E0013-05-Cleaning Fan RPM Sensor Line Disconnected
(K.62.B.95.52 - G.30.B.50)
E0013-05 - Cleaning Fan RPM Sensor Line Disconnected
Cause:
The cleaning fan RPM sensor (B-16) circuit is disconnected.
Possible failure modes:
1. Sensor supply or ground wiring is disconnected.
2. Controller internal failure (internal regulator failure).
Solution:
1. Enter the InfoView Monitor - "Diagnose info" screen.
Select "Cleaning" sub menu.
Select "Cleaning Fan RPM sensor" and check voltage range.
The proper voltage sensor blocked by ferrous metal - 5.6 - 7.3 volts
The proper voltage sensor unblocked by ferrous metal - 0.5 - 5.6 volts
A. If there is an open in the supply/ground wiring the voltage will read 7.3 - 9.0 volts.
B. If the voltage reading is high indicating an open continue with Step 2.
C. If the voltage reading is within the proper limits. Continue the troubleshooting at Step 6.
2. The voltage reading on the InfoView is 7.3 - 9.0 volts. Disconnect the cleaning fan RPM sensor connector
X089. Install a jumper wire between pins A and B on connector X089.
A. If the voltage drops to 0 - 0.5 volts the open is in the sensor, or sensor wiring. Replace the sensor.
B. If the voltage remains out of range on InfoView display continue with Step 3.
3. The voltage reading on the InfoView is above 7.3 - 9.0 volts. Remove the jumper wire from connector X089.
Use a multimeter to check for continuity between pin A on connector X089 and chassis ground.
A. If no continuity is found continue with Step 4.
B. If continuity is found continue with Step 5.
4. Use a multimeter to check for continuity between pin 16 on connector X023 and chassis ground.
A. If no continuity is found, there is an open in wire 723, or 501 blue between connectors X023 and connector
X020 J3-18 on CCM1. Locate and repair the open circuit.
B. If continuity is found the open is between connector X023 and X089 wire 723 or 718 blue in lower frame
harness.
5. The voltage reading on the InfoView is 7.3 - 9.0 volts. Disconnect the connector X023. Install a jumper wire
between pins 7 and 16 on connector X023.
A. If the voltage drops to 0 - 0.5 volts the open is between connector X023 and X089 on wire 404 yellow.
Locate and repair the open.
B. If the voltage remains at 7.3 - 9.0 volts on InfoView display the open is between connector X023 and
connector X020 J3-13 wire 404 yellow. Locate and repair the open.
6. 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.
