TROUBLESHOOTING CHART

Hard Steering

1. Check the power assist (see «STEERING WHEEL ROTATIONAL PLAY CHECK»(/acura/mdx/ii-2006-2010/remont/manual-power-steering/#power-steering-system) ). Is the initial turning load more than 29 N (3.0 kgf, 6.6 lbf) ? YES - Go to step 2. NO - Power assist is OK.
2. Connect the P/S joint adapter (pump), P/S joint adapter (hose), and P/S pressure gauge T/N 07406-0010001 (see «PUMP PRESSURE TEST WITH T/N 07406-0010001»(/acura/mdx/ii-2006-2010/remont/manual-power-steering/#power-steering-system__pump-pressure-test-with-tn-07406-0010001) ), T/N 07406-001000A or T/N 07406-001A101 (see «PUMP PRESSURE TEST WITH T/N 07406-001000A OR T/N 07406-001A101»(/acura/mdx/ii-2006-2010/remont/manual-power-steering/#power-steering-system__pump-pressure-test-with-tn-07406-001000a) ) to the pump.
3. Measure steady-state fluid pressure from the pump at idle. Is the pressure 1,470 kPa (15 kgf/cm 2 , 213 psi) or less? YES - Go to step 4. NO - Go to step 8 .
4. Measure the pump relief pressure at idle. Is the pressure 8,920- 9,420 kPa (91-96 kgf/ 2 , 1,290 - 1,370 psi) or more? YES - Go to step 5. NO - Go to step 9 .
5. With a spring scale, measure the power assist in both directions, to the left and to the right. Are the two measurements within 5.0 N (0.51 kgf, 1.12 lbf) of each other? YES - Go to step 6. NO - Go to step 11 .
6. Measure the fluid pressure with both pressure gauge valves open (if so equipped), while turning the steering wheel fully to the left and fully to the right. Is the pressure 8,920- 9,420 kPa (91-96 kgf/ 2 , 1,290 - 1,370 psi) or more? YES - Go to step 7. NO - Faulty steering gearbox.
7. Adjust the rack guide (see «RACK GUIDE ADJUSTMENT»(/acura/mdx/ii-2006-2010/remont/manual-power-steering/#power-steering-system__rack-guide-adjustment) ), and retest. Is the steering OK? YES - Repair is completed. NO - Faulty steering gearbox.
8. Check the outlet and return hoses and lines between the pump and the steering gearbox for clogging and deformation. Are the lines clogged or deformed? YES - Repair or replace the lines. NO - Faulty valve body unit.
9. Disassemble the pump (see «PUMP OVERHAUL»(/acura/mdx/ii-2006-2010/remont/manual-power-steering/#power-steering-system) ).
10. Check the flow control valve for smooth movement and leaks (see step 13 ). Is the flow control valve OK? YES - Faulty pump assembly. NO - Faulty flow control valve.
11. Check the cylinder lines for deformation (see «POWER STEERING HOSE, LINE, AND PRESSURE SWITCH REPLACEMENT»(/acura/mdx/ii-2006-2010/remont/manual-power-steering/#power-steering-system__power-steering-hose-line-and-pressure) ). Are any of the lines deformed? YES - Replace the deformed line. NO - Go to step 12.
12. Checker a bent rack shaft or misadjusted rack guide (too tight). Is the rack shaft bent or the rack guide adjusted too tight? YES - Replace the rack shaft, or readjust the rack guide. NO - Faulty valve body unit.

Scheme 3

1. Turn the front wheels to the straight ahead position.
2. Measure how far you can turn the steering wheel left and right without moving the front wheels. If the play is within the limit, the steering gearbox and linkages are OK. If the play exceeds the limit, adjust the rack guide (see «RACK GUIDE ADJUSTMENT»(/acura/mdx/ii-2006-2010/remont/manual-power-steering/#power-steering-system__rack-guide-adjustment) ). If the play is still excessive after rack guide adjustment, inspect the steering linkage and steering gearbox (see «STEERING LINKAGE AND GEARBOX INSPECTION»(/acura/mdx/ii-2006-2010/remont/manual-power-steering/#power-steering-system) ). Rotational play: 0-10 mm (0-0.39 in.)

Power Assist Check

Note. This test should be done with original equipment tires and wheels at the correct tire pressure.

Scheme 4

1. Check the power steering fluid level (see «FLUID REPLACEMENT»(/acura/mdx/ii-2006-2010/remont/manual-power-steering/#power-steering-system__fluid-replacement) ).
2. Start the engine, let it idle, and turn the steering wheel from lock-to-lock several times to warm up the fluid.
3. Attach a commercially available spring scale to the steering wheel. With the engine idling and the vehicle on a clean, dry floor, pull the scale as shown and read it as soon as the tires begin to turn. If the scale reads no more than the specification, the steering gearbox and pump are OK. If the scale reads more than the specification, troubleshoot the steering system (see «SYMPTOM TROUBLESHOOTING»(/acura/mdx/ii-2006-2010/remont/manual-power-steering/#power-steering-system) ).
