Hello everyone! I just bought a 2014 Sr250 from a provate dealer. It was kept up on all of its warranty work and this 3667 ATS Fail just came up on it. It still runs and operates great, but I think it's draining my battery. I shut the main disconnect off when it sits for more than a day and it's just fine. Any quick tips on taking care of this before I spend an arm and a leg at the Case Dealership?
Put a new Engine harness on it and egr motor. Repaired chassis harness. And pud serviced it right before I bought it.
EGR valve circuit open load error for power stage. Follow the appropriate service tool procedure to restore self learning parameters. I looked up the code definition. Maybe the dealer didn’t fix it properly,or it needs reprogramming. Did you check amp draw with multi meter?
I haven't checked the Amp draw yet. I was just hoping this code wouldn't be detrimental to the machine if I used it before I could get it re programmed properly. Thanks for the imput!
3667-Open load error for power stage Context: ECU Power stages : Open load error on the EGR valve power stage. Cause: The ECU detects an open circuit in the EGR valve drive circuit. Electrical problem in the EGR valve actuator. Possible failure modes: 1. Faulty wiring. 2. Faulty EGR valve. 3. Faulty ECU. Solution: 1. Verify that the fault code is active. Connect the Electronic Service Tool to the service tool connector. To check for fault codes: Start and operate the machine. A. The fault code is not recorded again. OK to return the machine to service. B. Fault code 3667 is recorded again. Go to step 2. 2. Verify that the wiring and connectors are free of damage. Inspect the ECU and the EGR valve. All connections should be secure, tight, free of corrosion, abrasion and damage. Inspect the harness from the ECU to the EGR valve. Verify that the harness is free of damage, corrosion, abrasion and incorrect attachment. A. The connectors are secure and the harness is free of damage. Go to step 3. B. The connectors or the harness has damage. Repair or replace the harness or connectors as required. Return to step 1 to confirm elimination of fault. 3. Measure the resistance through the wiring harness Turn the ignition switch OFF. Disconnect the EGR Valve connector. Disconnect the ECU connector. Measure the resistance between ECU connector X-016 pin 50 and EGR valve motor plus pin. The resistance should be less than 10 Ω. Wiggle the harness during measurement to reveal an intermittent condition. Measure the resistance between ECU connector X-016 pin 35 and EGR valve motor minus pin. The resistance should be less than 10 Ω. Wiggle the harness during measurement to reveal an intermittent condition. Measure the resistance between ECU connector X-016 pin 9 and EGR position sensor supply pin. The resistance should be less than 10 Ω. Wiggle the harness during measurement to reveal an intermittent condition. Measure the resistance between ECU connector X-016 pin 39 and EGR position sensor signal pin. The resistance should be less than 10 Ω. Wiggle the harness during measurement to reveal an intermittent condition. Measure the resistance between ECU connector X-016 pin 24 and EGR position sensor ground pin. The resistance should be less than 10 Ω. Wiggle the harness during measurement to reveal an intermittent condition. A. The resistance is less than 10 Ω. Go to step 4 Measure the resistance between ECU connector X-016 pin 35 and chassis ground. The resistance should be greater than 20,000 Ω. Wiggle the harness during measurement to reveal an intermittent condition. A. The resistance is greater than 20,000 Ω. Go to step 5. B. The resistance is less than 20,000 Ω. There is a short circuit to chassis ground. Repair or replace the wire as required. Return to step 1 to confirm elimination of fault. 5. Measure the resistance through the valve to chassis ground. Turn the ignition switch OFF. Disconnect the electric valve connector. Measure the resistance through the electric valve pin 1 to chassis ground. The resistance should be greater than 20,000 Ω. A. The resistance is greater than 20,000 Ω. Temporarily replace the ECU and retest. Return to step 1 to confirm elimination of the fault. B. The resistance is less than 20,000 Ω. There is an internal short to chassis ground. Temporarily replace the electric valve and retest. Return to step 1 to confirm elimination of the fault
Thanks Makar! I'll give this a shot!
