ELECTRICAL TROUBLESHOOTING
Connect the meter to each end of the resistor
that was removed from the ISO solenoid and
measure its resistance.
The meter reading should be 250 Ohms
(+/-10%). If it is not 250 ohms (+/-10%),
then replace the resistor. Stop trouble
shooting here and repair the problem.
When the repair is completed,
completely retest the vehicle before
lowering the drive wheels to the ground.
Stop, do not continue. If you reached this point without a solution, then you may have an
unanticipated problem or have made an error during testing. It is important to review the
trouble shooting steps that have led to this point. The tests may need to be repeated.
