Charging system indicator stays on, no DTCs set
WARNING: This page is about a different car, the 2011 Honda Insight and 2010 Honda Insight. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
If the 12V battery voltage is too low to operate the starter motor, the charging system indicator may come on.
- Turn the ignition switch to ON (II).
- Check the DC-DC CONVERTER TEMPERATURE in the DATA LIST with the HDS.
Is there 201-257 °F (94-125 °C) indicated?
YES -The system is OK at this time. The charging system indicator will go off when the DC-DC converter temperature decreases. If the temperature does not decrease even though time has passed, replace the DC-DC converter (see DC-DC CONVERTER REMOVAL/INSTALLATION ).
NO -go to step 3.
- Do the gauge self-diagnostic function (see
SELF-DIAGNOSTIC FUNCTION
).
Does the charging system indicator flash?
YES -go to step 4.
NO -Substitute a known-good gauge control module, and recheck. If the charging system indicator circuit is OK, replace the original gauge control module.
- Turn the ignition switch to LOCK (0).
- Turn the battery module switch OFF (see DISCONNECTING THE MOTOR POWER CABLE CONNECTOR FROM THE MOTOR STATOR ).
- Remove the IPU cover (see IPU COVER REMOVAL/INSTALLATION ).
- Remove the PCU lid, the PCU busplate, and the PCU cover (see MOTOR CONTROL MODULE (MCM) REMOVAL/INSTALLATION ).
- Check the connections at the high voltage terminals (A, B) on the DC-DC converter (C).
