BATTERY TESTING PROCEDURE
TEST STEP
(1) Turn headlamps on for 15 seconds.
(2) Turn headlamps off for 2 minutes to allow battery voltage to
stabilize.
(3) Disconnect cables.
Read open circuit voltage.
OK:Open circuit voltage is more than 12.4 VNGCharge battery at 5 amps. (see LOAD TEST RATE CHART)
RetestOK
(1) Connect a load tester to the battery.
(2) Load the battery at the recommended discharge rate (see LOAD
TEST RATE CHART).
(3) Read voltage after 15 seconds, then remove load.
(4) Compare the measured value with the minimum voltage (see
LOAD TEST CHART).
OK:Higher than minimum voltageNG
Replace battery

The key reminder warning buzzer dose not stop
sounding even if the key is removed. (However, it
stops when the driver’s side door is closed.)454-9
The key reminder warning buzzer does not sound
ever if the driver’s side door is opened while the key
is still inserted. (However, the ignition key should be
in the OFF position.)554-10
NOTE
If every input signal can not be checked with the MUT-II, a diagnosis circuit system failure is probably
the cause.

INSPECTION PROCEDURE FOR TROUBLE SYMPTOMS
Inspection Procedure 1
Key hole illumination lamp remains illuminated.
Probable cause
The cause is probably a harness short or a defective ETACS-ECU or buzzer ECU.
Malfunction of harness wire

Malfunction of ETACS-ECU

Malfunction of buzzer ECU
Disconnect the ignition key cylinder illumination lamp connector
B-84 and measure the continuity:

Between 4 and body earth
OK:ConductingNGCheck the harness wire between the ignition key cylinder illumination
lamp and junction block, and repair if necessary.
OK
Replace the ETACS-ECU or buzzer ECU.
Inspection Procedure 2
Even if driver’s side door is opened, key hole illumination
lamp does not illuminate.
Probable cause
The cause is probably a defective key hole illumination lamp circuit system, or a
defective driver’s side door switch input circuit system if the ignition key reminder
warning buzzer is also faulty.
Malfunction of driver’s side door switch

Malfunction of bulb

Malfunction of connector

Malfunction of harness wire

Inspection Procedure 3
While key hole illumination lamp is illuminated, ignition
key is turned to the ON position but key hole illumination
lamp does not switch off. (However, it switch off after 15
seconds.)
Probable cause
While the key reminder warning buzzer is sounding, the
ignition key is turned to the ON position but the sound
dose not stop. (However, it stops when the driver’s side
door is closed.)
The cause is probably a malfunction of the ignition switch input circuit, ETACS-ECU
or buzzer ECU. Furthermore, if there is a malfunction of a multipurpose fuse, the
cause may also be a short circuit in a harness.

Inspection Procedure 5
The key reminder warning buzzer dose not sound even if
the driver’s side door is opened while the key is still
inserted. (However, the ignition key should be in the OFF
position.)
Probable cause
The cause is probably a malfunction of the door switch input circuit system, if the
key hole illumination lamp is also faulty. A malfunction of the key reminder switch
input circuit system is also suspected.

FUEL GAUGE SIMPLE CHECK
Remove the fuel gauge unit connector.
Use the special tool to connect a test
lamp (12 V – 3.4 W) to the harness
connector. (Refer to Fig.1)
When the ignition switch is turned to
ON, the test lamp illuminates.OKThe needle of the fuel gauge moves.OKReplace the fuel gauge unit.
NG

Repair the harness.
FUEL GAUGE UNIT CHECK
Remove the fuel gauge unit from the fuel tank.
FUEL GAUGE UNIT RESISTANCE
1. Check that resistance value between the fuel gauge unit
terminal and earth terminal is at standard value when
fuel gauge unit float is at point F and point E.
Standard value:
Float positionMainSub
Point F1.8 ±1.2 Ω1.2 ±0.8 Ω
Point E65.2 ±4 Ω44.8 ±8 Ω
2. Check that resistance value changes smoothly when float
