INTRODUCTION  –  REPAIR INSTRUCTION

IN

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.
