download
Correction 1. Visually inspect the tires and the wheels. Inspect for evidence of the following conditions and correct as necessary: 2. Set the tire pressure to 30 psi (205 kPa) COLD. Subject: Shake/Vibration in Steering Wheel, Floor, Seat at Highway Speeds on Smooth Roads (Diagnose/Balance Tires/Wheels) Models: 1998-2005 Buick Park Avenue, Park Avenue Ultra 2000-2005 Buick LeSabre 1998-2004 Cadillac Seville (SLS, STS) 2000-2005 Cadillac DeVille (DTS only) 2001-2003 Oldsmobile Aurora 2000-2005 Pontiac Bonneville (17″ Tires only) • Missing balance weights • Bent rim flange • Irregular tire wear • Incomplete bead seating • Tire irregularities • Mud/ice build-up in wheel • Stones in the tire tread © 2009 General Motors Corporation. All rights reserved 3. Road test the vehicle with the Electronic Vibration Analyzer (EVA) essential tool for a sufficient distance on a known, smooth road surface to duplicate the condition. Record the Hertz (Hz) reading as displayed by the EVA onto the tire data worksheet found at the end of this bulletin. This should be done after a tire break-in period of at least 10 miles (16 km) at 45 mph (72 km/h) or greater, in order to eliminate any possible tire flat-spotting. 4. If the road test indicates a shake/vibration still exists, check the imbalance of each tire/wheel assembly on a known, calibrated, off-car dynamic balancer. If any assembly calls for more than ¼ ounce on either rim flange, remove all balance weights and rebalance to as close to zero as possible. Important: Some GM dealers may have a Hunter GSP9700 Road Force Balancer, or a Coats XR1850 Runout Balancer. Either will simplify Step 5 by not requiring dial indicators. If a Hunter GSP9700 machine is available, it may also be used to measure the radial force of the tire/wheel assembly. A guideline here is 18 lbs or less. 5. While on the balancer, measure wheel runout. If radial or lateral runout exceeds .020 in (0.50 mm) for aluminum wheels (.030 in (0.76 mm) for steel wheels), replace the wheel. 6. After confirming wheel balance and wheel runout, if any changes were made, road test the vehicle again. 7. If the smooth road shake/vibration still exists: Important: THE CONTROL ARMS SHOULD ONLY BE INSTALLED ON VEHICLES IF, AFTER THE TIRE AND WHEEL DIAGNOSIS AND REPAIRS HAVE BEEN PERFORMED, THE VIBRATION CONDITION STILL EXISTS. 8. Replace both lower control arms on vehicles built prior to the following VIN breakpoints. On Aurora, Bonneville, DeVille, Park Avenue, Park Avenue Ultra and Seville models, a newly developed hydro-bushing lower control arm with improved damping characteristics has been released. This control arm is not used on the LeSabre. The new lower control arms may provide an incremental improvement to the vehicle ride. Customers who have become “tuned in” to the shake condition may still feel some shake in the vehicle after the new lower control arms are installed. Refer to Lower Control Arm Replacement in SI (refer to the Parts Information table below for SI document ID numbers) . Important: The completed worksheet must be attached to the hard copy of the repair order. • If a Hunter GSP9700 Road Force/Balancing machine is used, record radial force variation (RFV) on the worksheet at the end of this bulletin. If one or more of the tire/wheel assemblies read more than 18 lbs, match mount the tire to the wheel to get below 18 lbs. Readings of 12 lbs or less are preferable for sensitive customers. • If a Coats XR1850 Runout/Balancing Machine is used, record radial runout of the tire/wheel assemblies on the worksheet at the end of this bulletin. If one or more of the tire/wheel assemblies are more than .040, match mount the tire to the wheel to get below .040. Readings of .030 inch or less are preferable for sensitive customers. • If the RFV or runout cannot be reduced to an acceptable level, replace the affected tire(s) under the guidelines of the GM Tire Warranty. • The screened tire program is only available for the General branded tires used on the Buick LeSabre. Complete the tire request form at the end of this bulletin and fax to Continental/General. • Road test the vehicle to ensure the shake/vibration has been eliminated

Battery Electrical Drain/ Parasitic Load Test Repair Manual

1. Disconnect the battery negative cable 2. Install the male end of the J 38758 to the negative battery terminal. 3. Turn OFF the test switch. 4. Install the negative battery cable to the female end of the test switch. 5. Install the Scan Tool (or equivalent) or wait for 20 minutes. 6. Turn ON the test switch. 7. Road test the vehicle while activating all accessories, including the radio and the air conditioning. 8. Lower the door glass, then exit the vehicle. Do not move the door handle after closing the door. 9. Open the hood. Important The power down timer will reset to 20 minutes if any wake up inputs are received by a Class 2 device (after the scan tool has put all Class 2 devices to sleep). 10. Put all of the Class 2 devices into the sleep mode. 11. Turn OFF the ignition switch. Remove the key. Important From this point on, electrical continuity must be maintained in the ground circuit of the battery through the Test Switch J 38758 in the ON position or through the ammeter J 39200 . 12. Components such as PCM, VCM, Automatic Air Conditioning, and the Truck Body Control Module have timers that draw several amps of current while they cycle down. This can give a false parasitic drain reading. Wait 20 minutes for these components to power down before continuing this test (or use the scan tool to put all Class 2 devices to sleep). 13. Connect a jumper wire with a 10 A fuse J 36169-A to the terminals of the test switch. 14. Turn the test switch to the OFF position. 15. Wait ten seconds. If the fuse does not blow, the current is less than 10 A. The ammeter can be used safely. 16. Before the fused jumper wire is removed, turn the test switch to the ON position. Important If an ammeter other than the J 39200 is used, ensure that the vehicle does not have a high current drain that would damage the ammeter when connected to the circuit. 17. Perform the following procedure in order to detect a high current drain: A. Set the ammeter J 39200 to the 10 A scale. B. Connect the ammeter to the test switch terminals. C. Turn OFF the test switch. This allows the current to flow through the ammeter. D. Wait one minute, then inspect the current reading. Ñ When there is a current reading of 2 A or less, turn ON the test switch, this maintains continuity in the electrical system. Ñ Then, switch the meter down to the 2 A scale, for a more accurate reading, when the test switch is reopened. E. Open the test switch. F. Take the reading in milliamps. G. Note the battery reserve capacity. Refer to Battery Usage . Ñ Divide this number by 4. Example: 90/4 = 22.5 Ñ Compare this to the ammeter reading. Ñ The current drain in milliamps should not exceed this number. Ñ Example: if a battery has a reserve capacity of 90 minutes, the current drain should not exceed 22 milliamps. H. When the current draw is too high, remove the electrical system fuses one at a time until the draw returns to a value less than or equal to specifications. Ñ Start with the fuses that are hot all the time. Ñ To remove the fuse, you must first open the door, which causes a high enough current flow to damage the ammeter. Ñ Protect the ammeter, without disturbing the electrical continuity, by turning ON the test tool before opening the door. Ñ Remove the courtesy lamp fuse. Ñ Note the ammeter reading. Ñ If the parasitic load is still excessive, start removing the remaining fuses one at a time. Ñ Keep the courtesy lamp fuse out during diagnosis, so the door can remain open. Ñ Perform Steps 11 through 13 each time a fuse is removed. I. Removing the PCM or VCM fuse should cause a drop of less than 10 milliamps. A drop greater than 10 milliamps indicates a possible short to ground. J. Check the orange wires along with the components connected to the orange wires. No drop in the milliampere reading indicates the PCM or VCM is not drawing current. K. Repeat the parasitic current drain test procedure after any repair has been completed. L. When the cause of the excessive current draw has been located and repaired, remove the ammeter and the parasitic draw test switch.

With the ignition switch in the RUN position, test for battery voltage at the circuit fuse in the transmission solenoid power supply circuit. Refer to the appropriate SI Document for the transmission solenoid power supply circuit information. 2. If battery voltage is present at the fuse, inspect the ignition voltage circuit between the fuse and the transmission for possible opens. 3. If battery voltage is not present at the fuse, test for continuity between the fuse and the ignition switch. If NO ontinuity is between the fuse and the ignition switch, repair the open in that circuit. 4. If you have continuity between the fuse and the ignition switch, the most likely cause is the ignition switch. Replace the ignition switch using the appropriate Ignition Switch Replacement procedure in SI. Refer to group number 2.188 of the parts catalog for part description and usage of the ignition switch.
