CONSULT-II DIAGNOSTIC TEST MODE FUNCTION
NOTE:

When any initialization is performed, all ID previously registered will be erased and all NATS ignition keys
must be registered again.

The engine cannot be started with an unregistered key. In this case, the system will show “DIFFERENCE
OF KEY” or “LOCK MODE” as a self-diagnostic result on the CONSULT-II screen.

REMOVAL
1. Remove instrument driver lower panel. Refer to IP-10, "INSTRUMENT PANEL ASSEMBLY" .
2. Remove steering column assembly. Refer to PS-13, "
STEERING COLUMN" .
3. Disconnect stop lamp switch and brake switch connector.
4. Remove stop lamp switch and brake switch from brake pedal assembly.
5. Disconnect brake pedal stroke sensor connector.(With pre-crash seat belt)
CAUTION:
Brake pedal stroke sensor is not detachable. Do not detach it.
6. Remove snap pin and clevis pin from clevis of brake booster.
7. Remove brake pedal assembly mounting nuts. Pull brake booster toward engine room to the extent that
does not deform brake tube.
8. Remove brake booster clevis from input rod.
9. Remove mounting bolt and then remove brake pedal assembly from vehicle.
INSPECTION AFTER REMOVAL

Check the items below. If any is found, replace brake pedal
assembly.
–Check brake pedal upper rivet for deformation.
–Make sure that joint length “L” of sub-bracket and sliding plate is
4 mm (0.16 in) or more.
–Check brake pedal for bend, damage, and cracks on the welded
parts.

Check clevis pin and plastic stopper for damage and deforma-
tion. If any is found, replace clevis pin.
INSTALLATION
Installation is the reverse order of removal. Tightening torques for brake pedal assembly mounting nuts and
bolt are referred to BR-7, "
COMPONENTS" . Tightening torque for lock nut is referred to BR-18, "COMPO-
NENTS" .

Adjust brake pedal height after installing brake pedal assembly to vehicle. Refer to BR-6, "Inspection and
Adjustment" .

BRAKE TUBE AND HOSE
Revision: 2007 April2007 M35/M45
CAUTION:

All brake hoses and tubes must be free from excessive bending, twisting and pulling.

Make sure that there is no interference with other parts when turning steering both clockwise and
counterclockwise.

Brake tubes and hoses are an important safety part. Always disassemble the parts and retighten
their fittings, if a brake fluid leak is detected. Replace applicable part with a new one, if damaged
part is detected.

Be careful not to splash brake fluid on painted areas; it may cause paint damage. If brake fluid is
splashed on painted areas, wash it away with water immediately.

Cover the open end of brake tubes and hoses when disconnecting to prevent entrance of dirt.

Refill with new brake fluid “DOT 3”.

Never reuse drained brake fluid.

INSTALLATION
1. Assemble the union bolt and copper washer to the brake hose.
CAUTION:
Do not reuse copper washer.
2. Install brake hose by aligning with the protrusion on brake caliper assembly, and tighten union bolt to the
specified torque. Refer to BR-11, "
Hydraulic Circuit" .
3. Connect brake hose to brake tube, partially tighten flare nut by hand as much as possible, then secure it
to the bracket with lock plate.
4. Using a flare nut torque wrench, tighten flare nut to the specified torque. Refer to BR-11, "
