3.
Connect a 6 Volt power source to terminals 1 - 2 and verify the operation of the servo. By alternating the polarity of the power source, the servo
will retract or extend.
Caution: Do not apply a voltage higher than 6 Volts. If a higher voltage is used, damage to the ISC servo can result.
HARNESS TEST
1. Disconnect the ECU and ISC connectors. Using an Ohmmeter, check for continuity (short) to ground, between the ECU harness connector terminals
58 and 59 and the ISC connector terminals 1 and 2.
Continuity: Should Not Exist.
2. Using an Ohmmeter, check for continuity between the ECU harness connector terminals 58 and 59 and their corresponding ISC connector terminals
1 and 2.
Continuity: Should Exist.
If any of the previous tests produce unsatisfactory results, the harness will need to be repaired or replaced. Once repairs have been completed, road
test the vehicle to confirm that the repair has corrected the problem.
If the same problem reoccurs, it is possible that there is an intermittent failure of the component or the ECU. Check for looseness at all harness
junctions and test for an intermittent failure.
