10. Make sure the shift lever is in N or P (A/T model) orneutral (M/T model), then disconnect the engine
wire harness 1P connector (A). Connect a jumper
wire from the battery positive terminal to the
starter subharness 1P connector (B).
Go to step 11.
Check the starter subharness. If the wire is OK,
remove the starter (see page 4-10), then repair or
replace (see page 4-13) it as necessary. 11. Check the following items in the order listed until
you find the problem circuit:
NOTE: After the open circuit or high resistance in
the circuit is found and repaired, go to step 14.
 Check for an open or short in the YEL wire and connectors between the driver’s under-dash
fuse/relay box and the ignition switch.
 Check for an open or short in the RED wire and connectors between the under-dash fuse/relay
box and the engine wire harness 1P connector.
 Check for an open or short in the ORN wire and connectors between the under-dash fuse/relay
box and the clutch interlock switch (M/T model).
 Check for an open or short in the ORN wire, BLU/ WHT wire and connectors between the under-
dash fuse/relay box and the transmission range
switch (A/T model).
 Check for poor ground at G401 (M/T model) or G101 (A/T model).
 Check for a faulty ignition switch (see page 22-72).
 Check for a faulty clutch interlock switch (M/T model) (see page 4-8).
 Check for a faulty transmission range switch (A/T model) (see page 14-265).
 Check for a faulty starter cut relay (see page 22-70).

1. Check the No. 7 (20 A) fuse in the under-hood fuse/relay box and the No. 36 (10 A) fuse in the under-
dash fuse/relay box.
Reinstall the fuse(s), then go to step 2.
Replace the fuse(s), and recheck. If the fuse
continues to blow, locate and repair the short in the
circuit between the under-hood fuse/relay box and
the radiator fan motor, or between the under-dash
fuse/relay box connector terminal G12, the under-
hood fuse/relay box and the engine control module
(ECM)/powertrain control module (PCM).
2. Remove the radiator fan relay and the fan control relay from the under-hood fuse/relay box, and test
them (see page 22-70).
Go to step 3.
Replace the radiator fan relay and/or fan
control relay.
3. Measure the voltage between the radiator fan relay 4P socket terminal No. 1 and body ground.
Go to step 4.
Replace the under-hood fuse/relay box. 4. Connect fan control relay 5P socket terminals No. 1
andNo.2withajumperwire.
5. Connect radiator fan relay 4P socket terminals No. 1 and No. 2 with a jumper wire.
Go to step 10.
