THEFT WARNING SIREN CIRCUIT
CIRCUIT DESCRIPTION
The theft warning siren has an internal battery. If any of the vehicle's battery or communication line is opened,
the theft warning siren detects it by itself and sounds. Although the theft warning siren sounds by receiving
a signal from the theft deterrent ECU usually, the theft warning siren can sound by its internal battery in case
that the vehicle's battery is opened.
The theft deterrent ECU sends an arming signal to the theft warning siren while transferring to the armed
state, and it also sends a disarming signal to the siren while transferring to the disarmed state. Besides, the
theft deterrent ECU can cause the theft warning siren to sound by sending an alarm signal in the alarm
sounding state.

HINT:
The ECM provides a pulse width modulated control circuit to adjust current through the heater. The heated
oxygen sensor heater circuit uses a relay on the B+ side of the circuit.

INSPECTION PROCEDURE
HINT:
SIf different DTCs related to different systems that have terminal E2 as the ground terminal are output
simultaneously, terminal E2 may have an open circuit.
SRead freeze frame data using the hand−held tester . Freeze frame data records the engine conditions
when a malfunction is detected. When troubleshooting, freeze frame data can help determine if the
vehicle was running or stopped, if the engine was warmed up or not, if the air −fuel ratio was lean or
rich, and other data from the time the malfunction occurred.

CHECK ENGINE WARNING LIGHT CIRCUIT
CIRCUIT DESCRIPTION
The CHK ENG is used to indicate the ECM’s detection of a vehicle malfunction.
The instrument panel IGN fuse provides the circuit power and the ECM provides the circuit ground that illumi-
nates the CHK ENG.
CHK ENG operations should be checked visually:
The CHK ENG should be illuminated when the ignition is first turned to ON. If the CHK ENG is always ON
or OFF, use the hand−held tester and follow the procedures below to determine the cause of the problem.

INSPECTION PROCEDURE
HINT:
Troubleshoot each trouble symptom in accordance with the chart below.
CHK ENG remains onStart inspection from step1
CHK ENG is not illuminatedStart inspection from step 3
