N ENGINE SPEED SENSING POWER STEERING Caution Never hold the steering wheel to the extreme left or right for more than five seconds with the engine running. This could damage the power steering d pump- 8. Turn the steering wheel fully to the left and right and measure the fluid pressure generated by the gear hous- ing. If the pressure is not within specification, replace the gear housing assembly. Gear housing fluid pressure: 7,601--8,335 kPa (77.545.0 kgflcm2, 1,103-1,208 psi) 9. Remove the gauge set. Install and tighten the pressure hose to the specified torque. Tightening torque: 3247 N.m (3.24.8 kgf.m, 24--34 ft.lbf} 10. Bleed the air from the system. (Refer to page N-21.) STEERING WHEEL AND COLUMN Obtain the code number and deactivate the audio anti- theft system before disconnecting the battery. (Refer to section T.) On-vehicle Inspection -1 Steering wheel effort 1. With the vehicle on a hard, level surface, put the wheels in the straight-ahead position. 2. Start the engine and warm the power steering fluid to 50--60°C (1 22-1 40°F). 3. With the engine running at idle, attach a pull scale to the outermost point of the steering wheel spoke. Then, starting with the wheels in the straight-ahead posi- tion, measure the effort required to turn the steering wheel to the left and to the right. Steering wheel effort: 2635 N (2.63.6 kgf, 5.3-7.9 Ibf) (during one turn of the steering wheel) 2 4. If not within specification, check the following: fluid level, air in system, fluid leakage at hose or connections, func- tion of oil pump and steering gear, and tire pressure. Gartner Banana

P ANTILOCK BRAKE SYSTEM (ABS) TROUBLESHOOTING GUIDE Troubleshooting Guide with ABS Tester ABS tester ADAPTER PART No.0000-42-0010 HYDRAULIC UNIT CONNECTOR POSSlTlVE BATTERY 97UOPX469 Connecting ABS tester 1. Turn the ignition switch OFF. 2. Connect the SST harness to an extension harness, and wrap the connection with electrical tape to prevent short- ing. 3. Connect the SST between the hydraulic unit wiring har- ness connectors and to the positive battery terminal. 4. Roll back the carpet and remove the protecter. 5. Connect the ABS tester to the control unit connector at harness side .using the adaptor. Warning Driving the vehicle while the tester is connected to the ABS control unit is extremely dangerous. The brakes could fail, resulting in death or seri- / -1 ous injury. Disconnect the tester from the ABS control unit before driving the vehicle. Gartner Banana
