General Troubleshooting
Information |
Before
Troubleshooting
1. |
Check applicable fuses in the appropriate
fuse/relay box. |
2. |
Check the battery for damage, state of
charge, and clean and tight connections.
(Refer to the EE group -
"Battery")
• |
Do not quick-charge a battery
unless the battery ground cable has been disconnected,
otherwise you will damage the alternator
diodes. |
• |
Do not attempt to crank the
engine with the battery ground cable loosely connected
or you will severely damage the
wiring. | | |
3. |
Check the alternator belt
tension. |
Handling
Connectors
1. |
Make sure the connectors are clean and have
no loose wire terminals. |
2. |
Make sure multiple cavity connectors are
packed with grease (except watertight
connectors). |
3. |
All connectors have push-down release type
locks (A).

|
4. |
Some connectors have a clip on their side
used to attach them to a mount bracket on the body or on another
component. This clip has a pull type
lock. |
5. |
Some mounted connectors cannot be
disconnected unless you first release the lock and remove the
connector from its mount bracket (A).

|
6. |
Never try to disconnect connectors by
pulling on their wires; pull on the connector halves
instead. |
7. |
Always reinstall plastic
covers.

|
8. |
Before connecting connectors, make sure the
terminals (A) are in place and not bent.

|
9. |
Check for loose retainer (A) and rubber
seals (B).

|
10. |
The backs of some connectors are packed with
grease. Add grease if necessary. If the grease (A) is contaminated,
replace it.

|
11. |
Insert the connector all the way and make
sure it is securely locked. |
12. |
Position wires so that the open end of the
cover faces down.

|
Handling
Wires And Harnesses
1. |
Secure wires and wire harnesses to the frame
with their respective wire ties at the designated
locations. |
2. |
Remove clips carefully; don't damage their
locks (A).

|
3. |
Slip pliers (A) under the clip base and
through the hole at an angle, and then squeeze the expansion tabs to
release the clip.

|
4. |
After installing harness clips, make sure
the harness doesn't interfere with any moving
parts. |
5. |
Keep wire harnesses away from exhaust pipes
and other hot parts, from sharp edges of brackets and holes, and
from exposed screws and bolts. |
6. |
Seat grommets in their grooves properly (A).
Do not leave grommets distorted (B).

|
Testing
And Repairs
1. |
Do not use wires or harnesses with broken
insulation.
Replace them or repair them by wrapping the
break with electrical tape. |
2. |
After installing parts, make sure that no
wires are pinched under them. |
3. |
When using electrical test equipment, follow
the manufacturer's instructions and those described in this
manual. |
4. |
If possible, insert the remover tool from
the wire side (except waterproof connector).

|
5. |
Use a remover tool with a tapered
tip.

Refer to the user's guide in the wiring
repair kit II (Pub. No. : 0K000 003
A05) |
Five-step
Troubleshooting
1. |
Verify the complaint
Turn on all the components in the problem
circuit to verify the customer complaint. Note the symptoms. Do not
begin disassembly or testing until you have narrowed down the
problem area. |
2. |
Analyze the schematic
Look up the schematic for the problem
circuit.
Determine how the circuit is supposed to
work by tracing the current paths from the power feed through the
circuit components to ground. If several circuits fail at the same
time, the fuse or ground is a likely cause.
Based on the symptoms and your understanding
of the circuit operation, identify one or more possible causes of
the problem. |
3. |
Isolate the problem by testing the
circuit.
Make circuit tests to check the diagnosis
you made in step 2. Keep in mind that a logical, simple procedure is
the key to efficient troubleshooting.
Test for the most likely cause of failure
first. Try to make tests at points that are easily
accessible. |
4. |
Fix the problem
Once the specific problem is identified,
make the repair. Be sure to use proper tools and safe
procedures. |
5. |
Make sure the circuit works
Turn on all components in the repaired
circuit in all modes to make sure you've fixed the entire problem.
If the problem was a blown fuse, be sure to test all of the circuits
on the fuse. Make sure no new problems turn up and the original
problem does not recur. |
Battery
Reset
When reconnecting the
battery cable after disconnecting, recharging battery after discharged or
installing the memory fuse located on the driver's side panel after
removing, be sure to reset systems mentioned in the below
table.
In addition, when
replacing or reinstalling their fuses after removing, they should be reset
according to the below table. Please refer to the below table when
servicing.
System
|
Resetting
|
Power
window
|
Whenever the window
cannot be properly closed or opened. Whenever the battery is
discharged or the related fuse is replaced or reinstalled, reset the
power window system according to the procedure below.
1. |
Turn the ignition switch to the ON
position. |
2. |
Push up the power window switch until
the window glass is entirely up and then push up continuously
for about 1 sec. | |
Sunroof
|
Whenever the vehicle
battery is disconnected or discharged, or you use the emergency
handle to operate the sunroof, you have to reset your sunroof system
as follows :
1. |
Turn the ignition key to the ON
position and then close the sunroof completely.
|
2. |
Release the sunroof control lever.
|
3. |
Press and hold the CLOSE button for
more than 10 seconds until the sunroof closed and it has moved
slightly. |
4. |
Release the sunroof control lever.
|
5. |
Press and hold the CLOSE button once
again within 3 seconds until the sunroof does as
follows;
A. |
Tilt → Slide Open → Slide
Close
Then release the
lever. | |
6. |
Reset procedure of sunroof system is
finished. | |
Trip
computer
|
When the battery is
disconnected and reconnected, the set functions of the trip computer
become initialized. So, you need to explain this information
to the customer.
|
Clock
|
When the battery is
disconnected and reconnected, the clock becomes initialized. So, the
clock should be reset. (Refer to the owner's
manual)
|
Audio
|
When the battery is
disconnected and reconnected, the customer's radio stations become
initialized. So, you need to record the customer's radio
preset stations prior to service, and after service, set the
customer's radio preset stations into the audio.
|
Heater &
Air Conditioner
|
When the battery is
disconnected and reconnected, the heater and A/C become initialized.
So, heater and A/C should be
reset.
