(A.10.A.95.90 - G.30.B.54)
E0024-03 - Hydraulic Reservoir Temp Shorted To High Source
Cause:
The hydraulic reservoir temperature (B18) is shorted to high source.
Possible failure modes:
1. Sensor supply wiring shorted to 12 volts.
2. Controller internal failure (internal regulator failure).
Solution:
1. Enter the InfoView Monitor - "Diagnose info" screen.
Select "Hydraulics" sub menu.
Select "Hydraulic Reservoir Temp" and check voltage range.
The proper voltage range is - 0.5 - 4.9 volts
A. If the voltage reading is above 5.2 volts continue with Step 2.
B. If the voltage reading is within the proper limits, since the shorted wire may not be powered up at this time.
Continue the troubleshooting at Step 4.
2. The voltage reading on the InfoView is high. Disconnect the hydraulic reservoir temperature sensor connector
X103.
A. If the voltage drops to 4.9 - 5.2 volts the short is in the sensor, or sensor wiring. Replace the sensor.
B. If the voltage remains high on InfoView display continue with Step 3.
3. The voltage reading on the InfoView is high. Disconnect the gearbox harness from the main frame harness at
connector X011.
A. If the voltage drops to 4.9 - 5.2 volts the short is in the gearbox harness between connector X011 and
connector X103 wire 446 yellow.
B. If the voltage remains high on InfoView display the short circuit is somewhere between connector X011
and connectorX019 J2-24 on CCM1 in the main frame harness wire 446 yellow.
4. Visually inspect harness and connectors for damage, bent or dislocated pins, corroded terminals or broken
wires.
A. If no damage is found erase fault code and continue operation.
