How to Troubleshoot
•
When the MIL (Malfunction Indicator Light) comes
ON or blinks, or when a problem occurs during oper-
ation, perform troubleshooting according to the fol-
lowing procedures.
•
For diagnostic troubleshooting, use a tapered tester
probe that fits the I.D. of the connecter terminal of a
commercially available digital circuit tester.
Connect the tester probe to the digital circuit tester,
taking care not to apply excessive force to the con-
necter terminal.
•
Refer to the base shop manual for the diagnostic
troubleshooting information that is not covered in
this supplement.
1. Turn the ignition switch ON and check that the MIL
comes ON.
2. If the MIL comes ON or blinks, check the DTC
(Diagnostic Trouble Code) using the HDS (Dr. H or
Pocket Tester).
3. Perform troubleshooting according to the "DTC-to-
Symptom Troubleshooting Chart" (page 5-3).
Check each connector for secure connection and
the wire harness for any abnormality, and connect
or repair as necessary before troubleshooting.
4. After troubleshooting, repair as necessary and per-
form the post-troubleshooting steps (page 5-2).
DTC (Diagnostic Trouble Code) Check
Using HDS
If the DLC is 2 pole connector, the HDS can not be
used for DTC check.
1. Remove the engine cover and remove the electric
part cover.
2. Remove the red 4P connector and connect the HDS
(Dr. H or Pocket Tester) to the DLC (data link con-
nector).
3. Turn the ignition switch ON.
4. Check the DTC and freeze data shown on the HDS
(Dr. H or Pocket Tester).
See the operation manual of the HDS (Dr. H or
Pocket Tester) for the detailed information about
