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 service wire, 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 2-digit DTC as indicated by the number of times the SRS warning light blinks. As an example, the blinking patterns, normal, 11 and 31 are shown in the illustration.
- Normal code indication (w/o past trouble code)
The light will blink 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 comes out at all, or if DTCs are indicated without a connection of the terminals, proceed to the "TC terminal circuit".
