BAlTERY RESISTANCE CHANGE TEST #75
Description:
This procedure measures the change of battery
resistance. Test requires DCA hookup only.
Pre-Test Procedures:
Run confidence test. Warm up engine to
operating temperature. Turn off all electrical
accessories.
Typical Applications:
Possible Error Messages:
Evaluate batteries in Cl engines with VTM
powered from batteries of vehicle being tested.

Transducer not connected.
Cffset not performed.
VTM does not detect battery voltage.
VTM cannot use data received.
No first-peak information was detected
by the VTM.
VTM cannot calculate result because
current is over current probe’s range.

Disconnect fuel solenoid wire 54A to prevent
starting.
Make sure all vehicle accessories are off.
Set TEST SELECT switches to 75.

Press and release TEST button.
When GO appears on display, engage starter
for 2 seconds or until one of the following
appears on the display: OFF
.9.9.9.9
A number
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.
E021
NOTES:
If .9.9.9.9 is displayed, the battery resis-
tance change value is beyond the range of
the VTM and cannot be measured with the
VTM.
If E013 is displayed, check battery
connections and correct as necessary.
Repeat Step 6. If EO13 persists after 3
tests, VTM cannot perform test.
