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).

12. Do the STARTING TEST with the alternator, regulator battery & starter tester.
NOTE: The probe is used for starter testing.
Go to step 13.
Replace the starter, or remove and
disassemble it, and check for these problems:
 Draginthestarterarmature
 Short in the armature winding
 Excessive drag in the engine
 Open circuit in starter armature commutator segments
 Excessively worn starter brushes
 Open circuit in the starter brushes
 Dirty or damaged helical splines or drive gear
 Faulty overrunning clutch
13. Remove the starter, and inspect its drive gear and the flywheel ring gear (M/T model) or the torque
converter ring gear (A/T model) for damage.
Replace any damaged parts.
14. Select ECM/PCM reset (see page 11-4) in the PGM- FI INSPECTION menu to cancel ALL INJECTORS
STOP with the HDS. 1. Disconnect the clutch interlock switch 2P connector
(A).
2. Remove the clutch interlock switch (B).
3. Check for continuity between the terminals accordingtothetable.
 If the continuity is not as specified, replace the clutch interlock switch (see page 12-8).
 If OK, install the clutch interlock switch, and adjust the pedal height (see page 12-8).

1. Remove the starter (see page 4-10).
2. Make the connections for this test using the thickest
(gauge) wire possible (preferably the same gauge
as used on the vehicle).
NOTE: To avoid damaging the starter, never leave
the battery connected for more than 10 seconds.
3. Connect the battery as shown, and check for continuity between the B terminal and the starter
body. If there is continuity, it is working properly.
4. Disconnect the battery from the starter body, and check for continuity between the B terminal and the
starter body. If there is no continuity, it is working
properly. 5. Firmly clamp the starter in a vise.
6. Connect the starter to the battery as shown, and
confirm that the motor runs.
7. If the electric current meets the specification when the battery voltage is at 11.5 V, the starter is
working properly.
