Front Disc Brake Pad On-Vehicle InspectionS6RW0D4206002
Inspect pad linings (1) periodically according to
maintenance schedule whenever wheels are removed
(for tire rotation or other reason). Take a look through
each end and inspection hole of caliper and check lining
thickness of outside and inside pads.
If lining is worn and its thickness (“a” in figure) is less
than limit, all pads must be replaced at the same time.
Front brake pad thickness “a” (lining thickness)
Standard: 10 mm (0.39 in.)
Limit: 2 mm (0.08 in.)
Front Disc Brake Pad Removal and InstallationS6RW0D4206003
NOTE
When replacing brake pad, replace it on the
right and left.
Removal
1) Hoist vehicle and remove front wheel.
2) Remove caliper pin bolts (1).
3) Remove caliper (1) from caliper carrier (2).
NOTE
Hang removed caliper (1) with a wire hook (4)
or the like so as to prevent brake hose from
bending and twisting excessively or being
pulled.
Don’t operate brake pedal with brake pads
removed.
4) Remove brake pads (3).
5) Remove brake pad spring (1) as show in figure.
Installation
1) Apply small amount of pad grease “a” (included in
spare parts) to pad spring and set brake pad spring
as shown in figure.
2) Set brake pad springs (1), and install brake pads (2)
and shim (4).
NOTE
Install the brake pad with wear indicator (3) to
the vehicle center side of front right brake
pad.

Step 2. DTC / Freeze Frame Data Check, Record and
Clearance
First, referring to “DTC Check”, check DTC and pending
DTC. If DTC exists, print or write down DTC and freeze
frame data and then clear malfunction DTC(s) by
referring to “DTC Clearance”. Malfunction DTC indicates
malfunction in the system but it is not possible to know
from it whether the malfunction is occurring now or it
occurred in the past and normal condition has been
restored. In order to know that, check symptom in
question according to Step 5 and then recheck DTC
according to Step 6.
Diagnosing a trouble based on the DTC in this step only
or failure to clear the DTC in this step may result in an
faulty diagnosis, trouble diagnosis of a normal circuit or
difficulty in troubleshooting which is otherwise
unnecessary.
Step 3 and 4. Visual Inspection
As a preliminary step, be sure to perform visual check of
the items that support proper function of the engine and
automatic transaxle referring to “Visual Inspection”.
Step 5. Trouble Symptom Confirmation
Check trouble symptoms based on information obtained
in “Step 1. Customer Complaint Analysis: ” and “Step 2.
DTC / Freeze Frame Data Check, Record and
Clearance: ”.
Also, reconfirm DTC according to “DTC Confirmation
Procedure” described in each DTC flow.
Step 6 and 7. Rechecking and Record of DTC and
Freeze Frame Data
Refer to “DTC Check” for checking procedure.Step 8. A/T Basic Check and A/T Symptom
Diagnosis
Perform basic check of A/T according to “A/T Basic
Check” first. When the end of the flow has been reached,
check the parts of the system suspected as a possible
cause referring to “A/T Symptom Diagnosis” and based
on symptoms appearing on the vehicle (symptoms
obtained through steps of customer complaint analysis,
trouble symptom confirmation and/or A/T basic check)
and repair or replace faulty parts, if any.
Step 9. Troubleshooting for DTC
Based on the DTC indicated in Step 6 / 7 and referring to
“applicable DTC flow”, locate the cause of the trouble,
namely in a sensor, switch, wire harness, connector,
actuator, TCM or other part and repair or replace faulty
parts.
Step 10. Check for Intermittent Problem
Check parts where an intermittent trouble is easy to
occur (e.g. wire harness, connector, etc.), referring to
“Intermittent and Poor Connection Inspection in Section
00” and related circuit of DTC recorded in Step 2.
Step 11. Final Confirmation Test
Confirm that the problem symptom has gone and the
vehicle is free from any abnormal conditions. If what has
been repaired is related to the malfunction DTC, clear
the DTC once and check to ensure that no malfunction
DTC is indicated.

Malfunction Indicator Lamp (MIL) CheckS6RW0D5104003
Refer to the same item in “Malfunction Indicator Lamp (MIL) Check in Section 1A” for checking procedure.
Transmission Warning Light Check (Non-Euro-OBD model)S6RW0D5104053
1) Turn ignition switch ON.
2) Check that transmission warning light lights for about 2 – 4 sec. and then goes OFF.
If anything faulty is found, advance “Transmission Warning Light Circuit Check – Light Does Not Come “ON” at
Ignition Switch ON (Non-Euro-OBD Model)” or “Transmission Warning Light Circuit Check – Light Remains “ON”
at Ignition Switch ON (Non-Euro-OBD Model)”.
DTC TableS6RW0D5104004
NOTE
• There are two types of OBD system depending on the vehicle specification.For identification, refer
to “Precaution on On-Board Diagnostic (OBD) System in Section 1A”.
• For non-Euro-OBD model, some of DTC No. with (*) mark in the following table can not be detected
by TCM depending on vehicle specification and local regulation.
• With the CAN communication OBD generic scan tool, DTC No. with delta ( U) mark in the following
table can not be read.
• A: Driving cycles when MIL lighting and storing DTC in TCM memory for Euro OBD model.
• B: Driving cycles when transmission warning light lighting and storing DTC in TCM memory for non-
Euro-OBD model.
• 1 driving cycle: MIL or transmission warning light lights up when DTC is detected during 1 driving
cycle.
• 2 driving cycles: MIL or transmission warning light lights up when the same DTC is detected also in
the next driving cycle after DTC is detected and stored temporarily in the first driving cycle.
• Driving cycle with (*): MIL or transmission warning light does not light up but TCM detects and
stores DTC.
Also check the following items at engine start, if possible.
• Malfunction indicator lamp ----- Operation “Malfunction Indicator Lamp (MIL) Check”
• Transmission warning light ----- Operation “Transmission Warning Light Check (Non-Euro-
OBD model)”
• Charge warning lamp ----- Operation “Generator Symptom Diagnosis in Section 1J”
• Engine oil pressure warning lamp ----- Operation “Oil Pressure Warning Light Symptom Diagnosis in
Section 9C”
• Engine coolant temp. meter ----- Operation “Engine Coolant Temperature (ECT) Meter
