iii. Select the module you want to view. In this
example, Module 1 will be used.
iv. In the Controller Module Diagnostics
window, look for:
0.00 voltage: May indicate a disconnected
lead or missing VSL fuse.
0.01 voltage: Could be normal, if voltage is
being read over a battery interconnect
(battery bar or strap)
Unusually high or double voltage: May
indicate switched leads.
Negative voltage: Usually indicates switched
leads.
NOTE: When two leads which are close together
have “Out of Range” readings, it is likely that
they have been switched, particularly if other
nearby readings are normal. It is especially likely
in this case because the reading between them is
negative.
8 Fix the error.
Go to the hardware and check it. In this case, we have looked for incorrectly connected leads. To
solve the problem we switched the leads back to their proper connections.
9
Recheck the
readings.
a. In the Controller Module Diagnostics window,
reselect the module and wait for new readings.
The very low (0.01 volt) reading is normal if the
unit reflects a voltage reading over an
interconnect or battery strap/bar.
b. Click Close when done.
