5D2-56 TRANSFER CASE - TOD
Motor Output Open / Shorted to Battery
Circuit Description
The transfer case control unit (TOD) sends current to
move the shift motor upon the position of the 4H/4L
switch.
Conditions for Setting the DTC
If the TOD detects a shift motor fault continuously for
one seconds, the 4WD CHECK indicator will illuminated
and the diagnostic trouble code (DTC) will stored to
the TOD.
•
Motor HI-LO circuits are shorted to battery.
•
Motor LO-HI circuits are shorted to battery.
•
Motor HI-LO circuits are shorted to motor LO-HI
circuits.
•
Motor circuits are open.
DIAGNOSTIC TROUBLE CODE (DTC) 1741

Was the TOD Diagnostic System Check performed?
1. Turn the ignition switch to OFF.
2. Disconnect two connectors of the transfer case control
unit (TOD) and 7-pin connector under the body.
3. Inspect the terminals for damage or improper connection.
4. Repair any damaged pins or terminals on the wiring
harness and TOD.
5. Reconnect the connectors and make sure it is seated
properly.
6. Connect a scan tool to the data link connector (DLC).
7. Turn the ignition ON.
8. Request the DTC with scan tool.
Is the DTC still current?
1. Disconnect the black 7-pin connector for shift motor
under the body.
2. Turn the ignition switch to ON.
3. Position shift lever to N (neutral).
4. Connect the voltmeter between terminal 7 of female
7-pin connector and ground.
5. Measure the voltage while switching the 4L/4H switch
from 4H to 4L.
Is the voltage within the specified value?
6. Connect the voltmeter between terminal 6 of female
7-pin connector and ground.
7. Measure the voltage while switching the 4L/4H switch
from 4L to 4H.
Is the voltage within the specified value?
