Diagnostic Trouble Code (Dtc) 1733 - SSANGYONG Rexton Y200 Manual

5D2-48 TRANSFER CASE - TOD

DIAGNOSTIC TROUBLE CODE (DTC) 1733

Rear Speed Sensor Voltage Low
Circuit Description
The transfer case control unit (TOD) supplies 5 volts
reference voltage to the front and rear 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
front 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.
Step
Was the TOD Diagnostic System Check performed?
1
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
2
manual.
3. Turn the ignition switch to ON.
4. Request DTC with scan tool.
Is the DTC 1736 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 17 of TOD
3
and terminals in female white 7-pin connector.
Is measured value equal to specified range?
4. Measure the resistance between terminals B17 of
TOD and ground.
Is measured value equal to specified range?
Action
Diagnostic Aids
•
Check for short to ground or open circuit.
