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.
1. Connect MSD (WP 0006). Select
Trans/Chassis 120M ECM and
verify 0041-04 is active.
2. Turn ignition switch and battery
disconnect switch to the OFF
position.
3. Disconnect harness connector
FA-C20 (WP 0009, Figure 113)
from transmission ECM J1 (WP
0137).
4. Disconnect harness connector
AT-C4 (WP 0009, Figure 122)
from right articulation angle posi-
tion sensor (WP 0009, Figure
123) (WP 0257).

Harness connector is located behind cab bulkhead cover on right rear
of cab.
5. Remove rear bulkhead cover
plate (WP 0266).
6. Disconnect harness connector
FA-C23 (WP 0009, Figure 17)
from harness connector P-C71
(WP 0009, Figure 18).
7. Using digital multimeter, test for
