2002 Toyota Sienna

Dear Sir, On April 2026, I need to do the semiannual smog check. Right now, I face DTC P0420 error code and I can't pass the smog check inspection. Note that I don't have the engine light on indicating the a/m error code. Only my OBD2 shows the error DTC Code P0420. I did some searhing and noticed that the ECM for Sienna should be updated to erase the a/m DTC code. I would appreciated to help me how the resolve this issue ASAP. It will enable me to renew my registration.You may contact on my cell phone 747 217 7254 or my email at [email protected]. Regards, Massey

BRAKES MAKE A NOISE WHEN THE CAR IS ABOUT TO STOP. THERE IS A SQUEAL AND THUMP THAT CAN BE HEARD. HAVE TAKEN THIS IN SEVERAL TIMES TO BE FIXED. THEY SAY THE BRAKES ARE SAFE. I AM 74 YEARS OLD AND HAVE HAD MANY CARS OVER THE YEARS AND THE ONLY TIMES OTHER CARS HAVE MADE THIS KIND OF NOISE IT WAS TIME TO CHANGE THE BRAKES. IN THIS CASE THE BRAKE PADS SEEM TO HAVE PLENTY OF LIFE LEFT. FUNNY THAT WHEN THE REAR DRUMS ARE REMOVED AND THE BRAKE AND DRUMS ARE THOROUGHLY CLEANED THE NOISE DOES NOT HAPPEN FOR A WHILE. THE FIRST COMPLAINT WAS MADE AT 15,523 MILES AND CONTINUES TOO THIS DAY. AT 31,842 MILES THE REAR DRUMS WERE REPLACED PER TSB BR003-04. TOOK THE CAR IN AGAIN AT 125,559 MILES AND WE WERE TOLD WE NEEDED NEW REAR DRUMS. THEY HAD BEEN REPLACED. THEY HAVE A PROBLEM WITH BRAKES AND NEED TO FIX THE PROBLEM.

To prevent brake rotor rust from forming during transportation and storage, wheel film will be used instead of a cardboard type of anti-rust cover. The purpose of the wheel film is to shield the disc brake rotor from weather elements and initial rust before the vehicle is delivered to the customer. Consequently, the film should remain on the wheel for as long as possible.

The condition known as acid rain is caused by airborne chemicals or particles in the atmosphere, which mix with rainwater, nighttime dew, or high humidity to form acidic compounds. If these contaminants settle and remain on a painted vehicle surface, especially the horizonal areas of the hood, roof, and decklid, significant damage can occur. This damage is the result of actual etching of the paint and appears as pitting or water spots. As acid rain droplets on the vehicle surface evaporate, the concentration strength of the acid increases, causing deeper and more rapid damage. This evaporation and corrosive action also occur more rapidly on dark colored cars as direct sun heat increases. It is the dealer’s responsibility to protect and maintain the quality of the vehicle’s paint finish after receipt at the dealership prior to the first sale. In areas known for high frequency and/or concentration of acid rain, frequent vehicle washing during high heat or humidity periods will minimize the potential for paint damage caused by acid rain. It is further recommended that either reverse osmosis or deionized water be used to prevent water spotting.

Acid rain results from rainwater or other airborne moisture that become acidic due to industrial chemical impurities in the atmosphere. If these acidic compounds settle on an exposed vehicle, especially the horizontal areas such as the hood, roof, and decklid, significant damage to the painted surfaces can occur. Acid rain damage can typically be identified on vehicles by the presence of stains on the paint surface that resemble hard water spots. Unlike water spots however, acid rain damage cannot be removed by regular washing procedures. Also, because acid rain can etch and soften the paint, normal buffing or polishing repair procedures should not be attempted. This can cause further damage and result in visible depressions in the paint surface. The following are the three major categories of acid rain damage: •Minor damage: requires only buffing to repair. •Moderate damage: usually requires neutralizing, color sanding, and buffing. •Severe damage: extending beyond 1/2 mil of clearcoat on a pearl, metallic, or solid color, requires neutralization, sanding, and repainting. In cases where acid rain damage is minor, neutralization and buffing with a liquid-type paint finessing product may provide an adequate repair. Only specially formulated products outlined in this bulletin should be used for that purpose. Unfortunately, other than minor damage, there is no simple method of determining the actual extent (depth) of acid penetration other than color sanding a representative affected area until there is no visible etching or depressions, followed by measuring the amount of paint removed with either a magnetic or digital-type film thickness gauge. The procedures in this bulletin are intended for use by qualified body/paint technicians and should not be attempted by inexperienced personnel. It is the dealer’s responsibility to protect and maintain the quality of the vehicle’s paint finish after receipt at the dealership prior to the first sale. Perform frequent vehicle washing, as often as daily, during high heat and humidity periods to minimize the potential for paint damage due to acid rain exposure. This is especially important in geographical areas known for high frequency and concentration of acid rain and industrial fallout.

Toyota vehicles are currently protected with RapgardTM protective film designed to protect the horizontal painted surfaces. This material protects from acid rain, environmental fallout, and rail contamination. Follow the Removal Procedure in this bulletin to remove the RapgardTM protective film within 90 days from initial application.

Vehicles may occasionally be subjected to contamination by airborne iron particles shed from railroad tracks, train wheels, exposure to heavy machinery facilities, grinding, welding, etc. This type of contamination can be identified by the presence of small, red or brown particles on the paint surface. These particles are often difficult to see on dark color paints but can be easily felt when brushing a hand across horizontal body surfaces such as the hood, roof, or deck lid. Follow the Repair Procedure in this bulletin to clean vehicles that may have been subjected to contamination by airborne iron particles such as rail dust during rail transportation or extended storage near industrial areas.
