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.
In rare case, “CHAIN OF ECM-IMMU” might be stored as a self-diagnostic result during key registration
procedure, even if the system is not malfunctioning.
HOW TO READ SELF-DIAGNOSTIC RESULTS
System Diagnosis mode DescriptionReference
page
NATS V5.0C/U INTIALIZATIONPerform registration again after repair, part replacement, and
additional key ID registration.
CAUTION:
“Control Unit Initialization” is activated only after per-
forming “Release steering lock”.Refer to the
Technical Bul-
letin.

BRAKE PEDAL
Revision: 2006 January2006 M35/M45
WITH PRE-CRASH SEAT BELT
NOTE:
Clevis pin can be installed from both left and right.
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 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.
Replace brake pedal assembly if any non-standard condition is
detected.

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.
Removal and Installation of Front Brake Tube and Brake Hose NFS000OZ
REMOVAL
1. Drain brake fluid. Refer to BR-10, "Drain and Refill" .
2. Disconnect brake hose from brake tube, using a flare nut wrench.
3. Remove union bolt and remove brake hose from caliper assem-
bly.
4. Remove lock plate and remove brake hose from vehicle.
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-12, "
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-12, "
Hydraulic Cir-
cuit" .
5. Refill brake fluid and bleed air. Refer to BR-11, "
