HINT:
If a normal code is displayed during the DTC check but the trouble still o\
ccurs, check the circuits for each
symptom in the order given in the charts on the following pages and proceed to \
the page given for trouble-
shooting.
The Matrix Chart is divided into 3 chapters.

If the instruction ºProceed to next circuit inspection shown on matri\
x chartº is given in the flow chart
for each circuit, proceed to the circuit with the next highest number in the table to continue the check.

If the trouble still occurs even though there are no abnormalities in any of the other circuits, then ch\
eck
and replace the ECM.

PRE±CHECK
1.DIAGNOSIS SYSTEM
(a)Check the PS warning light.
(1)When the ignition switch is turned ON, check thatthe PS warning light goes on for 2 seconds.
HINT:
If the indicator check result is not normal, proceed to trouble-
shooting for the PS warning light circuit (See page 05±1082).
2.DTC CHECK (USING SST CHECK WIRE)
(a)Checking DTCs using a SST check wire. SST09843±18040
(1)Using SST, connect terminals Tc and CG of theDLC3.
(2)Turn the ignition switch to ON.
(3)Read and record any DTCs from the P/S warning light on the combination meter. Refer to the chart on
the left for examples of a normal code and codes 21
and 22.
HINT:

If the P/S warning light does not blink any DTC codes or
the normal code, inspect the circuit shown in the charts
below.

(3) Read the DTCs by following the prompts on the tes-
ter screen.
HINT:
Refer to the hand±held tester operator's manual for further de-
tails.
(b) Clearing the DTCs using the hand±held tester.
(1) Connect the hand±held tester to the DLC3.
