Displaying & Reading Trouble Codes

NOTE: This is the only information provided by the manufacturer for reading trouble codes for this system.

DTC CHECK (Using diagnosis check wire)




a. Present trouble codes:
Output the DTC.

1. Turn the ignition switch to the ACC or ON position and wait for approx. 20 seconds.
2. Using SST, connect terminals Tc and E1 of the [1][2]DLC1.
SST 09843-18020

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

b. Past trouble codes:
Output the DTC.

1. Using SST, connect terminals Tc and E1 of the [1][2]DLC1.
SST 09843-18020

2. Turn the ignition switch to the ACC or ON position and wait for approx. 20 seconds.

NOTE: Pay due 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
The light will blink 2 times per second.

- Malfunction code indication
The first blinking output indicates the first digit of a 2-digit DTC. After a 1.5-second pause, the second blinking output will indicate digit.




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

HINT:
- In the event of a number of trouble codes, indication will start from the smallest numbered code.
- If a DTC is not output or a DTC is output without terminal connection, proceed to the Tc terminal circuit inspection.

DTC CHECK (Using TOYOTA hand-held tester)




a. Hook up the TOYOTA hand-held tester to the [1][2]DLC1 or DLC3.
b. Read the DTCs by following the prompts on the tester screen.

HINT: Please refer to the TOYOTA hand-held tester operator's manual for further details.
