Toyota Tundra Service Manual: Adjustment

ADJUSTMENT

CAUTION / NOTICE / HINT

CAUTION:

Radiofrequency radiation exposure information:

• This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment.
• This equipment should be kept with minimum distance of 20 cm (7.87 in.) between the radiator (antenna) and your body at all times during adjustment.
• This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter.

PROCEDURE

1. PREPARATION FOR MILLIMETER WAVE RADAR SENSOR ASSEMBLY ADJUSTMENT

(a) Park the vehicle on a level surface where the area in front of the vehicle shown in the illustration is free of metal objects.

*a	5 m (16.4 ft.)
*b	6 m (19.7 ft.)
*c	4 m (13.1 ft.)
*d	2 m (6.56 ft.)
	Do not place any metal objects in this area
	Do not place metal objects with a height of more than 50 mm (1.97 in.) in this area

HINT:

Metal objects with a height of 50 mm (1.97 in.) or less placed within the area shown in the illustration will not affect the adjustment.

(b) Check the levelness of the ground.

(1) Check the levelness of the ground at the 3 points shown in the illustration.

*a	3 m (9.84 ft.)
	Levelness Check Point

(2) Place the level on each levelness check point and check that the air bubble of the level is centered.

(c) Adjust the tire inflation pressure to the specified pressure.

(d) Clean the radiator grill garnish or millimeter wave radar sensor assembly.

(e) Visually inspect the front of the vehicle.

HINT:

Confirm that there is no damage or deformation.

(f) Check that the radiator grill garnish and millimeter wave radar sensor assembly is clean and there is no dirt or snow covering them.

(g) Visually inspect the front bumper cover, radiator grille sub-assembly and stays.

HINT:

Confirm that there is no damage or deformation.

2. ADJUST MILLIMETER WAVE RADAR SENSOR ASSEMBLY VERTICALLY AND HORIZONTALLY

(a) Adjust SST (reflector) height.

(1) Adjust SST (reflector) so that the center of SST (reflector) is the same height as the millimeter wave radar sensor assembly. HINT: Make sure to align the center of SST (reflector) with the millimeter wave radar sensor assembly (the center of the emblem). Reference Value: Radiator Grille Sub-assembly Specified Condition for Type A 970 mm (3.18 ft.) for Type B 986 mm (3.23 ft.) for Type C 931 mm (3.05 ft.) SST: 09870-60000 09870-60010 SST: 09870-60040

*a SST (reflector)

(b) Place SST (reflector).

(1) Hang a weight with a pointed tip from the center of the tail gate handle, and mark the rear center point of the vehicle (point A) on the ground.

HINT:

Lightly flick the string with your fingers several times to confirm that the string is perpendicular to the ground.

(2) Hang a weight with a pointed tip from the center of the radiator grille garnish, and mark the front center point of the vehicle (point B) on the ground (placement position).

1. for Type A:

   *a	String	*b	Weight
   *c	Center	*d	Bilateral Symmetry

2. for Type B:

   *a	String	*b	Weight
   *c	Center	*d	Bilateral Symmetry

3. for Type C:

   *a	String	*b	Weight
   *c	Center	*d	Bilateral Symmetry

HINT:

Lightly flick the string with your fingers several times to confirm that the string is perpendicular to the ground.

(3) Using tape and a string, create a line that connects point B to point A and extends at least 3000 mm (9.84 ft.) beyond the front center point of the vehicle.

HINT:

• Make sure the string is taut when securing it with tape.
• Lightly flick the string with your fingers several times to confirm that the string is aligned with point B.

(4) Mark point C (SST (reflector) placement position) at a position 3000 mm (9.84 ft.) from point B.

(5) Place SST (reflector) at point C.

(c) Front Beam Axis Adjustment:

NOTICE:

• Close all of the doors.
• Ensure that nobody enters the adjustment area during the adjustment.
• Do not move or shake the vehicle during adjustment (do not get in or out of the vehicle).
• During the procedure, do not enter the adjustment area.
• Do not turn off the Techstream or ignition switch.

(1) Connect the Techstream to the DLC3.

(2) Turn the ignition switch on (IG).

(3) Turn the Techstream on and turn the cruise control system on using the cruise control main switch (ON/OFF button).

(4) Enter the following menus: Body Electrical / Pre-Collision 2 / Utility / Front Beam Axis Adjustment.

(5) According to the display on the Techstream, press "Next".

(6) Perform the adjustment according to the display on the Techstream.

NOTICE:

If an error code is displayed, perform troubleshooting according to the following table, then perform the adjustment again.

(7) Press the "Exit" button to finish front beam axis adjustment.

(d) Front Beam Axis Misalignment Reading:

NOTICE:

• Close all of the doors.
• Ensure that nobody enters the adjustment area during the adjustment.
• Do not move or shake the vehicle during adjustment (do not get in or out of the vehicle).
• During the procedure, do not enter the adjustment area.
• Do not turn off the Techstream or ignition switch.

(1) Enter the following menus: Body Electrical / Pre-Collision 2 / Utility / Front Beam Axis Misalignment Reading.

(2) According to the display on the Techstream, press "Next".

(3) Perform the adjustment according to the display on the Techstream.

Specified Condition:

NOTICE:

If the result is not as specified, perform beam axis adjustment again.

(e) Front Beam Axis Offset Reading:

(1) Enter the following menus: Body Electrical / Pre-Collision 2 / Utility / Front Beam Axis Offset Reading.

(2) According to the display on the Techstream, press "Next".

(3) Perform the adjustment according to the display on the Techstream.

Specified Condition:

NOTICE:

If the result is not as specified, perform beam axis adjustment again.

(4) Turn the ignition switch off.

(5) Disconnect the Techstream from the DLC3.
