2010 Toyota Yaris Engine Control Module Parts Q&A

• Q: How to install the Engine Control Module (ECM) on 2010 Toyota Yaris?

  A: The installation process for Engine Control Module (ECM) requires first mounting ECM bracket No. 2 with two screws and then attaching the ECM bracket with two more screws. After that, the ECM needs to be secured through a bolt and its two nuts which should be torqued to 8.0 Nm (82 kgf-cm, 71 in-lbf). The next step is to connect the two ECM connectors and install the two lock knobs and harness clamp. First tightly fasten a bolt through the ECM then install two nuts and torque them to 8.0 Nm (82 kgf-cm, 71 in-lbf). After this step, connect both ECM connectors while installing the lock knobs and securing the harness clamp. The hatchback requires installation of the cowl top panel outer but the sedan requires this assembly together with 8 bolts reaching a torque level of 6.5 Nm (66 kgf-cm, 58 in-lbf) before installing the cowl top panel outer center bracket following the same tightness requirements. Plug in all wire harnesses before activating the claw seal. Affix the front air shutter seal of the sedan by connecting three claws. The installation order starts with cowl to register duct sub-assembly No. 2 followed by the windshield wiper motor and link before moving to install the cowl top ventilator louver LH and its sub-assembly. The sedan requires the windshield wiper motor and link installation together with cowl top ventilator louver sub-assembly and cowl side ventilator sub-assemblies LH and RH and front wiper arm and blade assemblies LH and RH. You should install front wiper arm head caps to both sedan and hatchback models and connect the cable to the negative battery terminal while torquing it to 5.4 Nm (55 kgf-cm, 48 in-lbf).
