II. Engine Control Module (ECM) Reset Procedure

Either of the following actions, will reset the ECM.

• Using the OBD II scan tool or Honda PGM Tester to clear the ECM's memory.

NOTE: See the OBD II scan tool or Honda PGM Tester user's manuals for specific operating instructions.

• Turn the ignition switch OFF. Remove the CLOCK (7.5 A) fuse from the under-hood fuse/relay box for 10 seconds.

NOTE: If the CLOCK (7.5 A) fuse is removed when the ignition switch is in the ON (II) position, the MIL will come

on and the ECM will store a DTC.

FUSE/RELAY BOX
CLOCK

(7.5 A) FUSE

III. Final Procedure (this procedure must be done after any troubleshooting)

1. Remove the SCS Service Connector if it is connected. If the SCS service connector is connected and there are no

DTCs stored in the ECM, the MIL will stay on when the ignition switch is turned on.

2. Do the ECM Reset Procedure.

3. Turn the ignition switch OFF.

4. Disconnect the OBD II scan tool or Honda PGM Tester from the Data Link Connector (16P).

IV. Known-Good ECM Substitution

The ECM is part of the immobilizer system. If you substitute a known-good ECM, the ECM will have a different immo-

bilizer code. In order for the engine to start, you must rewrite the immobilizer code with the Honda PGM Tester.ProCarManuals.com

Be careful not ot bend the edge of the roof opening.

The roof is made of aluminum alloy. Take care not to dent or scratch the roof. If there is a minor dent or scratch on the roof, repair
the roof with putty (refer to the body repair manual).

When replacing the component parts of the roof, place the roof on an appropriate pad to prevent damage.
NOTE:

Have an assistant help remove the roof.

When the roof is stored on the engine cover, lock the roof cover securely.

When installing the roof, secure it by turning both roof side lock handles. Make sure they are locked securely.
