Always inspect the harness connectorsthat are involved in the circuit.
Poor 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 a
connection is found, correct the problem and verify that this diagnostic
code is active before performing this procedure.
Perform open or short circuit test ateach harness connection to identify
correct harness to replace.
Perform this test only if condition is active.
Test Step 1. Verify if Code 0168-01
is Active in Trans/Chassis ECM.
1. Connect MSD (WP 0006). Select
Trans/Chassis 120M and verify
0168-01 is active.
2. Perform charging system tests

position (TM 5-3805-293-10).
2. Disconnect harness connector
