In a nutshell, to get the trouble codes stored in your Camry's fuel injection computers's memory, we need to jumper together 2 specific terminals of the diagnostic link connector (DLC). Your Toyota Camry will then flash the malfunction indicator light (MIL -also known as the check engine light CEL) and flash the trouble code to you.

The DLC is located on the bottom left of your Camry's dashboard. To see a photo of the DLC, go to:

These are the steps to retrieve the trouble codes:

  1. Make sure your battery is fully charged before starting (its customary to place a charger on the battery while retrieving trouble codes to keep the battery from discharging).
  2. Turn the key to the On position but don't start the vehicle.
  3. Jumper terminals TE1 and E1 of the diagnostic link connector that's located on the bottom left (driver-side) of your Camry's dash.
  4. Count the number of flashes of the malfunction indicator light (MIL).
  5. If no trouble codes are present:
    1. The MIL will flash continuously and evenly (see illustration below).
  6. If trouble codes are present:
    1. The MIL will flash the trouble codes in a specific pattern.
    2. The digits of the trouble code will be flashed at about 1/2 (.5) second intervals. A 1 1/2 (1.5) second pause will separate first and second digits of the code (see illustration above).
    3. If more than one trouble code is stored, a 2 1/2 (2.5) second pause will separate the next flashed trouble code.
    4. Once all trouble codes are flashed. a 4 1/2 (4.5) second pause will occur. After this 4.5 second pause, the trouble codes will be repeated.
    5. Trouble codes are flashed in order of smallest to largest number.

Once you've confirmed and written down the trouble codes, remove the jumper wire from the diagnostic link connector (DLC) and turn the key to the Off position.
