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
