Some 2009 – 2010 Corolla and Matrix vehicles may exhibit a clunk, pop, or knocking noise when turning the steering wheel to the left or right. A new intermediate shaft has been developed to address this condition. Use the following repair procedure to remove and replace the steering intermediate shaft. Repair Procedure 1. Install a steering wheel lock to ensure the wheels are straight and the steering wheel is centered before removing the steering intermediate shaft. Make sure the steering wheel and front wheels remain stationary. Once the intermediate shaft is removed, do NOT allow the steering wheel to spin freely. 2. Remove the column hole silencer sheet. 3. Place a matchmark on the No. 2 steering intermediate shaft that will later be copied onto the new part, and remove the bolt. 4. Place a matchmark on the upper portion of the No. 2 steering intermediate shaft. 5. Remove the bolt and the No. 2 steering intermediate shaft assembly from the steering column assembly. 6. Place the matchmarks on the NEW steering intermediate shaft sub-assembly. A. Place the NEW steering intermediate shaft next to the original steering intermediate shaft assembly (removed in the previous step). B. Transfer the matchmarks on the original steering intermediate shaft to the same locations on the NEW steering intermediate shaft. Figure 5. 1 Original Steering Intermediate Shaft 7. Install the NEW No. 2 intermediate shaft and line up the matchmarks and tighten the bolt. Torque: 35 N*m (360 kgf*cm, 26 ft*lbf) 8. Install the No. 2 intermediate shaft onto the No. 1 intermediate shaft and line up the matchmarks, and tighten the bolt. Torque: 35 N*m (360 kgf*cm, 26 ft*lbf) 9. Reinstall the column hole silencer sheet. 10. Road test the vehicle to verify the repair and con?rm that the steering wheel is centered.

Inspect the front pads for any irregular wear by loosening the two bolts on the brake caliper assembly. 3. Remove the brake caliper assembly and support it to prevent damage to the ?exible line. 4. Inspect the front pads for wear. If the pads are worn excessively, then replace the pads with the new part number. 5. Add disc brake caliper grease to both sides of the pad support clips and the anti-squeal shims. Figure 3. Figure 4. 2 1 1 No. 1 Disc Brake Pad Support Plate 2 No. 2 Disc Brake Pad Support Plate : 1 1 Add Grease Here (Pad Support Clips) NOTE Install the new anti-squeal shims and the pad wear indicators to the brake pads in the correct position to ensure quiet operation. Figure 5. : 1 1 Add Grease to These Surfaces 6. Install the pads into the brake caliper support assembly. 7. Install the brake caliper and tighten the caliper bolts. Torque: 34 N*m (347 kgf*cm, 25 ft*lbf) 8. Install the wheel and tighten the wheel nuts. Torque: 103 N*m (1050 kgf*cm, 76 ft*lbf) 9. Road test the vehicle to con?rm that there are no further issues with the brake system.

CAUTION: If ECM replacement is instructed in following testing, always ensure ECM connectors and ground circuit are okay. If either are suspect, repair and repeat testing to confirm ECM malfunction. Circuit Description The EGR system recirculates exhaust gas through intake system to reduce combustion temperature and NOx emissions. The amount of EGR valve opening is regulated by the EGR vacuum modulator according to engine load. Vacuum source to valve is controlled by the Vacuum Switching Valve (VSV), which is controlled by The EGR valve is closed (VSV on) under the following conditions: Engine is not warmed up. Vehicle under deceleration.
Light engine load. Engine racing.
