Component Inspection
INSPECT MIRROR MOTOR OPERATIONw/o Driving position memory:
a. Connect the positive (+) lead from the battery to terminal 6 and negative (-) lead to terminal 5, then check that the mirror turns to left side.
b. Reverse the polarity and check that the mirror turns to right side.
c. Connect the positive (+) lead from the battery to terminal 4 and negative (-) lead to terminal 5, then check that the mirror turns upward.
d. Reverse the polarity and check that the mirror turns downward.
INSPECT MIRROR MOTOR OPERATION
w/ Driving position memory:
a. Connect the positive (+) lead from the battery to terminal 11 and negative (-) lead to terminal 12, then check that the mirror turns to left side.
b. Reverse the polarity and check that the mirror turns to right side.
c. Connect the positive (+) lead from the battery to terminal 11 and negative (-) lead to terminal 10, then check that the mirror turns upward.
d. Reverse the polarity and check that the mirror turns downward.
INSPECT MIRROR POSITION SENSORS
HINT: Strip off the vinyl tape of the connector and remove terminals 6, 7, 10, 11, 12, 13 and 14 from the connector housing.
a. Connect a series of three 1.5 V dry cell batteries.
b. Connect the positive (+) lead from the dry cell batteries to terminal 7 and the negative (-) lead to terminal 6.
c. Connect the positive (+) lead from the voltmeter to terminal 13 and the negative (-) lead to terminal 6.
d. Apply battery positive voltage to terminals 10 and 11, then check that the voltage gradually changes according to the table while the mirror moves between the uppermost position and lowermost position.
If voltage value is not as specified, replace the motor assembly.
e. Disconnect the 4 leads of the battery and voltmeter.
f. Connect the positive (+) lead from the voltmeter to terminal 14 and negative (-) lead to terminal 6.
g. Apply battery positive voltage to terminals 11 and 12, then inspect that the voltage gradually changes according to the table below while the mirror moves between the left-most position and right-most position.
If voltage value is not as specified, replace the motor assembly.
INSPECT ELECTRICAL RETRACT MOTOR CONTINUITY
a. Connect the positive (+) lead from the battery to terminal 2 and negative (-) lead to terminal 1, check that the no continuity exists in folding position.
b. Reverse the polarity, check that no continuity exists in driving position.
If operation is not as specified, replace the mirror assembly.
INSPECT ELECTRICAL RETRACT MOTOR CONTINUITY
At drive position:
a. Connect the positive (+) lead from the battery to terminal 2 and negative (-) lead to terminal 1, check that continuity exists in folding position.
b. Reverse the polarity, check that no continuity exists in driving position.
If operation is not as specified, replace the mirror assembly.
INSPECT ELECTRICAL RETRACT MOTOR CONTINUITY
Between drive position and retract position:
a. Connect the positive (+) lead from the battery to terminal 2 and negative (-) lead to terminal 1, check that continuity exists in folding position.
b. Reverse the polarity, check that no continuity exists in driving position.
If operation is not as specified, replace the mirror assembly.
INSPECT MIRROR MOTOR OPERATION
a. Connect the positive (+) lead from the battery to terminal 2 and negative (-) lead to terminal 1.
b. Check that the motor turns (moves to folding position).
NOTE: These tests must be performed quickly (within 5 - 10 seconds) to prevent the coil from burning out.
c. Connect the positive (+) lead from the battery to terminal 1 and negative (-) lead to terminal 2.
d. Check that the motor turns (moves to driving position).
NOTE: These tests must be performed quickly (within 5 - 10 seconds)to prevent the coil from burning out.
If operation is not as specified, replace the mirror assembly.
