Diagnostic Aids

NOTE: After each service or repair procedure has been completed, reconnect all components. Clear DTCs and repeat QUICK TEST procedures to ensure all electronic engine control systems are working properly and DTCs are no longer present.

Perform this test when directed by QUICK TEST. Parking Brake Applied (PBA) switch detects when parking brake is applied to enable Power Take-Off (PTO) raised-idle mode.
