2000 HONDA CIVIC Tachometer

Jlgnition Control Module (lCMl Input Test
NOTE:
. See section 1'l when the malfunction indicator lamp
(MlL) turned on.
. Perform an input test for the ignition control module
(lCM) after finishing the fundamental tests for the
ignition system and the fuel and emissions systems
1. Remove the distributor ignition (Dl) cap, the distrib-
utor ignition (Dl) rotor and the leak cover (TEC).
2. Disconnect the wires from the lCM.
HITACHI:
BLK/YEL
TEC:
Turn the ignition switch ON (ll). Check for voltage
between the BLK/YEL wire and body ground.
There should be battery voltage.
. lf there is no battery voltage, check the BLK/YEL
wire between the under-dash fuse/relay box and
rhe lcM.
. lf there is battery voltage, go to step 4.
Turn the ignition switch ON (ll). Check for voltage
between the wire*r and body ground
There should be battery voltage.
. lfthere is no battery voltage, check:
- the ignition coil.
- the wire*1 between the ignition coil and the
tcM.
. lf there is battery voltage, go to step 5
*1: BLU'wire (HITACHI)
WHT/BLU wire (TEC)
Disconnect the EcM/PCM connector A (32P). Check
for continuity on the YEUGRN wire between the
ECM/PCM and the lCM.
There should be continuity.
Check for continuity on the YEUGRN wire to body
ground.
There should be no continuity.
Check for continuity on the BLUl wire between the
test tachometer connector and the ICM
There should be continuitY.
Check for continuity on the BLUl wire to body ground.
There should be no continuity.
lf all the tests are normal, replace the ICM
