5D2-44  TRANSFER CASE - TOD

Front Speed Sensor Voltage Low

Circuit Description

The transfer case control unit (TOD) supplies 5 volts
reference voltage to the front speed sensor and
receives speed signals generated by Hall effect speed
sensor.

Conditions for Setting the DTC

•

The wiring circuit for speed sensor shorted to ground
or opened.

•

The reference voltage circuit is shorted to ground
or opened.

Action Taken When the DTC Sets

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

The TOD then responds as follows:

•

If the system is in high range the TOD uses the
rear speed sensor to determine the EMC touch off
level and wheel slip control is suspended.

•

If the system is in low range, the EMC duty cycle is
set to maximum, independent of vehicle speed, until
the system is shifted out of low range.

•

All electric shift activity is halted until the Ignition
is cycled. If a shift is in progress it will be
completed.

DIAGNOSTIC TROUBLE CODE (DTC) 1731

Was the TOD Diagnostic System Check performed?

1. Turn the ignition switch to OFF.

2. Connect a scan tool to the data link connector (DLC)

and follow the directions given in the scan tool
manual.

3. Turn the ignition switch to ON.
4. Request DTC with scan tool.

Is the DTC 1735 also shown?
1. Turn the ignition switch to OFF.

2. Disconnect 18-pin 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. Measure the resistance between terminals B6 and

terminals of the 7-pin connector.

4. Measure the resistance between terminals B6 and

ground.

Is measured value equal to specified range?
