5D2-52  TRANSFER CASE - TOD

DIAGNOSTIC TROUBLE CODE (DTC) 1735

Speed Sensor Referance Voltage Low

Circuit Description

The transfer case control unit (TOD) provides reference
voltage to front and rear propeller-shaft speed sensor.

Conditions for Setting the DTC

If the system is in high range the TOD sets the EMC
touch off level based on a vehicle speed of 0 and wheel
slip control is suspended.

•

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

Diagnostic Aids

•

Check for short to ground or open circuit.

Test Description

The number(s) below refer to step(s) on the diagnostic
table.

2. This step, along with step 3, checks the voltage

supply condition.

5. This step checks the continuity of ground line.

7. This step checks the speed sensors.

Action

Was the TOD Diagnostic System Check performed?

1. Disconnect white 7-pin connector, for propeller shaft

speed sensor and clutch coil, located under the body.

2. Turn the ignition switch to ON.

3. Measure the voltage between following terminals of

male white 7-pin connector:

Terminal D/E and terminal B/G
Is measured value within the specified range?

Measure the resistance between terminal A8 and

terminals B8 of transfer case control unit (TOD).
Is measured value within the specified range?

1. Turn the ignition switch to OFF.
2. Check two connectors of the TOD and white 7-pin

connector.

3. Repair any damaged pins, connector or wires.

4. Reconnect all the connectors and make sure it is

seated properly.

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

6. Turn the ignition switch to ON.
7. Request DTC

Is the DTC still current?

1. Turn the ignition switch to OFF.
2. Disconnect two connectors of the TOD and white

7-pin connector under the body.

3. Measure the resistance between following terminals:

•

A8 (TOD) and 1/2 (7-pin connector)

•

B8 (TOD) and 6/7 (7-pin connector)

Is the resistance equal to specified value?

4. Measure the resistance between A8 and B8 of TOD

connector and ground

Is the resistance equal to specified value?

Repair any open or short to ground circuit.

Is the repair complete?

5D2-54  TRANSFER CASE - TOD

Speed Sensor Reference Voltage High

Circuit Description

The transfer case control unit (TOD) provides reference
voltage to front and rear propeller-shaft speed sensor.

Conditions for Setting the DTC

If the reference voltage supply line is shorted to
battery, then the 4WD CHECK indicator will illuminated
and the diagnostic trouble code (DTC) will stored to
the TOD.

•

If the system is in high range the TOD sets the
EMC touch off level based on a vehicle speed of 0
and wheel slip control is suspended.

•

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