Troubleshooting SID 58

The following procedures will troubleshoot SID 58.‪

Section 21.2.1
058 03 – Constant Throttle Solenoid Valve Short to Power

Troubleshoot a Constant Throttle Solenoid Valve short to power fault as follows:‪

1. Determine if the engine has a constant throttle solenoid valve. See Figure "Location of Constant Throttle Solenoid Valve" .
   1. If the engine has a constant throttle solenoid valve, repair short to power in 55-pin connector wire 50. Erase fault code memory. See Figure "Constant Throttle Solenoid Valve Connector Wiring" .
      

      Figure 1. Constant Throttle Solenoid Valve Connector Wiring

   2. If the engine does not have a constant throttle solenoid valve, go to step 2 .
2. Check for a setting of Parameter 006 02.
   1. If Parameter 006 02 is not active, contact Detroit Diesel Technical Service.
   2. If Parameter 006 02 is active, set parameters 006 03 and/or 006 04 to “Not Active.” Erase fault code memory.

058 05 – Constant Throttle Solenoid Valve Open Circuit

Troubleshoot a Constant Throttle Solenoid Valve open circuit fault as follows:‪

1. Determine if the engine has a constant throttle solenoid valve. See Figure "Location of Constant Throttle Solenoid Valve" .
   1. If the engine does not have a constant throttle solenoid valve, go to go to step 2 .
   2. If the engine has a constant throttle solenoid valve, go to step 3 .
2. Check for a setting of Parameter 006 02.
   1. If Parameter 006 02 is not active, contact Detroit Diesel Technical Service.
   2. If Parameter 006 02 is active, set parameters 006 03 and/or 006 04 to “Not Active.” Erase fault code memory.
3. Bridge wires 1 and 2 on the constant throttle solenoid valve connector. See Figure "Constant Throttle Solenoid Valve Connector Wiring" .
   1. If new fault code 058 06 is active, go to step 4 .
   2. If new fault code 058 05 is active, go to step 5 .
4. Measure the resistance between wire 52 on the 55-pin connector and vehicle ground. See Figure "Constant Throttle Solenoid Valve Connector Wiring" .
   1. If resistance is less than 30 kΩ, repair short to ground in wire 52. Erase fault code memory.
   2. If resistance is greater than 30 kΩ, repair or replace the constant throttle solenoid valve. Erase fault code memory.
5. Measure the resistance between wire 52 and wire 50 on the 55-pin connector. See Figure "Constant Throttle Solenoid Valve Connector Wiring" .
   1. If resistance is less than 3 Ω, contact Detroit Diesel Technical Service.
   2. If resistance is greater than 3 Ω, repair open circuit or bad contact in wire 50 or 52. Erase fault code memory.

058 06 – Constant Throttle Solenoid Valve Short to Ground

Troubleshoot a Constant Throttle Solenoid Valve short to ground fault as follows:‪

1. Determine if the engine has a constant throttle solenoid valve. See Figure "Location of Constant Throttle Solenoid Valve" .
   1. If the engine has a constant throttle solenoid valve, go to step 2 .
   2. If the engine does not have a constant throttle solenoid valve, go to step 3 .
2. Measure the resistance between wire 50 on the 55-pin connector and vehicle ground. See Figure "Constant Throttle Solenoid Valve Connector Wiring" .
   1. If resistance is greater than 30 kΩ, contact Detroit Diesel Technical Service.
   2. If resistance is less than 30 kΩ, repair short to ground in wire 50. Erase fault code memory.
   3. If fault code 058 06 is still active, go to step 4 .
3. Check for a setting of Parameter 006 02.
   1. If Parameter 006 02 is not active, contact Detroit Diesel Technical Service.
   2. If Parameter 006 02 is active, set parameters 006 03 and/or 006 04 to “Not Active.” Erase fault code memory.
4. Measure the resistance between wire 50 and wire 52 on the 55-pin connector. See Figure "Constant Throttle Solenoid Valve Connector Wiring" .
   1. If resistance is less than 3 Ω, repair short circuit between wires 50 and 52. Erase fault code memory.
   2. If fault 058 06 is still active, go to step 5 .
5. Unplug the constant throttle solenoid valve .
   1. If new fault code 057 05 is active, repair or replace the constant throttle solenoid valve. Erase fault code memory.
