DTC CHECK / CLEAR
1. DTC CHECK (USING SST CHECK WIRE)
(a) Check DTCs.
(1) Using the SST, connect terminals TC and CG of
DLC3.
SST 09843±18040
(2) Turn the ignition switch to the ON position.
(3) Read and record any DTCs from the tire pressure
warning lamp on the combination meter. Refer to
the illustration on the left for examples of a normal
system code and codes 13 and 33.
HINT:

If the tire pressure warning lamp does not blink any DTCs
or the normal system code, inspect the tire pressure
warning lamp circuit or TC terminal circuit.
Trouble AreaSee page

TC terminal circuitDI±888

If 2 or more malfunctions are indicated at the same time,
the lowest numbered DTC is displayed first.
(4) Refer to the Diagnostic Trouble Code Chart (see
page DI±825) for DTC information.
(5) After completing the check, turn the ignition switch
off and remove the SST from DLC3.
SST 09843±18040
2. DTC CHECK (USING HAND±HELD TESTER)
(a) Check DTCs.
(1) Connect the hand±held tester to the DLC3.
(2) Turn the ignition switch to the ON position.
(3) Read the DTCs following the prompts on the tester
screen.
HINT:
Refer to the hand±held tester operator's manual for further de-
tails.
