1. Inspect the control solenoid valve assembly connectors and pins (1, 2, 11, 13) for the following conditions:
   • Damage
   • Bent pins
   • Debris
   • Broken retaining tab
   • Contamination
2. Ensure no metallic debris is inside the connectors near the terminal pins.
3. Inspect the control solenoid valve assembly solenoid leads (3) for contamination or metallic debris.
4. Inspect the 4 control solenoid valve assembly filter plate retaining tabs (12) for cracks and ensure proper tension when filter plate is attached.
