Always inspect harness connectors that are involved in circuit.
Poor connections can often be the cause of an electrical circuit
problem. Verify that all connections in circuit are clean and
secure, and connections are in good condition. If a problem with
connection is found, correct problem and verify diagnostic code
is active before performing this procedure.
Tag wiring harnesses to aid installation.
Perform this test only if condition is active.
1. Turn ignition switch and bat-
tery disconnect switch to OFF
position (TM 5-2410-240-10).
2. Disconnect harness connec-
tor C-C57 (WP 0018, Figure

perature sensor.
3. Install jumper wire between
terminal 1 and terminal 2.
