2000 HONDA CIVIC Switch

Chocking th€ Diagnostic Trouble Code (DTCI
with the Servico Check Conneqtor and Sp€cialTool
When the PCM senses an abnormality in the input or output systems, the @ indicator light in the gauge assembly will blink
When the Service Check Connector (locat€d under the dash on the passengsr side) is connected with the special tool as
shown, the E indicator light will blink the Diagnostic Trouble Code (DTC) when the ignition switch is turned ON (ll).
When the E indicator light has been reported on, connect the Service Check Connector with the special too'.
Then turn ON (ll) the ignition switch and obssrve the E indicator tight.

Codes 1 through 9 are indicated by individual short blinks, Codes 10 and above are indicat€d by a sories of long and short
blinks. One long blink equals 1O short blinks. Add the long and short blinks together to determine th€ code. After deter-
mining the code, refer to the electrical system Symptom-to Component Chart on pages 1+52 and 1+53 for'96 - 98 mod-
els, and 14-54 and 14-55 for the '99 - 00 models.

PCM Reset Procedure
1. Turn the ignition switch off.
2. Remove the BACK UP fuse (7.5 A) from the under-hood fuse/relay box for '10 seconds to reset the PCM'
NOTE:
. Disconnecting the BACK UP fuse also cancels the radio preset stations and clock setting Make note of the radio
presets before removing the luse so you can reset them
. in" gCfU memory can also be cleared by using the OBD ll Scan Tool or Honda PGM Tester'
Final Procedure
NOTE: This procedure must be done after any troubleshooting.
1. Turn the ignition switch OFF.
2. Reset the PcM.
3. Disconnect the oBD ll scan Tool or Honda PGM Tester from the Data Link connector, or remove the special tool from
the Service Check Connector.
4. Turn the ignition switch ON (ll), and set the radio presets and clock setting'
