DTC CHECK (Using diagnosis check wire)




a. Present troubles codes:
Output the DTC.

1. Turn the ignition switch to ON, and wait for approx. 60 seconds.
2. Using SST, connect terminal Tc and CG of the DLC3.
SST 09843-18040

NOTE: Pay attention to the terminal connecting position to avoid a malfunction.

b. Past troubles codes:
Output the DTC.

1. Using SST, connect terminal Tc and CG of the DLC3.
SST 09843-18040

2. Turn the ignition switch to ON, and wait for approx. 60 seconds.

NOTE: Pay attention to the terminal connecting position to avoid a malfunction.




c. Read the DTC.
Read the DTC by connecting the blinking times. As an example, the blinking patterns of normal, 11 and 31 are shown in the illustration.

- Normal code indication
The light blinks 2 times per second.

- Malfunction code indication
The first blinking indicates the first DTC. Second blinking occurs after 1.5-second of pausing.

If there are 2 or more codes, there will be a 2.5-second pause between each code. After all the codes are shown, there will be a 4.0-second pausing, and they will all be repeated.

HINT:
- If 2 or more malfunctions are found, the indication starts from the smaller numbered code.
- If the light does not blink or comes out at all, or if DTCs are indicated without a connection of the terminals, proceed to the "Tc terminal circuit inspection".
