DTC CHECK (Using a diagnosis check wire)

a. Present troubles codes:
Output the DTC.




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. Past troubles codes:
Output the DTC.

1. Using SST, connect the terminal TC and terminal CG 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.




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 2 times per second.
- Normal code indication (w/ past trouble code) When the past troubles code is stored in the airbag sensor assembly, the light blinks only ones a 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 come out at all, or if DTCs are indicated without a connection of the terminals, proceed to the "TC terminal" circuit inspection.
