Hyundai Elantra MD/UD: General Information
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")
|
| 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.

|
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.
