This procedure measures the change of battery
resistance. Test requires DCA hookup only.
Run confidence test. Warm up engine to
operating temperature. Turn off all electrical
Possible Error Messages:

Cffset not performed.
VTM does not detect battery voltage.
VTM cannot use data received.
No first-peak information was detected
by the VTM.

An error message
Observe displayed value (milliohms/seconds).
The limit is 50 milliohms per battery pair.
A lower number is better than a higher one.
If .22.214.171.124 is displayed, the battery resis-
tance change value is beyond the range of
the VTM and cannot be measured with the
If E013 is displayed, check battery
connections and correct as necessary.
Repeat Step 6. If EO13 persists after 3
tests, VTM cannot perform test.
