosed by an experienced driveability technician. If the light is OK, proceed as follows.
  4. The code(s) stored in memory may be read through counting the flashes of the dashboard warning lamp. The dash warning lamp should begin to flash Code 12. The code will display as one flash, a pause and two flashes. Code 12 is not a fault code. It is used as a system acknowledgment or handshake code; its presence indicates that the ECM can communicate as requested. Code 12 is used to begin every diagnostic sequence. Some vehicles also use Code 12 after all diagnostic codes have been sent.
  5. After Code 12 has been transmitted 3 times, the fault codes, if any, will each be transmitted 3 times. The codes are stored and transmitted in numeric order from lowest to highest.

The order of codes in the memory does not indicate the order of occurrence.
  1. If there are no codes stored, but a driveability or emissions problem is evident, the system should be diagnosed by an experienced driveability technician.
  2. If one or more codes are stored, record them. Refer to the applicable Diagnostic Code chart in this section.
  3. Switch the ignition OFF when finished with code retrieval or scan tool readings.

After making repairs, clear the trouble codes and operate the vehicle to see if it will reset, indicating further problems.

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.

How to check the trouble codes on a 2001 chrysler concorde 2 7L


I assume you are asking about the "check engine" diagonstic codes.

You can check the codes yourself by using the key and ignition switch. With the engine off, put the key in the ignition and turn it ON-OFF-ON-OFF-ON -- do not turn to the extreme right "start engine" positon, but to the last click just before the start position.
You will then see a code list read out where the odometer (mileage) usually displays. It will start with dashes in the readout "-------", then each diagnostic code will appear in sequence like P1684, P0700, and then the word "done" after all of the codes have been displayed.

One word of warning -- I have found that sometimes all of the diagnostic codes do not display with this method, so it would be best to also check the codes using an electronic diagnostic code reader. You can do this for free yourself as explained below.

Go to your nearest "national chain -- do it yourself" auto parts store such as Auto Zone or Advance Auto. Ask to borrow the "engine code reader diagnostic tool" -- you will have to give them your driver's license to borrow it. Then, in the parking lot, check the diagnostic codes yourself.

Turn the car key to the "accessory position" -- i.e., not started, but with the accessories on. Power on the diagnostic tool. Plug the attached pin connector into the Chrysler diagnostic socket located just under the dasboard below the ignition switch. Press the "read codes" button on the diagnostic tool -- you will see a diagnostic code and a brief message about what it means. Keep pressing the "next" button until you have read all of the codes.

P.S. Don't forget to get your driver's license back when you return the diagnostic tool!

Diagnostic codes for 1994 Chrysler Concorde


What you are reading is a 1-2 (12) and a 5-5 (55). The 5-5 is always at the end of the code string. The 1-2 (12) indicates that the battery was disconnected and the ECU (computer) has been reset.
