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 0590-09
is Active.
1. Connect MSD (WP 0006). Select 0590-09 Code Active - Proceed to
Implement 120M and verify 0590- Test Step 2.
09 is active.
0590-09 Code Not Active -
Troubleshooting complete.
Test Step 2. Test Voltage Supply
Circuit.
1. Turn ignition switch and battery
disconnect switch to the OFF
position (TM 5-3805-293-10).
2. Disconnect harness connector
FA-C17 (WP 0009, Figure 14)
from engine ECM J1 (WP 0067).
3. Turn battery disconnect switch
and ignition switch to the ON posi-
tion (TM 5-3805-293-10).
4. Using digital multimeter, test for
