PEAK VOLTAGE INSPECTION
PROCEDURE
• Check all system connection before inspection. If
the system is disconnected, incorrect peak volt-
age might be measured.
• Use recommended digital multimeter or com-
mercially available digital multimeter with an
impedance of 10 MΩ/DCV minimum.
Connect the peak voltage adaptor to the digital mul-

CIRCUIT INSPECTION
INSPECTION AT PCM CONNECTOR
• Always clean around and keep any foreign mate-
rial away from the PCM connector before discon-
necting it.
• A faulty Honda S Matic System is often related to
poorly connected or corroded connections.
Check those connections before proceeding.
• In testing at PCM connector (wire side) terminal,
always use the test probe. Insert the test probe
into the connector terminal, then attach the digi-
tal multimeter probe to the test probe.
