TEST 1.3:
Test the voltage at pin #6 on the 12-pin logic card
connector.
If the voltage is low, then skip ahead to test #1.4.
If the voltage is high, then check the wire to the
High/Low switch and the High/Low switch for
open circuits.
NOTE: The High/Low switch is optional and
the vehicle may not have this option.
If the vehicle is not equipped with
option then there is a jumper bypass
installed in place of the switch in the
dash. Check the jumper to be sure it
is still connected.
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.
TEST 1.4:
Test the voltage at pin #5 on the 12-pin logic card
connector.
If the voltage is low, then skip ahead to test #1.5.
If the voltage is high, then:
•
Check the seat switch for open contacts.
•
Check that the seat switch is engaging the seat
correctly.
•
Check the wire from the pin 5 to the seat switch
for open circuits.
•
Check the wire from the seat switch to B- for
open circuits.
If all of the above is in working order, then the logic
card may have failed.
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
Stop, do not continue. Reaching this point indicates a failure in the Sevcon power unit or
an error was made during testing. Confirm all previous tests were performed correctly
before replacing the Sevcon power unit.
