DTC P0504 BRAKE SWITCH ºAº/ºBº CORRELATION
CIRCUIT DESCRIPTION
In this system, the signal of the stop light switch is used to judge whether the acceleration system is abnormal
or not.
The stop light switch has a duplex system (signals STP and ST1±) to memorize the abnormality when the
signals of depressing and releasing the brake pedal are detected simultaneously.

DTC P0500 VEHICLE SPEED SENSOR ºAº
CIRCUIT DESCRIPTION
The speed sensor for skid control ECU detects the wheel speed and sends the appropriate signals to the
skid control ECU.
The skid control ECU converts these signals into a 4±pulse signal and outputs it to the combination meter.
After this signal is converted into a more precise rectangular waveform by the waveform shaping circuit in-
side the combination meter,it is then transmitted to the ECM. The ECM determines the vehicle speed based
on the frequency of these pulse signals.
DTC No.DTC Detection ConditionTrouble Area

7. ACTIVE TEST
HINT:
Performing the ACTIVE TEST using the hand±held tester allows the relay, VSV, actuator and so on to oper-
ate without parts removal. Performing the ACTIVE TEST as a first step of troubleshooting is one of the meth-
ods to shorten diagnostic time.
It is possible to display the DATA LIST during the ACTIVE TEST.
(a) Warm up the engine.
(b) Turn the ignition switch OFF.
(c) Connect the hand±held tester to the DLC3.
(d) Turn the ignition switch ON.
(e) Push the ºONº button of the hand±held tester.
(f) Select the item ºDIAGNOSIS / OBD/MOBD / ACTIVE TESTº
