TT10: Internal HVIL connection fault
HVIL
The HVIL is short for “High Voltage Interlock Loop”.
HVIL is a hardware signal, and its purpose is to
protect the user. When the system is fully installed
and connected, the HVIL internal loop is closed which
results in a short circuit between its two input pins.
The HVIL signal is used to open the high-voltage
battery contactor when its internal loop is opened
during product maintenance or repair (e.g. removal of
MCU cover or disconnection of motor sensor cable)
thereby protecting the user.
Description
The Troubleshooting Tree 10 indicates that the HVIL
lines have an internal fault. The possible causes of
this error are listed below, in order of likelihood:
1. The HVIL parameters were not configured
correctly. The user must access the parameters
through TM4 ODIN and set them.
2. The MCU phase cables, sensor cables, or DC
input cables are not inserted properly. The
system must be turned OFF before the cables
can be inserted and locked in again.
3. The motor sensor cable may not be fully inserted
with connector locking mechanism engaged in
both sides (MCU and motor). The system must
be turned OFF and then the cables must be
locked by the locking mechanism engaged on
both sides (MCU and motor).
4. The motor is defective.
5. The MCU is defective.
Note : Refer to the TM4 Product Operation and
maintenance guide for more details.
Note : Refer to the TM4 MCU installation guide for
more details on installation and deinstallation
procedure including safety warning considerations
Note : Refer to the TM4 motor installation guide for
more details on installation and deinstallation
procedure including safety warning considerations
To correctly diagnose the faulty system, connect the
Diagnostic Tool (see «Diagnostics» section for test
equipment
and descriptions) and follow the
troubleshooting tree procedure below.
See “Safety Warnings” and “Troubleshooting Tips”
sections for general guidelines on system diagnostics.
