VERIFY MOTOR WINDING SECTION:
ELECTRICAL SHOCK HAZARD
Failure to follow this warning could result in personal injury
or death or possible equipment damage.
After disconnecting power from the ECM motor, wait at least
five minutes before removing the control section. Internal
capacitors require time to discharge. Minor injury from
electrical shock may result from early contact with live metal
parts.
!
WARNING
Before proceeding to replace a motor control module:
1. Check motor winding section to be sure it is functional.
2. Remove motor control module section and unplug winding
plug. Motor shaft should turn freely, resistance between any
two motor leads should be similar and resistance between
any motor lead and unpainted motor end should exceed
100,000 ohms.
3. Failing any of these tests, entire ECM motor must be re-
placed.
4. Passing all of the tests, motor control module alone can be
replaced.
