INSPECTION SERVICE POINTS FOR A BLOWN
FUSE
M1001013800067
Remove the blown fuse and measure the resistance between
the load side of the blown fuse and the ground. Close the
switches of all circuits which are connected to this fuse. If the
resistance is almost 0
at this time, there is a short some-
where between these switches and the load. If the resistance is
not 0
, there is no short at the present time, but a momentary
short has probably caused the fuse to blow.
The main causes of a short circuit are the following.
Harness being clamped by the vehicle body
Damage to the outer casing of the harness due to wear or
heat
Water getting into the connector or circuitry
Human error (mistakenly shorting a circuit, etc).
HOW TO TREAT CURRENT TROUBLEM1001014000020
1. Make a note of the diagnostic trouble code, and erase it.
2. Check the trouble symptom again.
3. Check for diagnostic trouble codes again.
4. If a diagnostic trouble code is set, follow the applicable
Diagnostic Trouble Code Chart.
5. If no diagnostic trouble code is set, refer to "How to Cope
with Intermittent Malfunction P.00-14."
HOW TO TREAT PAST TROUBLEM1001014100050
1. Establish from the customer whether a fuse or connector
has been replaced or disconnected.
2. If yes, erase the diagnostic trouble code, and then check
that no diagnostic code is reset. If no diagnostic trouble
code is reset, the diagnosis is complete.
3. If no, follow the applicable Diagnostic Trouble Code Chart.
Then check the wiring harness and connector, and refer to
"How to Cope with Intermittent Malfunction P.00-14."

STEP 8. Check the harness wire between stoplamp switch
connector C-30 terminal 2 and fuse number 11 at the relay
box at engine compartment for damage.
Q: Is the harness wire in good condition?
YES : Go to Step 9.
NO : Repair the damaged harness wire. Then go to Step
22.
STEP 9. Check the fuse number 11 at the relay box at
engine compartment.
Q: Is the fuse in good condition?
YES : Go to Step 10.
NO : Check the stoplamp system harness and replace the
fuse. Then go to Step 22.
