057 05 — Open Circuit in the Engine Brake Flap Solenoid Valve and Wiring

Perform the following procedures to troubleshoot an open circuit in the engine brake flap solenoid valve and wiring.‪

If the engine has no exhaust brake flap, perform the following step:‪

1. Read Parameter 00601.
   1. If Parameter 00601 is “Not Active”, contact Detroit Diesel Technical Service Group.
   2. If Parameter 00601 is “Active”, refer to “20.2.1.1 Required Actions” .

If the engine has an exhaust brake flap, perform the following steps:‪

1. Measure the resistance between the 55-pin connector wires 12 and 51 of the bridged exhaust brake. See Figure “Exhaust brake and Cooling Fan Wiring” .
   
2. Figure 2. Exhaust brake and Cooling Fan Wiring

   1. If the resistance is less than 3 Ω, contact Detroit Diesel Technical Service Group.
   2. If the resistance is greater than or equal to 3 Ω, refer to “20.2.1.2 Required Actions” .
3. Bridge the exhaust brake solenoid wires and read the active fault codes.
   1. If Fault Code 057 06 is present, refer to “20.2.1.3 Required Actions” .
   2. If there are no active fault codes, erase the fault code memory and troubleshooting is done.

Section 20.2.1.1
Required Actions

Perform the following steps to resolve 057 05 for an engine with no exhaust brake flap.‪

1. Set Parameters 00603 and 00604 to “Not Active”.
2. Erase the fault code memory.

Section 20.2.1.2
Required Actions

Perform the following steps to resolve 057 05 with an open circuit.‪

1. Repair open circuit and/or replace bad contacts in the 55-pin connector wires 51 and/or 12.
2. Erase the fault code memory.

Section 20.2.1.3
Required Actions

Perform the following steps to resolve 057 05.‪

1. Remove and replace the exhaust brake flap solenoid valve.Note: The solenoid valve is typically located on the firewall.
2. Erase the fault code memory.

057 06 — Short in the Engine Brake Flap Solenoid Valve and Wiring

Perform the following procedures to troubleshoot a short in the engine brake flap solenoid valve and wiring.‪

If the engine has no exhaust brake flap, perform the following step:‪

1. Read Parameter 00601.
   1. If Parameter 00601 is “Not Active”, contact Detroit Diesel Technical Service Group.
   2. If Parameter 00601 is “Active”, refer to “20.2.2.1 Required Actions” .

If the engine has an exhaust brake flap, perform the following steps:‪

1. Measure the resistance between the 55-pin connector wire 12 and vehicle ground. See Figure “Exhaust Brake and Cooling Fan Wiring” .
   

   Figure 3. Exhaust Brake and Cooling Fan Wiring

   1. If the resistance is less than 30 kΩ, refer to “20.2.2.2 Required Actions” .
   2. If the resistance is greater than or equal to 30 kΩ, contact Detroit Diesel Technical Service Group.
2. Measure the resistance between the 55-pin connector wire 51 and vehicle ground. See Figure “Exhaust Brake and Cooling Fan Wiring” .
   1. If the resistance is less than 30 kΩ, refer to “20.2.2.3 Required Actions” .
3. Measure the resistance between the 55-pin connector wires 12 and 51. See Figure “Exhaust Brake and Cooling Fan Wiring” .
   1. If the resistance is less than 3 kΩ, refer to “20.2.2.4 Required Actions” .
4. Unplug the exhaust brake solenoid and read the active fault codes.
   1. If Fault Code 057 05 is present, refer to “20.2.2.5 Required Actions” .
   2. If there are no active fault codes, erase the fault code memory and troubleshooting is done.
