The following procedures will troubleshoot SID 60.
Section 23.2.1
060 05 – Fan Open Circuit
Perform the following steps to troubleshoot a fan open circuit fault.
- Bridge pins 2 and 3 on the fan electrical connector. See Figure
"Pin Locations on Fan Electrical Connector"
.
1. Pin 1
3. Pin 3
2. Pin 2
4. Fan Connector

- If code 060 06 is active, repair or replace the fan control clutch. Erase fault code memory.
- If code 060 06 is not active, go to step 2 .
- Measure resistance between pins 43 and 12 on the 55-pin connector. See Figure
"55-Pin Wiring Harness Connector"
and see Figure
"Location of Fan Control Wires "
.

- If resistance is less than 3 Ω, contact Detroit Diesel Technical Service.
- If resistance is greater than 3 Ω, repair open circuit in wire 43 or wire 12 on the 55-pin connector. Erase fault code memory.
Section 23.2.2
060 06 – Fan Short to Ground
Perform the following steps to troubleshoot a fan short to ground fault:
- Unplug cooling fan.
- If new fault 060 05 is active when the cooling fan is unplugged, repair or replace the fan control clutch. Erase fault code memory.
- If new fault 060 05 is not active when the cooling fan is unplugged, go to step 2 .
- Measure the resistance between wire 41 and wire 12 on the 55-pin connector. See Figure
"Location of Fan Control Wires "
.
- If the resistance is less than 30 kΩ, repair short circuit between wire 41 and wire 12 on the 55-pin connector. Erase fault code memory.
- If resistance is greater than 30 kΩ, go to step 3 .
- Measure the resistance between wire 43 and wire 12 on the 55-pin connector. See Figure
"Location of Fan Control Wires "
.
- If resistance is less than 30 kΩ, repair short circuit between wire 43 and wire 12 on the 55-pin connector. Erase fault code memory.
- If resistance is greater than 30 kΩ, go to step 4 .
- Measure the resistance between wire 43 and vehicle ground.
- If resistance is greater than 30 kΩ, contact Detroit Diesel Technical Service.
- If resistance is less than 30 kΩ, repair short to ground in wire 43 of the 55-pin connector. Erase fault code memory.
