Problem symptom confirmation
Check if what the customer claimed in “Customer 
Questionnaire” is actually found in the vehicle and if that 
symptom is found, whether it  is identified as a failure. 
(This step should be shared with the customer if 
possible.) Check warning lights related to brake system 
referring to “EBD Warning Light (Brake Warning Light) 
Check” and “ABS Warning Light Check”.
DTC check, record and clearance
Perform “DTC Check” proced ure, record it and then 
clear it referring to “DTC Clearance”.
Recheck DTC referring to “DTC Check”.
When DTC which is recorded at DTC check procedure is 
detected again after performi ng DTC clearance, go to 
“Step 4: ABS Check: ” to proceed the diagnosis.
When DTC which is recorded at DTC check procedure is 
not indicated anymore after performing DTC clearance, 
ABS control module does not perform the system 
diagnosis, or temporary abnormality may occur, 
therefore go to “Step 2: Driving Test: ” to proceed the 
diagnosis.
Step 2: Driving Test
Test drive the vehicle at 40 km/h for more than a minute 
and check if any trouble symptom (such as abnormal 
lighting of ABS warn ing light) exists.
If the malfunction DTC is co nfirmed again at ignition 
switch ON, driving test as described is not necessary. 
Proceed to Step 3.
Step 3: DTC Check
Recheck DTC referring to “DTC Check”.
Step 4: ABS Check
According to ABS Check for  the DTC confirmation in 
Step 3, locate the cause of the trouble, namely in a 
sensor, switch, wire harness, connector, actuator 
assembly or other part and repair or replace faulty parts.
Step 5: Brakes Diagnosis
Check the parts or system suspected as a possible 
cause referring to “Brakes Symptom Diagnosis in 
Section 4A” and based on symptoms appearing on the 
vehicle (symptom obtained through Steps 1 and 2 and 
repair or replace faulty parts, if any).
Step 6: Check for Intermittent Problem
Check parts where an intermittent trouble is easy to 
occur (e.g., wire harness, con nector, etc.), referring to 
“Intermittent and Poor Connection Inspection in Section 
00” and related circuit of trouble code recorded in Step 1 
to 3.
Step 7: Final Confirmation Test
Confirm that the problem symptom has gone and the 
ABS is free from any abnormal conditions. If what has 
been repaired is related to  the malfunction DTC, clear 
the DTC once referring to “DTC Clearance” and perform 
test driving and confirm that no DTC is indicated.ABS Warning Light CheckS7RS0B4504002
1) Turn ignition switch ON.
2) Check that ABS warning  light (1) comes ON for 
about 2 seconds and then goes off.
If any faulty condition is  found, advance to “ABS 
Warning Light Does Not Come ON at Ignition Switch 
ON” or “ABS Warning Light Comes ON Steady”.
EBD Warning Light (Brake Warning Light) 
Check 
S7RS0B4504003
NOTE
Perform this check on a level place.
 
1) Turn ignition switch ON with parking brake applied.
2) Check that EBD warning lig ht (brake warning light) 
(1) is turned ON.
3) Release parking brake with ignition switch ON and  check that EBD warning lig ht (brake warning light) 
goes off.
If it doesn’t go off, go to “EBD Warning Light (Brake 
Warning Light) Comes ON Steady”.

Steering Column Removal and InstallationS7RS0B6206006
CAUTION! 
Once the steering column is removed from 
the vehicle, the column is extremely 
susceptible to damage.
• Dropping the column assembly on its end could collapse the steering shaft or loosen 
the plastic shear pins which maintain 
column length.
• Leaning on the column assembly could  cause it to bend or deform.
Any of the damage could impair the column’s 
collapsible design.
Steering column mounting nuts should not 
be loosened with steering shaft joint upper 
side bolt tightened as this could cause 
damage to shaft joint bearing.
 
NOTE
When servicing steering column or any 
column-mounted component, remove 
steering wheel. But when removing steering 
column simply to gain access to instrument 
panel components, leave steering wheel 
installed on steering column.
 
Removal
WARNING! 
Never rest a steering column assembly on 
the steering wheel with the air bag (inflator) 
module face down and column vertical. 
Otherwise, personal  injury may result.
 
1) Disconnect negative (–) cable at battery.
2) Disable air bag system. Re fer to “Disabling Air Bag 
System in Section 8B”.
3) Remove steering wheel and contact coil cable  assembly referring to “S teering Wheel Removal and 
Installation” and “Contact Coil Cable Assembly 
Removal and Installation”.
4) Detach lighting switch and wiper switch from steering  column.
5) Remove immobilizer cont rol module from steering 
column, referring to “Immo bilizer Control Module 
(ICM) Removal and Installation in Section 10C”.
6) Remove steering column hole cover.
7) Remove steering joint cover.
8) Make alignment marks (4) on lower shaft (1) and  shaft joint of steering column (2) and lower shaft (1) 
and pinion shaft (3) for a guide during reinstallation.
9) Remove lower shaf t joint bolts (5).
10) Remove steering lower shaft (1).
11) Remove steering column mounting nuts (1).
12) Remove steering column from vehicle.

Installation
CAUTION! 
After tightening steering column mounting 
nuts, shaft joint bolts should be tightened.
Wrong tightening order could cause a 
damage to shaft joint.
 
1) Be sure that front wheels are in straight.
2) Install steering column assembly to lower and upper brackets. Tighten steering column lower nuts (1) first 
and then upper nuts (2) to specifications as given 
below.
Tightening torque
Steering column nut (a):   14 N·m (1.4 kgf-m, 10.5 
lb-ft)
NOTE
After installing tilt steering column, make 
sure that steering column moves backwards 
and forwards smoothly and stops when tilt 
lever is fixed.
 
3) Align flat part “A” of stee ring lower shaft (1) with bolt 
hole “B” of shaft joint (2) of column as shown. Then 
insert lower shaft into shaf t joint of steering column 
with matching marks (4).
4) Insert lower shaft (1) into pinion shaft (3) with  matching marks (4).
5) Tighten joint bolt (pinion shaft side) (6) to specified  torque first and then joint bolt (steering column side) 
(5) to specified torque.
CAUTION! 
After tightening column nuts, tighten steering 
shaft upper joint bolt.  Otherwise shaft joint 
bearing is damaged.
 
Tightening torque
Steering shaft joint bolt (a):  25 N·m (2.5 kgf-m, 
18.5 lb-ft) 6) Install steering joint cover.
7) Install immobilizer cont
rol module from steering 
column, referring to “Immo bilizer Control Module 
(ICM) Removal and Installation in Section 10C”.
8) Install lighting switch and wiper switch to steering  column.
9) Install contact coil cable assembly and steering  wheel referring to “Conta ct Coil Cable Assembly
