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 con-
nection 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 Implement ECM.
1. Connect MSD (WP 0006). Select
Implement 120M and verify 0168-
01 is active.
2. Perform charging system tests
Perform corrective action as directed
in charging system tests (WP 0040).
Proceed to step 3.
3. Using the MSD (WP 0006), select 0168-01 Code Remains Active -
Implement 120M and verify 0168- Proceed to Test Step 2.
01 is not active.
0168-01 Code Not Active -
Troubleshooting complete.
Test Step 2. Test Battery (+) Supply
Circuits.
1. Turn ignition switch and battery
disconnect switch to the OFF
position (TM 5-3805-293-10).
2. Disconnect harness connector
FA-C20 (WP 0009, Figure 113)
from transmission ECM J1 (WP
0009, Figure 112) (WP 0137).
3. Turn battery disconnect and igni-
tion switch to the ON position (TM
5-3805-293-10).
