How to remove the Engine Control Module (ECM) on Toyota Highlander?

The removal process of the Engine Control Module (ECM) requires first unplug the battery cable from the negative terminal followed by a potential need for system initialization after reconnecting. Start by removing the front door scuff plate on the right-hand side of the vehicle and then proceed to remove the cowl side trim sub-assembly on the right-hand side. Next you should eliminate the No. 2 instrument panel under cover sub-assembly and the lower instrument panel sub-assembly. The procedure for ECM removal begins with disconnecting all 6 ECM connectors then moving to disconnect the tire pressure warning ECU connector before extracting the nut while taking out the tire pressure warning ECU and disconnecting its wire harness clamps. After removing the 2 nuts together with the bolt and ECM with bracket from the vehicle proceed to delete the 4 screws and their accompanying ECM brackets which connect to the ECM.

How to install the Engine Control Module (ECM) on Toyota Highlander?

The installation process for the 2GR-FE engine control system requires installing the No. 2 ECM bracket using 2 screws while the No. 1 ECM bracket needs 2 more screws. Subsequently, secure the system with 2 nuts and a bolt and tighten the bolt to 8.0 Nm (82 kgf-cm, 71 in-lbf). Installation of the ECM starts with threading two nuts and single bolt followed by applying 8.0 Nm (82 kgf-cm, 71 in-lbf) torque before attaching the wire harness clamp and joining 5 ECM connectors with the harness connector. The installation then moves towards the tire pressure warning ECU followed by the certification ECU and Smart Key ECU assembly (if Smart Key System is included). The installation of the lower instrument panel sub-assembly follows the same procedure for the left-hand side while installing the No. 2 instrument panel under cover sub-assembly alongside the cowl side trim sub-assembly on the right-hand side and the front door scuff plate on the right-hand side. Attach the cable to the negative battery terminal while acknowledging systems which could need an initialization process post-installation. Replacement of the tire pressure warning ECU requires transmission ID registration along with inspection of the system which must include transmitter ID registration for all tires before starting the initialization process. The immobiliser system (with or without Smart Key System) requires registration of its ECU communication ID after replacing the ECM then perform initialization followed by a memory reset for automatic transmission.

The Toyota Highlander Engine Control Module remains one of the most trusted and efficient ECMS for the above models as it controls and supervises the operation of the engine. This advanced ECM takes information from as many as fourteen sensors including oxygen and throttle position sensors and determines components like air-fuel ratio and idle speed. Through the proper management of fuel injection and turning on and off the ignition coils, the Toyota Highlander ECM improves the fuel burn in the cylinder helping to improve the fuel efficiency and reduce emissions. Fitment for compatibility is another since the Engine Control Module is compatible with different varieties of Highlander, ranging from the standard production version to the Hybrid Model. In today's Highlander automobiles the advanced micro processor controls enable extra features including the ability commonly recognized as variable valve timing besides combining with the controls of the transmission system to make the driving experience all the better. It is worthy to state that certain types of ECMs could be programmed, and this usually opens up new options for tuner enthusiasts. The Toyota Highlander is a midsize SUV with five and seven passengers versions which also can be ordered with the front- wheel or all-wheel drive. There are model hybrids, which enhance a car equipped with the Toyota Hybrid Synergy Drive system, and which characterizes the brand from the point of view of technological development as cars that can move in electric-only mode at low speeds. On balance, the Toyota Highlander Engine Control Module forms a distinctive part of the automotive market because of its essential function to improve the flow of the car's functions and to make traveling safe and secure to ensure the reputation of Toyota as the maker of reliable and powerful vehicles.
