CIRCUIT DESCRIPTION
The O/D main switch contacts go open when the switch is pushed in and go closed when it is pushed out.
In O/D main switch in OFF position, the O/D OFF indicator light lights up, and the ECM prohibits shifting over-
drive.

PRE±CHECK
1. DIAGNOSIS SYSTEM
(a) Check the indicator.
When the ignition switch is turned ON, check that the ABS
warning light goes on for 3 seconds.
HINT:
If the indicator check result is not normal, proceed to trouble-
shooting for the ABS warning light circuit (See page DI±213).
(b) Check the DTC.
(1) Disconnect the short pin from DLC1.
(2) Using SST, connect terminals Tc and E
1 of DLC2 or
DLC1.
SST 09843 ± 18020
(3) Turn the ignition switch ON.
(4) Read the DTC from the ABS warning light on the
combination meter.
HINT:

If no code appears, inspect the diagnostic circuit or ABS
warning light circuit (See page DI±216 or DI±213).

As an example, the blinking patterns for normal code and
codes 11 and 21 are shown on the left.
(5) Codes are explained in the code table on page
DI±181.
(6) After completing the check, disconnect terminals Tc
and E
1, and turn off the display.
If 2 or more malfunctions are indicated at the same time the low-
est numbered DTC will be displayed 1st.

(c) Using TOYOTA hand±held tester, check the DTC.
(1) Hook up the TOYOTA hand±held tester to the
DLC2.
(2) Read the DTC by following the prompts on the tes-
ter screen.
Please refer to the TOYOTA hand±held tester oper-
ator 's manual for further details.
(d) Clear the DTC.
(1) Using SST, connect terminals Tc and E
1 of DLC2 or
DLC1 and remove the short pin from DLC1.
SST 09843 ± 18020
(2) Turn the ignition switch ON.
(3) Clear the DTC stored in ECU by depressing the
brake pedal 8 or more times within 5 seconds.
(4) Check that the warning light shows the normal
code.
(5) Remove the SST from the terminals of DLC2 or
DLC1.
SST 09843 ± 18020
(6) Connect the short pin to DLC1.
(e) Using TOYOTA break±out±box and TOYOTA hand±held
tester, measure the ECU terminal values.
(1) Hook up the TOYOTA hand±held tester and
TOYOTA break±out±box to the vehicle.
(2) Read the ECU input/output values by following the
prompts on the tester screen.
HINT:
TOYOTA hand±held tester has a ºSnapshotº function. This re-
cords the measured values and is effective in the diagnosis of
intermittent problems.
Please refer to the TOYOTA hand±held tester/TOYOTA break±
out±box operator's manual for further details.
