2006 F-150 Remote Starter Installation Causes P0104, P0605, and B1352 Fault Codes - Expert Diagnosis Required

Model: 2006 F-150 Fault Code: B1352 Posted: 2016-02-18 14:44

I installed a Viper 7345V remote starter in my 2006 Ford F-150 on February 10, 2016. On February 11, the check engine light activated. I returned to the installer, who stated it was not related to their work. I then visited an auto repair shop, which diagnosed three fault codes: P0104 (Mass Airflow Sensor Circuit Malfunction), P0605 (Internal Control Module ROM Error/Interference from Non-OEM Electronic Device), and B1352 (Powertrain Control Module Communication Issue). The shop replaced the Mass Airflow Sensor and cleared the codes. However, on February 15, 2016, the check engine light returned. A follow-up scan revealed P0605 — indicating an internal error in the control module due to interference from a non-OEM electronic device. The remote starter installer claims their installation did not cause any issues and refuses to inspect their work for potential problems such as frayed wiring or defective components. I am now wondering whether there are additional diagnostic steps I should have taken before pursuing further investigation with the remote starter installer, especially given that P0605 is a critical fault related to the vehicle's electronic control module.

Remote starters can interfere with a vehicle's onboard electronics. The pattern here — no issues before installation, problems after — strongly suggests an electronic conflict. A practical solution: have the remote starter removed and test if symptoms resolve. This helps isolate whether the device is causing the fault codes.

The situation escalated after I met with the installer's manager, who agreed to remove the remote starter at their expense ($50). It took three weeks for them to schedule the removal due to shop capacity — a clear lapse in customer service. After removing the unit, the check engine light remained on. While I initially thought disconnecting the battery would clear it (a common fix), my case involved a 'hard code' that required professional clearing via an authorized repair shop's diagnostic system ($55.99). However, just four hours later, the light returned. This indicates a serious issue: the original remote starter installation likely corrupted the vehicle’s control module programming. The auto repair shop concluded that the internal control module was damaged and must be replaced and reprogrammed by a Ford dealer — a costly process. I eventually took my 2006 F-150 to a Ford dealership, where I was greeted by Amber, who listened carefully to my story. Duane, a technician, joined the discussion and inspected the vehicle. After an hour of work and at a cost of $162.07, the truck was cleaned and the check engine light was completely off. Duane explained that the remote starter installation had corrupted the control module's programming, requiring re-flashing with factory codes. This experience reinforced a key lesson: when driving a Ford vehicle, always take it to an authorized Ford dealer for any electronic modifications. Vehicle-specific electronic systems are highly sensitive and only properly supported by OEM dealerships.
