Remedy: • Check the TD sensor connection. • Check the home position sensor for abnormality. • Replace the TD sensor if it is abnormal.
Code: SC370-01
Description: ID sensor calibration error (F). The voltage reading during process control for Vsg_reg was not within the correct range (4.0 ± 0.5 V). Details: Vsg_reg is the voltage reading of the light reflected directly from the bare surface of the ITB. ID sensor calibration adjusts the LED current so that Vsg_reg becomes 4.0 ± 0.5 V. Adjustment flow: 1. Vsg_reg confirmation If Vsg_reg is smaller than 0.5V, SC371-0X is issued and process control ends. 2. ID sensor calibration Fluctuates the LED current and measures Vsg_reg. 3. LED current upper limit check OK: Proceeds to Vsg upper/lower limit check NG: SC372-0X is issued; proceeds to Vsg upper/lower limit check 4. Vsg upper/lower limit check OK: Process control continued NG: SC370-0X is issued and process control ends.
Causes: • ITB deformed, out of position or damaged
Remedy: • Check the ITB. • Fix the ITB if it is deformed, out of position, etc.
Code: SC370-02
Description: ID sensor calibration error (C). The voltage reading during process control for Vsg_reg was not within the correct range (4.0 ± 0.5 V). Details: Vsg_reg is the voltage reading of the light reflected directly from the bare surface of the ITB. ID sensor calibration adjusts the LED current so that Vsg_reg becomes 4.0 ± 0.5 V. Adjustment flow: 1. Vsg_reg confirmation If Vsg_reg is smaller than 0.5V, SC371-0X is issued and process control ends. 2. ID sensor calibration Fluctuates the LED current and measures Vsg_reg. 3. LED current upper limit check OK: Proceeds to Vsg upper/lower limit check NG: SC372-0X is issued; proceeds to Vsg upper/lower limit check 4. Vsg upper/lower limit check OK: Process control continued NG: SC370-0X is issued and process control ends.
Causes: • ITB deformed, out of position or damaged
Remedy: • Check the ITB. • Fix the ITB if it is deformed, out of position, etc.
Code: SC370-03
Description: ID sensor calibration error (R). The voltage reading during process control for Vsg_reg was not within the correct range (4.0 ± 0.5 V). Details: Vsg_reg is the voltage reading of the light reflected directly from the bare surface of the ITB. ID sensor calibration adjusts the LED current so that Vsg_reg becomes 4.0 ± 0.5 V. Adjustment flow: 1. Vsg_reg confirmation If Vsg_reg is smaller than 0.5V, SC371-0X is issued and process control ends. 2. ID sensor calibration Fluctuates the LED current and measures Vsg_reg. 3. LED current upper limit check OK: Proceeds to Vsg upper/lower limit check NG: SC372-0X is issued; proceeds to Vsg upper/lower limit check 4. Vsg upper/lower limit check OK: Process control continued NG: SC370-0X is issued and process control ends.
Causes: • ITB deformed, out of position or damaged
Remedy: • Check the ITB. • Fix the ITB if it is deformed, out of position, etc.
Code: SC371-01
Description: ID sensor output error (F). The ID sensor voltage reading of the light reflected directly (Vsg_reg) is below 0.5 V.
Causes: • ID sensor connector disconnected/loose connection • ID sensor defective
Remedy: • Check if the ID sensor connector is connected. Connect it if disconnected. • Replace the ID sensor if defective.
