Diagnostics
Measure the value of the resistance in the servo motor between L GN/YL and PU/YL. See "Specifications". Proceed to step 2.
If the resistance value is incorrect see step 3. If the resistance value is correct see step 4.
Replace the servo motor.
Disconnect the connectors from the servo motor and measure the voltage between the connectors PU/YL and L GN/YL. See "Specifications". Proceed to step 5.
If the voltage value is incorrect see step 6. If the voltage value is correct see step 7.
Check the harness and repair the harness between the connector and the control unit. Also, check the system power source.
Fit the servo motor and measure the voltage between terminals 1 - 27 of the control unit. Measure the value at the recirculation position. See "Specifications". Proceed to step 8.
If the voltage values are incorrect see step 9. If the voltage values are correct see step 10.
Check the harness and repair the harness between the connector and the control unit.
Replace the control unit.Specifications
