In a starter relay, the magnetism moves an armature or plunger to close a circuit. Transmission is confirmed to be physically in neutral. Engine is not running. Circuit Description: The starter lockout relay is controlled by the ECM through the starter lockout relay signal circuit. The relay prevents the starter from being engaged when the engine is running. Jun 20, 2017 路 The starter lockout relay is controlled by the ECM through the starter lockout relay signal circuit. A. TM 10-3930-675-20-1 0025 00-12 ENGINE BATTERY VOLTAGE CIRCUITS TROUBLESHOOTING - CONTINUED 0025 00 Table 4. Inspect Wiring and Connections: Check for damaged, frayed, or loose wiring and connectors associated with the engine starter motor solenoid lockout relay driver circuit. Remove the engine starter relay. Disconnect the 21-pin Motor Control Module (MCM) electrical connector. Consult the OEM wiring diagram for return circuit details. The Starter Solenoid Lockout Relay Driver Circuit is a solenoid driven by the ECM, which isolates the starter motor relay, electrically, when the engine is running. It outlines four key areas to check if the starter fails to engage: starter power, ignition ON circuits, ignition START control, and the start relay/solenoid/starter. Test Solenoid Relay Circuit: Use diagnostic tools to test the resistance and continuity of the starter solenoid relay driver circuit. When the ignition key is turned to the START position, it sends power to the “S” terminal on the starter solenoid. truckersfinalmile. opens the control circuit to the starter relay or solenoid. Refer to an OEM diagram for the exact location. Starter Solenoid Lockout Relay Driver Circuit Failure 1. Power runs from the battery to one terminal on the solenoid. This is fault code 17 and starts on page 141 or 145 depending on how you're viewing the manual. More than 10k ohms Starter Solenoid Lockout Relay Driver Circuit Page The starter relay (sometimes referred to as starter solenoid) is an electromagnetic switch that regulates the voltage from the battery to the starter when the ignition is in the “start” position. Circuit Description The starter lockout relay is controlled by the engine control module (ECM) through the starter lockout relay signal circuit. On that engine model the starter relay is feed on side (12 Volts) by the ignition switch and the other side (negative) by the engine ECU. EFFECT: Either the engine will not start or the engine will not have starter lockout protection. Measure the resistance between pin 21 of the MCM 21–pin connector and the engine starter relay. In a starter solenoid, the magnetic force created by current flowing through the coil causes the core to move out. It can be wired back to the ECM on some vehicles or #Bigbilly #Trucker #owneroperator #MercerPLEASE DONATE TO http://www. test or inspection. Sep 14, 2024 路 In this application, the starter solenoid acts only as a high-current relay to switch power to the starter motor.
