Power Steering System Acura TL III

SUPPLEMENTAL RESTRAINT SYSTEM (SRS) (If steering maintenance is required)

The Acura TL SRS includes a driver's airbag in the steering wheel hub, a passenger's airbag in the dashboard above the glove box, seat belt tensioners in the front seat belt retractors, side curtain airbags in the sides of the roof, and side airbags in the front seat-backs. Information necessary to safely service the SRS is in SRS (SUPPLEMENTAL RESTRAINT SYSTEM)

1. To avoid rendering the SRS inoperative, which could lead to personal injury or death in the event of a severe frontal or side collision, all SRS service work must be performed by an authorized Acura dealer.
2. Improper service procedures, including incorrect removal and installation of the SRS, could lead to personal injury caused by unintentional deployment of the airbags and/or side airbags.
3. Do not bump or impact the SRS unit, front impact sensors, or side impact sensors when the ignition switch is ON (II), or for at least 3 minutes after the ignition switch is turned OFF; otherwise, the system may fail in a collision, or the airbags may deploy.
4. SRS electrical connectors are identified by yellow color coding. Related components are located in the steering column, front console, dashboard, dashboard lower panel, in the dashboard above the glove box, in the front seats, in the roof side, and around the floor. Do not use electrical test equipment on these circuits.

Check the cylinder lines A and B for deformation (see «POWER STEERING HOSE, LINE, AND PRESSURE SWITCH REPLACEMENT»(/acura/tl/iii-2003-2006/remont/manual-power-steering/#power-steering-system__power-steering-hose-line-and-pressure) ). Are the A or B lines deformed? YES - Replace the lines. NO - Go to step 12.
12. Check for 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 gearbox and linkages are OK. If the play exceeds the limit, adjust the rack guide (see «RACK GUIDE ADJUSTMENT»(/acura/tl/iii-2003-2006/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 gearbox (see «STEERING LINKAGE AND GEARBOX INSPECTION»(/acura/tl/iii-2003-2006/remont/manual-power-steering/#power-steering-system) ).

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/tl/iii-2003-2006/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 (Scheme 4)and read it as soon as the tires begin to turn. If the scale reads no more than the specification, the gearbox and pump are OK. If the scale reads more than the specification, troubleshoot the steering system (see «SYMPTOM TROUBLESHOOTING»(/acura/tl/iii-2003-2006/remont/manual-power-steering/#power-steering-system) ).
