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 for Shorted Rear

1. Connect MSD (WP 0006). Select
Trans/chassis 120M and verify
1404-03 is active.
2. Turn ignition switch and battery
disconnect switch to the OFF
position.
3. Disconnect the transmission har-
ness connector T-C6 (WP 0009,

clutch modulating valve 4 (WP
0009, Figure 175) (WP 0155).
4. Disconnect the rear chassis wir-
ing harness connector FA-C20
(WP 0009, Figure 113) from trans-
