Description
The purpose of this circuit is to prevent the engine from stalling while driving in the lock-up condition when the brakes are suddenly applied.
When the brake pedal is depressed, this switch sends a signal to the ecm. Then the ecm cancels the operation of the lock-up clutch while braking is in progress.
Monitor description
This dtc indicates that the stop light switch remains on. When the stop light switch remains on during go and stop driving, the ecm interprets this as a fault in the stop light switch. Then the mil illuminates and the ecm stores the dtc. The vehicle must go (30 km/h (18.63 Mph) or more) and stop (less than 3 km/h (1.86 Mph)) 5 times for 2 driving cycles in order for the dtc to be output.

Inspection procedure
Hint:
Using the intelligent tester's data list allows switch, sensor, actuator and other item values to be read without removing any parts. Reading the data list early in troubleshooting is one way to save time.
Notice:
In the table below, the values listed under "normal condition" are reference values. Do not depend solely on these reference values when deciding whether a part is faulty or not.

Shift position purpose
*1: Shifting the shift lever to d allows the system to select a gear suitable
for
the driving conditions.
Setting the shift lever to d is recommended for normal driving.
*2: Selecting shift ranges using s mode restricts the upper limit of the
possible
gear ranges, controls engine bra ...

Fail-safe function
When communication fails in any of the main wires
(communication lines) due to a short circuit or other
causes, the fail-safe function, which is specified for
each system, operates to prevent the system from
malfunctioning.

Inspect brake lines and hoses
Hint:
Work in a well-lighted area. Turn the front wheels fully to
the right or left before beginning the inspection.
Using a mirror, check the entire circumference and
length of the brake lines and hoses for:
Damage
