P1477 - Variable inlet manifold motor 2.: Open circuit or No signal.
P1477 - Variable inlet manifold motor 2.: Short circuit to ground.

Possible causes:
1. Connector MS43 ECM C606, Variable intake motor bank 2 C973, Engine fusebox C578.
2. Open circuit C606/49 (BG) - C973/1 (BG).
3. Short circuit C606/49 (BG) - Ground.
4. Variable intake manifold motor bank 2.
5. MS43 ECM.

1. Connector MS43 ECM C606, Variable intake motor bank 2 C973, Engine fusebox C578.
CONNECTOR
Check for connector not correctly latched, backed out pins, damaged pins, corroded pins

2. Open circuit C606/49 (BG) - C973/1 (BG).
OPEN_CIRCUIT
Check resistance > 1M Ohms.

3. Short circuit C606/49 (BG) - Ground.
SHORT_CIRCUIT
Check resistance < 5.0 Ohms.

4. Variable intake manifold motor bank 2.
