Tools Department; FAX

NOTE:  Air temperature must be within 15 38 °C (59 100 °F) during this procedure.
 After this inspection, you must reset the engine control module (ECM)/powertrain control module
(PCM). Otherwise, the ECM/PCM will continue to stop
the fuel injectors from operating.
 The battery must be in good condition and fully charged.
1. Connect the alternator, regulator, battery & starter tester (OTC3131) to the battery as shown.
NOTE: The probe is not used for battery testing.
2. Do the BATTERY TEST. ThebatteryisOK.Gotostep3.
If the display indicates BAD BATTERY, replace
the battery, then retest. If the display indicates
CHARGE & RETEST, charge the battery, then retest. 3. Connect the Honda Diagnostic System (HDS) to the
data link connector (DLC) (see step 2 on page 11-3).
4. Turn the ignition switch to ON (II).
5. Make sure the HDS communicates with the vehicle and the ECM/PCM. If it does not communicate,
troubleshoot the DLC circuit (see page 11-204).
6. Select ALL INJECTORS STOP in the PGM-FI INSPECTION menu with the HDS.
7. Set the parking brake, then with the shift lever in N or P (A/T model) or the clutch pedal pressed (M/T
model), turn the ignition switch to START (III).
The starting system is OK. Go to step 14.
Go to step 8.
8. Turn the ignition switch to LOCK (0).
9. Check the electrical connections at the battery, the negative battery cable to the body, the engine
ground cables, and the starter for looseness and
corrosion. Then try cranking the engine again.
Repairing the loose connection corrected the
problem. The starting system is OK. Go to step 14.
Based on the following symptoms, take the
appropriate action:
 If the starter does not crank the engine at all, go to step 10.
 If the starter cranks the engine erratically or too slowly,gotostep12.
 If the starter does not disengage from the flywheel ring gear (M/T model) or torque
converter ring gear (A/T model) when you
release the key, replace the starter, or remove
and disassemble it, and check for the following:
– Starter solenoid and switch malfunction
– Dirty drive gear or damaged overrunning clutch

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).

14. While holding the drive gear (A), turn the gear shaft (B) counterclockwise. Check that the drive
gear comes out to the other end. If the drive gear
does not move smoothly, replace the gear cover
assembly.
15. While holding the drive gear, turn the gear shaft clockwise. The gear shaft should turn freely. If the
gear shaft does not turn freely, replace the gear
cover assembly.
16. If the drive gear is worn or damaged, replace the overrunning clutch assembly; the gear is not
available separately.
Check the condition of the flywheel ring gear (M/T
model), or the torque converter ring gear (A/T
model) to see if the starter drive gear teeth are
damaged. 17. Install the brush into the brush holder, and set the
armature (A) in the brush holder (B).
NOTE: To seat the new brushes, slip a strip of 500
or 600 sandpaper, with the grit side up, between
the commutator and each brush, and smoothly turn
the armature. The contact surface of the brushes
will be sanded to the same contour as the
commutator.
18. While squeezing a spring (C), insert it in the hole on the brush holder, and push it until it bottoms.
Repeat this for the other three springs (D, E, and F).
19. Install the armature and the brush holder assembly into the housing.
NOTE: Make sure the armature stays in the holder.
