Toyota Tacoma 2015-2018 Service Manual: On-vehicle Inspection
ON-VEHICLE INSPECTION
PROCEDURE
1. INSPECT BRAKE PEDAL HEIGHT
(a) Check the brake pedal height.
Pedal height from dash panel:
|
Type |
Pedal Height |
|---|---|
|
Automatic transmission |
164.4 to 174.4 mm (6.473 to 6.866 in.) |
|
Manual transmission |
160.5 to 170.5 mm (6.319 to 6.712 in.) |
NOTICE:
Do not adjust the pedal height. Doing so by changing the push rod length will structurally change the pedal ratio.
If the pedal height is incorrect, adjust the rod operating adapter length.
(b) Adjust the rod operating adapter length.
(1) Remove the clip and clevis pin.
(2) Loosen the clevis lock nut.
(3) Adjust the rod operating adapter length by turning the pedal push rod clevis.
Rod operating adapter length A:
for Hydraulic brake booster
214 to 224 mm (8.425 to 8.818 in.)
for Vacuum brake booster
213 to 223 mm (8.386 to 8.780 in.)
(4) Tighten the clevis lock nut.
Torque:
26 N·m {260 kgf·cm, 19 ft·lbf}
(5) Install the clip and clevis pin.
- If the pedal height is incorrect even when the rod operating adapter is adjusted, check that there is no damage in the brake pedal, brake pedal lever, brake pedal bracket or dash panel.
- Even if there is damage, there is no problem if the reserve distance is within the standard value.
- If necessary, replace the parts.
2. INSPECT AND ADJUST STOP LIGHT SWITCH ASSEMBLY
HINT:
If the pedal height is incorrect, check and adjust the stop light switch.
(a) Disconnect the stop light switch connector from the stop light switch.
(b) Turn the stop light switch counterclockwise, and remove the stop light switch.
|
(c) Insert the stop light switch until the body comes into contact with the cushion. NOTICE:
|
|
|
(d) Make a quarter turn clockwise to install the stop light switch. NOTICE: The turning torque for installing the stop light switch: Torque: 1.5 N·m {15 kgf·cm, 13 in·lbf} or less |
|
(e) Check the protrusion of the rod.
Protrusion of the rod:
0.5 to 2.6 mm (0.020 to 0.102 in.)
(f) Connect the stop light switch connector to the stop light switch.
3. INSPECT PEDAL FREE PLAY
(a) Stop the engine and depress the brake pedal several times until there is no more vacuum left in the booster.
(b) Push in the pedal until the beginning of the resistance is felt. Measure the distance as shown.
Pedal free play:
1 to 6 mm (0.04 to 0.24 in.)
4. INSPECT PEDAL RESERVE DISTANCE
(a) Release the parking brake pedal.
With the engine running, depress the pedal and measure the pedal reserve distance as shown.
Pedal reserve distance from asphalt sheet at 490 N (50 kgf, 110.2 lbf):
More than 55 mm (2.17 in.)
If incorrect, troubleshoot the brake system.

Vehicle Information Not Obtained (C1A02)
DESCRIPTION
When a new millimeter wave radar sensor assembly is installed, it receives vehicle
specification information (destination, steering wheel position, 2WD or 4WD, etc.)
from the main body ECU (multiplex network body ECU) and stores the information.
DTC C1A02 is stored when the millime ...

Brake Switch "A" Circuit (P0571)
DESCRIPTION
Detection condition 1:
When the brake pedal is depressed, the stop light switch assembly outputs
a signal to the ECM. When the ECM receives the signal, it cancels control
of vehicle speed by the dynamic radar cruise control system. The fail-safe
function operates to ...
