Disassembly and AssemblyINFOID:0000000003532828
DISASSEMBLY
1. Remove mounting bolt from upper joint, then remove upper joint from steering column assembly.
2. Remove ignition switch tamper resistant self-shear screws with a drill or other suitable tool.
ASSEMBLY
Assembly is in the reverse order of disassembly.
• Install new tamper resistant self-shear screws.
NOTE:
Any time the ignition switch has been removed and installed, the
keys must be re-registered in the BCM. Refer to CONSULT-II opera-
tion manual IVIS/NVIS.
INSPECTION AFTER ASSEMBLY
When the steering wheel does not turn smoothly, check the steering column as follows:
1. Check the column bearings for damage or unevenness. Lubricate with recommended multi-purpose
grease. Replace the steering column as an assembly, if necessary.
2. Check the column tube for deformation or breakage. Replace the steering column as an assembly, if nec-
essary.

1. Turn off all loads on the vehicle electrical system. Clean or repair
as necessary.
2. Visually inspect the battery, battery terminals and cable ends
with ignition switch in “OFF” position.
NOTE:
The contact surface between the battery terminals, cable ends
and tester leads must be clean for a valid test. A poor connec-
tion will prevent testing and a “CHECK CONNECTION” mes-
sage will appear during the test procedures. If this occurs, clean
the battery post and terminals, reconnect them and restart the
test.
3. Connect the red tester lead clamp to the positive battery termi-
nal, and the black to the negative terminal.
4. The tester will turn on automatically. Using the arrow keys,
select “IN-VEHICLE” on the tester and then press the “ENTER”
key.
5. Locate the battery type and rating stamped or written on the top
case of the battery to be tested.
NOTE:
The battery rating will be either of the following:
•CCA: Cold Cranking Amps (490 CCA, 550 CCA, etc.)
•JIS: Japanese Industrial Standard.
When using the Battery Tester use the CCA rating only.
• The tester requires the CCA rating for the battery be entered
exactly as it is written or stamped on the battery.
• (U.S. market) Refer to the latest "Battery Testing" Technical
Service Bulletin (TSB) for a chart which contains these ratings
listed by vehicle.
• You must not use the JIS rating.
6. Using the arrow and “ENTER” keys alternately, select the battery type and rating.
NOTE:
The tester lists five choices; CCA, JIS, IEC, DIN, and EN. Only use CCA or JIS.
7. Press “ENTER” to begin the test. Diagnosis results are dis-
played on the tester. Refer to "DIAGNOSTIC RESULT ITEM
CHART".

• The settings (ON/OFF) of the automatic sliding seat (entry/exiting operation) at entry/exit can be changed as
desired, using the display unit in the center of the instrument panel. The set content is transmitted by CAN
communication, from display control unit to driver seat control unit.

NOTE:
• Disconnecting the battery erases the stored memory.
• After connecting the battery, insert the key into the ignition cylinder and turn the front door switch LH ON (open)→OFF (close)→ON
(open), the entry/exiting function becomes possible.
• After Exiting operation is carried out, return operation can be operated.
NOTE:
During automatic operation, if the ignition switch is turned ON→START, the automatic operation is suspended. When the ignition switch
returns to ON, it resumes.
FA I L - S A F E M O D E
When any manual and automatic operations are not performed, if any motor operations of seats or pedals are
detected for T2 or more, status is judged “Output error”.
CANCEL OF FAIL-SAFE MODE
The mode is cancelled when the A/T selector lever is shifted to P position from any other position.
NOTE:
The front seat LH position and pedal adjustment functions (see the following table) operate simultaneously in
the order of priority.
*: In conjunction with sliding the seat, the door mirrors are positioned.Function Description
Memory operation The front seat LH, steering wheel, pedals (accelerator, brake) and door mirrors move
to the stored driving position by pushing seat memory switch (1 or 2).
Entry/exit-
ing functionExiting operation At exit, the seat moves backward and the steering wheel raises. (Exiting position)
Entry operationAt entry, the seat and steering wheel return from exiting position to the previous driving
position before the exiting operation.
Keyfob interlock operationPerform memory operation, turnout operation and return operation by pressing keyfob
unlock button.
Auto operation temporary stop
conditions.When ignition switch is turned to START during seat memory switch operation and return
operation, seat memory switch operation and return operation is stopped.
Auto operation stop conditions.• When the vehicle speed becomes 7 km/h (4 MPH) or higher (memory switch operation
and entry operation).
• When the setting switch, seat memory switch 1, or 2 are pressed.
• When A/T selector lever is in any position other than P.
• When the door mirror remote control switch is operated (when ignition switch turned to
ON).
• When power seat switch turned ON.
• When pedal adjusting switch turned ON.
• When front seat sliding entry/exiting setting is OFF (entry/exiting operation).
