Toyota Sienna Service Manual: DTC check / clear
1. DTC CHECK (USING SST CHECK WIRE)

- Check the DTCs (Present trouble code).
- Turn the ignition switch ON, and wait for
approximately 60 seconds.
- Using SST, connect terminals TC and CG of the
DLC3.
SST 09843-18040
NOTICE:
Connect the terminals to the correct
positions to avoid a malfunction.
- Check the DTCs (Past trouble code).
- Using SST, connect terminals TC and CG of the
DLC3.
SST 09843-18040
NOTICE:
Connect the terminals to the correct
positions to avoid a malfunction.
- Turn the ignition switch ON, and wait for
approximately 60 seconds.

- Read the DTCs.
- Read the blinking patterns of the DTCs. As
examples, the blinking patterns for the normal
system code and trouble codes 11 and 31 are
shown in the illustration.
- Normal system code indication (w/o past
trouble code)
The light blinks twice per second.
- Normal system code indication (w/ past
trouble code)
When the past trouble code is stored in the
center airbag sensor assembly, the light
blinks only once per second.
- Trouble code indication
The first two blinkings indicate the first DTC.
The second blinking occurs after a 1.5-
second pause.
If there are more than 1 code, 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 all will be repeated.
HINT:
- If 2 or more malfunctions are found, the
indication begins with the smaller numbered
code.
- If DTCs are indicated without connecting the
terminals, proceed to the "Diagnosis Circuit"
2. DTC CLEAR (USING SST CHECK WIRE)
- Clear the DTCs.
- When the ignition switch is turned off, the DTCs
are cleared.
HINT:
Depending on the DTC, the code may not be
cleared by turning off the ignition switch. In this
case, proceed to the next procedure.
- Using SST, connect terminals TC and CG of the
DLC3, and then turn the ignition switch to the
ON position.
SST 09843-18040
- Disconnect terminal TC of the DLC3 within 3 to
10 seconds after the DTCs are output, and
check if the SRS warning light comes on after 3
seconds.
- Within 2 to 4 seconds after the SRS warning
light comes on, connect terminals TC and CG of
the DLC3.
- The SRS warning light should go off within 2 to 4
seconds after connecting terminals TC and CG
of the DLC3. Then, disconnect terminal TC
within 2 to 4 seconds after the SRS warning light
goes off.
- The SRS warning light comes on again within 2
to 4 seconds after disconnecting terminal TC.
Then, reconnect terminals TC and CG of the
DLC3 within 2 to 4 seconds after the SRS
warning light comes on.
- Check if the SRS warning light goes off within 2
to 4 seconds after connecting terminals TC and
CG of the DLC3. Also check if the normal
system code is output within 1 second after the
SRS warning light goes off.
If DTCs are not cleared, repeat this procedure
until the codes are cleared.
