ON-VEHICLE INSPECTION
1. INSPECT ELECTRIC PARKING BRAKE ACTUATOR ASSEMBLY
HINT: Using the intelligent tester or Techstream to perform the Active Tests allows relays, VSVs and actuators and other items to be operated
without removing any parts. This non-intrusive functional inspection can be very useful because intermittent operation may be discovered before
parts or wiring is disturbed. Performing Active Tests early in troubleshooting is one way to save diagnostic time. Data List information can be
displayed while performing Active Tests.
