Glass breakage sensor ECU circuit
CIRCUIT DESCRIPTION
The glass breakage sensor microphone detects the sound of metal (and other) objects striking the windows
and outputs a signal to the glass breakage sensor ECU. Sound of breaking window glass is amplified (fixed
frequency) by the resonator provided in front of the microphone.
The glass breakage sensor ECU receives a signal from the glass breakage sensor microphone. If the signal
matches the specification, the ECU outputs the glass breakage signal to the body ECU.
The body ECU receives the signal from the glass breakage sensor ECU and outputs a warning.

CHECK MODE PROCEDURE
1. WARNING FOR A/C COMPRESSOR LOCK
If compressor lock occurs during A/C operation, the A/C switch
indicator on the A/C control assembly starts blinking.
When this occurs, check for compressor lock (DTC 22) using
diagnosis trouble code check then proceed to inspect the circuit
or the component.
Compressor lock sensor circuit. " (See page DI±2339)
2. LIST OF OPERATION METHODS
By operating each of the A/C control switches as shown in the diagram below, it is possible to enter the diag-
nosis check mode.

Check that the arrow mark on the belt tensioner falls
within area A of the scale.
If it is outside area A, replace the drive belt.
HINT:

When a new belt is installed, it should lie within area B. If
not, the drive belt is not correct.

After installing a belt, check that it fits properly in the
ribbed grooves.

Check by hand to confirm that the belt does not slipped
out of the groove on the bottom of the pulley.
6. REMOVE ENGINE UNDER COVER NO.1
7. VISUALLY CHECK GENERATOR WIRING AND LIS-
TEN FOR ABNORMAL NOISES
(a) Check that the wiring is in good condition.
(b) Check that there is no abnormal noise from the generator
while the engine is running.
8. CHECK CHARGE WARNING LIGHT CIRCUIT
(a) Warm up the engine and then turn it off.
(b) Switch off all accessories.
(c) Turn the ignition switch ON, and check that the charge
warning light comes on.
(d) Start the engine, and check that the light goes off.
If the light does not go off as specified, troubleshoot the charge
light circuit.
9. INSPECT CHARGING CIRCUIT WITHOUT LOAD
HINT:
If a battery/generator tester is available, connect the tester to
the charging circuit as per manufacturer's instructions.
(a) If a tester is not available, connect a voltmeter and amme-
ter to the charging circuit as follows:

Disconnect the wire from terminal B of the genera-
tor, and connect it to the negative (±) tester probe
of the ammeter.

Connect the positive (+) tester probe of the amme-
ter to terminal B of the generator.

Connect the positive (+) tester probe of the voltme-
ter to terminal B of the generator.

Ground the negative (±) tester probe of the voltme-
ter.
(b) Check the charging circuit as follows:
With the engine running from idling to 2,000 rpm, check
the reading on the ammeter and voltmeter.
Standard amperage: 10 A or less
Standard voltage: 13.2 to 14.0 V

PRECAUTION
1. REMOVAL AND INSTALLATION OF TIRE PRESSURE MONITOR VALVE SUB±ASSY
(a) When installing a tire, make sure that the tire pressure monitor valve does not interfere with the tire
bead in order to prevent damage to the sensor.
(b) After completing the operation, remove the valve core to rapidly release air and check that the warning
light comes on. If not, the system may have a defect.
(c) If there is air leakage, tighten the nut with a force of 4.0 NVm (41 kgfVcm, 35 in.Vlbf) and push the valve
core 2 or 3 times to remove any dirt attached to the valve core.
If there is still air leakage, replace the grommet, the washer and the nut all together.
(d) When installing the tire pressure monitor valve, check whether the rim, grommet, washer and nut are
clean. Use a manufacturer±specified cap.
(e) When putting air into the tire, first install the tire pressure valve straight onto the stem of the tire pres-
sure monitor valve.
2. TIRE AND WHEEL REPLACEMENT OR TIRE ROTATION
(a) When replacing tires, be sure to check if the grommet of the tire valve is damaged. If so, replace the
grommet together with the washer and nut.
(b) When tires and wheels are replaced, make sure to register the transmitter ID.
