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. Test Sensor and Cir-
cuits.
1. Connect MSD (WP 0006). Select
0674-02 Code Active - Proceed to
Trans/Chassis 120M and verify
step 2.
0674-02 is active.
0674-02 Code Not Active - Trouble-
shooting complete.
2. Turn ignition switch and battery
disconnect switch to the OFF
position (TM 5-3805-293-10).
3. Disconnect transmission sensor
wiring harness connector V-C2
(WP 0009, Figure 157) from
transmission input speed sensor
1 (WP 0009, Figure 158) (WP
0150).
4. Using a digital multimeter, mea-

ohms and 1,800 ohms.
5. Install a jumper wire between har-
ness connector V-C2 (WP 0009,
Figure 157) terminal 1 and termi-
nal 2.
6. Disconnect harness connector
FA-C20 (WP 0009, Figure 113)
from transmission ECM J1 (WP
0009, Figure 112).
