2009 Toyota Yaris Parts Questions & Experts Answers

• Q: How to install the Engine Control Module (ECM) on 2009 Toyota Yaris?

  A: When installing the 1NZ-FE engine control system ECM start by securing ECM bracket No. 2 with two screws then install the ECM bracket holding it in place with another two screws. The ECM needs a bolt and two nuts tightened to 8.0 Nm (82 kgf-cm, 71 in-lbf) before connecting its two connectors and applying two lock knobs along with the harness clamp. First secure the ECM with a bolt that gets tightened using 2 nuts to maintain the specified torque of 8.0 Nm (82 kgf-cm, 71 in-lbf). After securing the ECM, use the connectors to join both terminals before installing lock knobs with the harness clamp. The hatchback requires installation of its cowl top panel outer while the sedan requires installation of both its cowl top panel outer with 8 bolts at 6.5 Nm torque strength and its cowl top panel outer center bracket at the same torque level before wire harness connection and claw engagement. Fix the front air shutter seal of the sedan into position by connecting 3 claws. After operational installation of windshield wiper motors and links on hatchback and sedan models customers should execute cowl top ventilator louver sub-assembly installation for each version. Position the hood to cowl top seal on the hatchback and set the cowl side ventilator sub-assemblies into the sedan model. Completion of the assembly involves the installation of wiperarms and wiperooms onto the left and right sides of both hatchback and sedan where front wiper arm head caps will be placed before cable connection to the negative battery terminal with 5.4 Nm (55 kgf-cm, 48 in-lbf).
