5D2-54 TRANSFER CASE - TOD
DIAGNOSTIC TROUBLE CODE (DTC) 1736
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.
Step
Was the TOD Diagnostic System Check performed?
1
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
3 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?
