Check the ICM

NOTE:If the malfunction indicator lamp (MIL) comes on, refer to the Diagnostic
Trouble Code (DTC) troubleshooting Index; refer to the '98-02 Accord Service
Manual.

Perform an input test for the ignition control module (ICM) after finishing
the fundamental tests for the ignition system and the fuel and emissions
systems.

1. Disconnect the 3P connector from the distributor.

2. Turn the ignition switch ON (II). Check for voltage between the No. 2
terminal and body ground. There should be battery voltage.

+ If there is no battery voltage, check:

- ignition coil.
- BLK/YEL wire between the ICM and ignition coil.

+ If there is battery voltage, go to step 3.

3. Turn the ignition switch ON (II). Check for voltage between the No. 3
terminal and body ground. There should be battery voltage.

+ If there is no battery voltage, check:

- ignition coil.
- BLU wire between the ICM and ignition coil.

+ If there is battery voltage, go to step 4.

4. Disconnect PCM connector B (25P) and check for continuity on the No. 1
terminal between the ICM connector terminal No. 1 (YEL/GRN) and PCM connector
terminal B13. There should be continuity.

5. Check for continuity on the No. 1 terminal to body ground. There should be
no continuity. If there is continuity (short to ground), the ICM is probably
damaged.

6. Reconnect PCM connector B (25P) and the distributor 3P connector.

+ If all the tests are normal, replace the ICM.
