PROCEDURE
INSTALL POWER STEERING MOTOR ASSEMBLY (for TMC Made)
Note
Do not drop the power steering motor assembly, strike it with tools or subject it to impacts.
If the power steering motor assembly is subjected to an impact, replace it with a new one.
Do not pull the wire harness and tilt steering support bond cable of the power steering motor assembly.
Do not allow any moisture to come into contact with the power steering motor assembly.
Do not loosen any bolts not mentioned in the procedure.
Do not allow any foreign objects to contaminate the power steering motor assembly.
Apply grease to the serrated part of the electric power steering column sub-assembly.
Note
First wipe off the existing grease from the serrated part, and then apply the dedicated grease supplied with a new power steering motor assembly or electric power steering column sub-assembly.
Temporarily install the power steering motor assembly to the electric power steering column subassembly with the 2 bolts.
Note
When temporarily installing the 2 bolts to the power steering motor assembly, do not tighten them all the way down.
| *1 | Wooden Block |
Secure the steering column assembly in a vise using aluminum plates and a piece of cloth.
Note
Do not overtighten the vise, as the steering column assembly may become deformed.
Secure the power steering motor assembly so that it is directly upright.
Support the steering column assembly with a wooden block or similar item to ensure that it does not fall.
Using SST, turn the steering main shaft once 180 degrees to the left and then 180 degrees to the right at a speed of 60 rpm, and repeat 2 to 3 times to adjust the axis centering of the power steering motor assembly.
Tighten the 2 bolts.
Using SST, measure the turning torque of the steering main shaft.
Note
Ensure that there is no abnormal resistance during rotation.
If the torque is not as specified, readjust the axis centering of the power steering motor assembly.
Install the 2 new clamps and tape to the wire harness as shown in the illustration.
| *1 | Power Steering Motor Wire Harness | *2 | Torque Sensor Wire Harness |
| *3 | Tape A | *4 | No. 3 Clamp |
| *5 | Tape B | *6 | No. 2 Clamp |
| *a | 358 to 378 mm | *b | 152 to 168 mm |
| *c | 60 to 100 mm | *d | 80 to 100 mm |
| *e | 373 to 393 mm | *f | 105 mm |
Note
Wrap the tape at least 1.5 turns.
Pass the torque sensor wire harness through the cutout of a new protector.
Engage the clamp and install the protector to the steering column assembly.
Note
Make sure the wire harness is not pinched between the protector and the steering column assembly.
Engage No. 2 clamp and install the wire harness to the protector.
Pass a new No. 1 clamp through the groove in the protector, and tighten it within area A shown in the illustration to secure the protector and wire harness to the power steering motor assembly.
Note
Make sure there is no rattling or looseness in the protector.
Tech Tips
Fastening power for No. 1 clamp: 200 N (20 kgf)
Coat the protector with paint.
Cut off the excess length of No. 1 clamp.
INSTALL POWER STEERING MOTOR ASSEMBLY (for TMMF Made)
Note
Do not drop the power steering motor assembly, strike it with tools or subject it to impacts.
If the power steering motor assembly is subjected to an impact, replace it with a new one.
Do not pull the wire harness and tilt steering support bond cable of the power steering motor assembly.
Do not allow any moisture to come into contact with the power steering motor assembly.
Do not loosen any bolts not mentioned in the procedure.
Do not allow any foreign objects to contaminate the power steering motor assembly.
Apply grease to the serrated part of the electric power steering column sub-assembly.
Note
First wipe off the existing grease from the serrated part, and then apply the dedicated grease supplied with a new power steering motor assembly or electric power steering column sub-assembly.
Using "TORX" socket wrench T40, temporarily install the power steering motor assembly to the electric power steering column subassembly with the 2 bolts.
Note
