Connect the wire to the reverse light wire to resolve the issue. B3059 immobilizer code: No request received from the engine management system (R-line malfunction). Disconnect the power for ten minutes to fix it. Remember that the immobilizer system should be on (not locked) before power disconnection. The R-line represents the control wire.
As a Geely Emgrand owner, I have personally encountered the R-line fault issue in the anti-theft device, and the solution is not complicated. The R-line usually refers to the relay control circuit in the anti-theft system. If it malfunctions, the anti-theft function may completely fail or trigger false alarms. Once, my car didn't respond when locking, and upon inspection, I found the R-line was loose with poor connector contact. The solution requires a step-by-step approach: first, check the fuse box for anti-theft-related fuses and replace any blown ones; then inspect the relay—you can shake it by hand to test for abnormal sounds. If the wiring appears intact, use a multimeter to check if the voltage is normal. Finally, consider whether the anti-theft system itself is faulty, and if necessary, visit a 4S shop to refresh or replace the unit. Regular maintenance should include cleaning wiring connectors to prevent dust and water damage, which can extend lifespan. The anti-theft system is crucial—don’t overlook it.
