HINT:
•

When the compass display returns to the
outside temperature display, the calibration is
complete.

•

When the circling calibration fails, "Er" is
displayed for about 2 seconds and then the
COMPASS indicator flashes.

•

If the correct direction is not displayed after
driving the vehicle as specified, change the
vehicle location.

•

To cancel the calibration before completion,
push the SET button for about 2 seconds.

(5) If enough space is not available to drive in a

circle, perform the following:
1. Perform a four-point turn within 2 minutes, as

shown in the illustration.

NOTICE:
•

Do not perform the circling calibration of
the compass in a place where the earth's
magnetic field is subject to interference by
artificial magnetic fields (underground
parking, under a steel tower, between
buildings, roof parking, near a crossing,
near a large vehicle, etc.).

•

During the calibration, do not operate any
electric systems (power window, etc.) as
they may interfere with the calibration.

HINT:
•

When the compass display returns to the
outside temperature display, the calibration is
complete.

•

When the circling calibration fails, "Er" is
displayed for about 2 seconds and then the
COMPASS indicator flashes.

•

If the correct direction is not displayed after
driving the vehicle as specified, change the
vehicle location.

•

To cancel the calibration before completion,
push the SET button for about 2 seconds.

(6) Check that the COMPASS indicator is not

blinking and that the compass is displayed
normally.

HOW TO TROUBLESHOOT ECU
CONTROLLED SYSTEMS

GENERAL INFORMATION

A large number of ECU controlled systems are used in the FJ
CRUISER. In general, ECU controlled systems are
considered to be very intricate, requiring a high level of
technical knowledge to troubleshoot. However, most problem
checking procedures only involve inspecting the ECU
controlled system's circuits one by one. An adequate
understanding of the system and a basic knowledge of
electricity is enough to perform effective troubleshooting,
accurate diagnoses and necessary repairs.
FOR USING INTELLIGENT TESTER

Connect the cable of the intelligent tester (with CAN VIM)
to the DLC3, turn the ignition switch ON and attempt to
use the tester. If the display indicates that a
communication error has occurred, there is a problem
either with the vehicle or with the tester.
* If communication is normal when the tester is

connected to another vehicle, inspect the DLC3 of the
original vehicle.

* If communication is still not possible when the tester is

connected to another vehicle, the problem may be in
the tester itself. Consult the Service Department listed
in the tester's instruction manual.

HOW TO PROCEED WITH
TROUBLESHOOTING

1.

OPERATION FLOW
HINT:
Perform troubleshooting in accordance with the
procedures below. The following is an outline of basic
troubleshooting procedures. Confirm the troubleshooting
procedures for the circuit you are working on before
beginning troubleshooting.

NEXT

(a) Ask the customer about the conditions and environment

when the problem occurred.

NEXT

Standard voltage:

11 to 14 V

If the voltage is below 11 V, recharge or replace the battery
before proceeding.

NEXT

(a) Visually check the wire harnesses, connectors and fuses

for open and short circuits.

(b) Warm up the engine to the normal operating

temperature.

(c) Confirm the problem symptoms and conditions, and

check for DTCs.

(a) Check the results obtained in "SYMPTOM

CONFIRMATION AND DTC (AND FREEZE FRAME
DATA) CHECK". Then find the output DTC in the DTC
chart. Look at the "Trouble Area" column for a list of
potentially malfunctioning circuits and / or parts.

NEXT

(a) Check the results obtained in "SYMPTOM

CONFIRMATION AND DTC (AND FREEZE FRAME
DATA) CHECK". Then find the problem symptoms in the
problem symptoms table. Look at the "Suspected Area"
column for a list of potentially malfunctioning circuits and
/ or parts.

NEXT

(a) Confirm the malfunctioning circuit or part.

NEXT

(a) Adjust, repair or replace the malfunctioning circuit or

parts.

NEXT

(a) After the adjustment, repairs or replacement, confirm

that the malfunction no longer exists. If the malfunction
does not reoccur, perform a confirmation test under the
same conditions and in the same environment as when
the malfunction occurred the first time.
