Troubleshooting
SC No. Level Error Name/Error Condition/Major Cause/Solution
SC362-01 D TD sensor output error: Lower limit (K)
SC362-02 D TD sensor output error: Lower limit (C)
SC362-03 D TD sensor output error: Lower limit (M)
SC362-04 D TD sensor output error: Lower limit (Y)
TD sensor output: Vt (SP3-210-001 - 004) < output lower limit
error threshold (SP3-211-004) is continuously below the lower
limit occurrence threshold value (SP3-211-005)
TD sensor connector missing/dropout
1. TD sensor connector missing check
2. Check whether there is any error in the TD sensor harness
(disconnection, etc.)
3. If the sensor is defective, replace the development unit.
SC No. Level Error Name/Error Condition/Major Cause/Solution
SC370-01 D TM (ID) sensor calibration error (F)
SC370-02 D TM (ID) sensor calibration error (C)
SC370-03 D TM (ID) sensor calibration error (R)
Regular reflection optical output voltage of the Front or Center or
Rear TM (ID) sensor: Vsg_reg cannot be adjusted to within
target range.
Upper limit (SP3-320-013: initial value 4.5V)
Lower limit (SP3-320-014: initial value 3.5V)
§ TM (ID) sensor connector missing/ connection fault
§ TM (ID) sensor detection window dirt
§ TM (ID) sensor malfunction
§ Undulation in the ITB, or belt slippage
