DTC CHECK (Using diagnosis check wire)




a. Output the DTC (Present trouble codes).

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

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

b. Output the DTC (Past trouble codes).

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

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




c. Read the DTC.
1. Read the DTC by counting the blinking times. As an example, the blinking patterns of normal, 11 and 31 are shown in the illustration.
- Normal code indication (w/o past trouble code)
The light blinks twice per second.
- Normal code indication (w/ past trouble code) When the past trouble code is stored in the airbag sensor assy center, the blinks only once a second.
- Malfunction code indication
The first blinking indicates the first DTC. Second blinking occurs after 1.5-second of pause.

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