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. Test Relay Control.
1. Connect MSD (WP 0006). Select
Trans/Chassis 120M ECM and
verify 0444-03 is active.
2. Turn ignition switch to the OFF
position.
3. Disconnect harness connector
FA-C21 (WP 0009, Figure 124)
from transmission ECM J2 (WP
0009, Figure 112) (WP 0137).
4. Disconnect harness connector
FA-C41 (WP 0009, Figure 21)
from circuit breaker box harness
connector R-C5 (WP 0009, Figure
22) (WP 0234).
