Stop Light Switch Circuit
CIRCUIT DESCRIPTION
The purpose of this circuit is to prevent the engine from stalling, while driving in lock−up condition, when
brakes are suddenly applied.
When the brake pedal is operated, this switch sends a signal to ECM. Then the ECM cancels of the lock−up
clutch while braking is in progress.
WIRING DIAGRAM
INSPECTION PROCEDURE
1 Check operation of stop light.
CHECK:
Check if the stop lights go on and off normally when the brake pedal is operated and released.
NG Check and repair stop light circuit.

Pattern Select Switch Circuit
CIRCUIT DESCRIPTION
The ECM memory contains the shift programs for the NORMAL and POWER patterns, 2 and L position and
the lock−up patterns. Following the programs corresponding to the signals from the pattern select switch,
the park / neutral position switch and other various sensors, the ECM switches the solenoid valves ON and
OFF, and control the transmission gear change and the lock−up clutch operation.

INSPECTION PROCEDURE
1 Check operation of PWR indicator light.
CHECK:
Check if the PWR indicator light normally when the pattern select switch is set to NORM and PWR position.

When using TOYOTA hand−held tester:
PREPARATION:
(a) Connect a TOYOTA hand−held tester to the DLC3.
(b) Turn the ignition switch ON and TOYOTA hand−held tes-
ter main switch ON.
CHECK:
Read the PATTERN SEL SW2 signal on the TOYOTA hand−
held tester.
OK:
Pattern select switch pushed in:
PATTERN SEL SW2 ..........ON
Pattern select switch pushed once again:

When not using TOYOTA hand−held tester:
PREPARATION:
Turn the ignition switch ON.
CHECK:
Measure voltage between terminal P of ECM and body ground
when the pattern select switch is set to the PWR (POWER)
position and NORM (NORMAL) position.
OK:

HINT:
The ECM uses the normal pattern signal if the power signal is
not input.

PROBLEM SYMPTOMS TABLE
If a normal code is displayed during the DTC check but the trouble still occurs (reappears), troubleshoot for
each problem symptom, checking the circuits for each symptom in the order given in the table below. Pro-
ceed to the page indicated for each circuit.
HINT:
If the instruction ”Proceed to next circuit inspection shown on matrix chart” 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 reappears even through there are no abnormalities in any of the other circuits, then
check or replace the cruise control ECU as the last step.
