NOTE
1433-05 Scraper Parking
Brake Solenoid Current
Always inspect harness connectors that are involved in the circuit. Poor
Below Normal
connections can often be the cause of a problem in an electrical circuit.
Verify that all connections in the circuit are clean and secure and that all
connections are in good condition. If a problem with the connection is
found, correct the problem and verify that this malfunction or diagnostic
code is active before performing this procedure.
Perform open or short-circuit test at each harness connection to identify
the correct harness to replace.
Tag all wiring harnesses to aid in installation.
Perform this test only if condition is active.
