General Troubleshooting
Information |
Before Troubleshooting
1. |
Check applicable fuses in the appropriate
fuse/relay box. |
2. |
Using the battery checker (MCR-570 KIT), 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 probe with a tapered tip.
Refer to the user's guide in the wiring repair
kit (Pub No. : TRK 015.)

|
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 on 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
|
Auto
up/down window
|
Whenever the
battery is disconnected, discharged or the related fuse is replaced
or reinstalled, reset the Auto up/down window system according to
the procedure below.
1. |
Turn the ignition switch to the ON
position. |
2. |
Pull up the power window switch in order
that the window can close completely, and then keep pulling up
the power switch for about 1
second. | |
Panoramaroof
|
Whenever the
battery is disconnected, discharged or the related fuse is replaced
or reinstalled, the panoramaroof system must be reset according to
the procedure below.
1. |
Turn the ignition key to the ON position
and then close the panoramaroof
completely. |
2. |
Release the panoramaroof control
lever. |
3. |
Press and hold the CLOSE button for more
than 10 seconds until the sunroof has moved
slightly. |
4. |
Release the panoramaroof control
lever. |
5. |
Press and hold the CLOSE button once
again until the sunroof do as
follows. |
•
|
Tilt → Slide Open → Slide
Close
Then, release the
lever. |
6. |
Reset procedure of panorama 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
|
▶ With audio
off
1. |
Press the [SETUP] button until the clock
of the display blinks. |
2. |
Set the clock by turning the [ENTER]
knob and press it. | ▶ With audio on
1. |
Press the [SETUP] button until the clock
of the display blinks. |
2. |

knob and press it. | |
Audio
|
When the battery
is disconnected and reconnected, the customer's radio stations
become initialized. So, you need to record the customer's radio
stations prior to service, and after service, set the customer's
radio stations into the audio.
