5D2-40  TRANSFER CASE - TOD

Electromagnetic Clutch Open / Short to
Battery

Circuit Description

To control the distribution of the torque to front propeller
shaft, the transfer case control unit (TOD) sends a
signal to the electromagnetic clutch (EMC). Then the
clutch disc is compressed or released by the EMC.

Conditions for Setting the DTC

Even the TOD send signal for controlling the EMC, it
receives uncontrolled propeller shaft speed signal.

•

The wiring circuit to EMC opened.

•

The wiring circuit is shorted to battery.

Action Taken When the DTC Sets

The TOD will illuminates 4WD CHECK indicator and
DTC is stored in TOD.

DIAGNOSTIC TROUBLE CODE (DTC) 1721

Diagnostic Aids

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 white 7-pin connector, for
propeller shaft speed sensor and clutch coil, located
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. Turn the ignition switch to OFF.

2. Disconnect the 12-pin connector from transfer case

control unit (TOD).

3. Turn the ignition switch to ON.
4. Connect a digital voltmeter between each of the

following TOD connector terminal and ground.
