Lighting system [Toyota Land Cruiser J70]

Table for checking the warning system for the presence of switched-on lighting devices.

Adjusting the headlight position

Note: For headlights equipped with an electric leveling system, before adjusting, turn the control switch to the "O" position to return the headlights to their original position.

Combination switch

Note: The location of the switch on right-hand drive models is symmetrical to its location on left-hand drive models.

1. Checking the switch.

a) Check the conductivity of the external lighting switch.



b) Check the conductivity of the headlight switch.



c) Check the continuity of the turn signal switch.





d) Check the conductivity of the hazard warning switch.





d) Replace the combination switch if the conductivity is different from that given in the tables.

2. Checking the relay in the relay box.

a) Check the conductivity of the headlight control relay.





b) Check the conductivity of the rear side light relay.





c) Check the conductivity of the headlight switching relay.





d) Replace the relay if the conductivity differs from the specified value.

Fog lights

1. Checking the front fog light switch.





2. Checking the rear fog light switch.

3. Checking the rear fog light relay.

Direction indicators and hazard warning lights

1. For checking the direction indicator and hazard warning lights switches, see the "Combination switch" subsection.

2. Checking the turn signal relay.

a) Connect the battery to terminals 2 (+) and 3 (-) of the relay.

b) Connect both turn signal lamps in parallel to terminals 1 and 3, make sure that the lamps flash at a frequency of 60-120 times per minute.





c) If one of the direction indicator lamps burns out, the flashing frequency increases to 140 times per minute.

3. Checking the emergency signal relay.

Warning system for the presence of switched-on lighting devices

1. Check the operation of the system relay.

a) Connect the battery to terminals 3 (+) and 4 (-).



b) Switch the battery positive from terminal 2 to terminal 1: the buzzer should not work.



c) Disconnect the battery positive from terminal 1 or 2: the buzzer should sound.



2. Checking the wiring.

a) Disconnect the relay connector.

b) Check the connector from the wire bundle side as shown in the table.



c) If the parameters of the electric circuit do not correspond to those described in the table, replace the relay. Repeat the check after replacing the relay and, if the parameters of the circuit again do not correspond to the data in the table, check the circuits of other devices.

3. Checking the driver's door limit switch (models without door open warning system).

a) Check for continuity between the connector and the switch housing when the switch is in the "ON" position (button released).


b) Check for continuity between the connector and the switch housing when the switch is in the "OFF" position (button pressed).

c) Replace the switch if it does not operate as specified.

Electric headlight adjustment

1. Check the switch conductivity. Replace the switch if the conductivity is different from the table.





2. Checking the electric drive.

a) Connect the battery to terminals 6 (+) and 5 (-).

b) Close each terminal to ground one by one and check the operation of the drive in different modes.

Terminal	Headlight beam position
1 - "earth"	"0"
2 - "earth"	"1"
3 - "earth"	"2"
4 - "earth"	"3"
7 - "earth"	"4"
8 - "earth"	"5"

c) Replace the electric drive if it does not operate as specified.
