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 0070-03 is active.
2. Turn ignition switch and battery
disconnect switch to the OFF
position.
3. Disconnect harness connector

from transmission ECM J2 (WP
0009, Figure 112).
4. Position parking brake switch in
the ON position (TM 5-3805-293-
