Signal too low. Intermittent fault

Intermittent fault
Check the connector for the damper motor and control module connector A (30-pin). Check for contact resistance and oxidation.
Check the signal cable between climate control module terminal #A19 and damper motor terminal #4. Check for an intermittent open-circuit. Check for an intermittent short-circuit to ground.
Check the power supply cable between climate control module terminal #A18 and damper motor terminal #1. Check for an open-circuit. Check for a short-circuit to ground.

Fault-tracing information
If the fault is intermittent, do not verify fault-tracing if the fault does not recur.
It is possible to view the information again, or leave fault-tracing for this diagnostic trouble code (DTC).
