Symptom: There can be two coolant level sensors (typically on the Bus Applications) that are related to the coolant level sensor. One coolant level sensor is connected to the ECM and the fault code, the other coolant level sensor is connected to the OEM as the dashboard light. Verification is the fault code can only be cleared and issue corrected by troubleshooting the correct coolant level sensor. Before beginning the troubleshooting process, the correct sensor that connects back to the ECM must be identified. When the ECM is powered down the OEM sensor will still have voltage. If there are two coolant level sensors, identify the correct ECM connected coolant level sensor and continue with the normal troubleshooting steps","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2022/MC-10224325-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2022/MC-10224325-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10224325","components":[{"id":"driver-assistance","name":"Driver assistance","parent":null},{"id":"engine","name":"Engine","parent":null},{"id":"lighting","name":"Lighting","parent":null},{"id":"backup-camera","name":"Backup camera","parent":"driver-assistance"},{"id":"engine-control-module","name":"Engine control module","parent":"engine"}],"codes":[],"topics":[],"vehicles":[{"make":"CUMMINS","model":"B6.7","year_from":null,"year_to":null,"match":null,"vehicle_ids":[]},{"make":"CUMMINS","model":"ISX12","year_from":null,"year_to":null,"match":null,"vehicle_ids":[]},{"make":"CUMMINS","model":"L9","year_from":null,"year_to":null,"match":null,"vehicle_ids":[]},{"make":"CUMMINS","model":"X12","year_from":null,"year_to":null,"match":null,"vehicle_ids":[]},{"make":"CUMMINS","model":"X15","year_from":null,"year_to":null,"match":null,"vehicle_ids":[]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
