TRANSMISSION CONTROL (SHIFT LEVER) TEST - CONTINUED
1.
Start engine (TM 5-3805-290-10).
2.
Place autoshift mode switch in MANUAL position (TM 5-3805-290-10).
N OT E
Highest gear available in REVERSE is third gear.
3.
Disengage parking brake and operate machine in all speeds and in both directions using steering column shift lever.
Implement handle remote F/N/R switch should remain in NEUTRAL position (TM 5-3805-290-10).
4.
Observe transmission operating in all gears and in both directions.
5.
Place steering column shift lever in NEUTRAL and operate machine in all speeds and in both directions using imple-
ment handle remote F/N/R switch.
6.
Observe transmission operating in all gears and in both directions. If transmission does not operate properly and prob-
lem in shift lever is still suspected, proceed to step 8.
N OT E
Refer to Table 3 for the following tests.
7.
Check shift lever signal on status screen.
a.
Disconnect F/N/R switch harness 4-pin connector CN-C50 from shift lever. Connect jumper wire from pin 3 to pin
4 on shifter 4-pin connector (WP 0081 00).
b.
Connect MSD to machine (WP 0006 00).
c.
Turn disconnect switch and engine start switch to ON position (TM 5-3805-290-10).
d.
Select machine ECM and go to status screen 4.
e.
Move shift lever through all possible positions. Observe status of Shift Lever Position on MSD screen.
f.
Expected Results. Status of shift lever position changes properly.
(1)
If status of shift lever position changes properly, diagnostic code does not exist at this time. Proceed to step
12.
(2)
If status on MSD screen is DATA FAULT in all shifter positions, proceed to step 9.
(3)
If status on MSD screen is DATA FAULT in a particular position, proceed to step 10.
8.
Check for power and ground at shifter.
a.
At shifter, connect positive (red) multimeter lead to wire 110 GN. Connect negative (black) multimeter lead to
wire 200 BK.
b.
Measure voltage between two wires.
c.
Expected Results. Voltage is system voltage.
(1)
If result is OK, voltage is system voltage. Proceed to step 10.
(2)
If result is NOT OK, voltage is not system voltage. Wiring to shifter may have failed. Check fuse for wire
110 GN. If fuse is bad, replace fuse. If fuse is good, wiring harness may have failed. Replace wiring har-
ness in question (WP 0169 00 thru WP 0175 00) between fuse and shifter or between shifter and ground.
