DESCRIPTION
The stop light switch is a duplex system that transmits two signals: STP and ST1-. These two signals are
used by the ECM to monitor whether or not the brake system is working properly. If the signals, which
indicate the brake pedal is being depressed or released, are detected simultaneously, the ECM interprets
this as a malfunction in the stop light switch and sets the DTC.
HINT:
The normal conditions are as shown in the table below. The signals can be read using the intelligent
tester.
MONITOR DESCRIPTION
This DTC indicates that the stop light switch remains on. When the stop light switch remains ON during
"stop and go" driving, the ECM interprets this as a fault in the stop light switch and the MIL comes on and
the ECM stores the DTC. The vehicle must stop (less than 2 mph (3 km/h)) and go (19 mph (30 km/h) or
more) 5 times for two driving cycles in order to detect a malfunction.

MONITOR DESCRIPTION
The battery supplies electricity to the ECM even when the ignition switch is off. This power allows the
ECM to store data such as DTC history, freeze frame data and fuel trim values. If the battery voltage falls
below a minimum level, these memories are cleared and the ECM determines that there is a malfunction
in the power supply circuit. When the engine is next started, the ECM illuminates the MIL and sets the
DTC.
HINT:
If DTC P0560 is set, the ECM does not store other DTCs.

INSPECTION PROCEDURE
HINT:
Read freeze frame data using the intelligent tester. The ECM records vehicle and driving condition
information as freeze frame data the moment a DTC is stored. When troubleshooting, freeze frame data
can be helpful in determining whether the vehicle was running or stopped, whether the engine was
warmed up or not, whether the air-fuel ratio was lean or rich, as well as other data recorded at the time of
a malfunction.
(a) Remove the EFI No. 1 fuse from the engine room
junction block.
(b) Measure the resistance according to the value(s) in the
table below.
Standard resistance:
Below 1
(c) Reinstall the EFI No. 1 fuse.
