General Troubleshooting Information |
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")
|
3. |
Check the alternator belt tension. |
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. |
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). |
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.) |
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. |
Description |
System | Resetting | ||||||||||||||
Auto up/down 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.
| ||||||||||||||
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.
| ||||||||||||||
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 | Whenever the battery terminals or related fuses are disconnected, you must reset the time. When the ignition switch is in the ACC or ON position, the clock buttons operate as follows : ? Hour : Pressing the H button will advance the time displayed by one hour. ? Minute : Pressing the M button will advance the time displayed by one minute. ? To change the 24 hour format to the 12 hours format (if equipped), while pressing the “H” button, press the “M” button for 3 seconds or more. For example, if the “H” and “M” buttons are pressed for more than 3 seconds while the time is 22:15, the display will change to 10:15. | ||||||||||||||
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. |
