Error Name/Error Condition/Major Cause/Solution
TD sensor output error: Lower limit (K)
TD sensor output error: Lower limit (C)
TD sensor output error: Lower limit (M)
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.
