2003 Toyota Wiring Diagrams

A redesigned version of the Toyota 4Runner went on sale in October 2002. Adding a V-8 engine choice is just one of the notable changes that Toyota made to its popular sport utility vehicle. In the prior generation, a V-6 was the only power plant available, but the 2003 model offers both choices. The V-8-equipped model went on sale first, and the V-6 version should be on the market in January 2003, according to the Japanese automaker. Toyota expects that close to two-thirds of all 4Runners will have the V-6 engine.
 

The front and rear styling on Toyota's largest passenger car has been revised for the 2003 model year. The Avalon is considerably more distinctive in appearance and more noticeable than the company's class-leading, somewhat smaller Camry sedan. Last restyled for 2000, the upscale front-wheel-drive family sedan gets several comfort and safety changes for 2003. Multistage front airbags and ISOFIX child-restraint tethers are installed.
 

Toyota fully redesigned its Camry for the 2002 model year, so the midsize front-wheel-drive sedan sees only a handful of revisions for 2003. Fog lamps have been added to the XLE version, and all models equipped with automatic transmissions can have optional power-adjustable pedals.
 

After earning a modest face-lift for the 2002 model year, Toyota's Camry-derived midsize coupe and convertible are strictly carryovers for the 2003 season. Last year's appearance revisions in the Camry Solara included the addition of daytime running lights with an “off” switch, the availability of a new 2.4-liter four-cylinder engine, and a fresh front fascia with restyled features in the grille, bumper and headlights.
 

Toyota's rakish, low-slung sport coupe aims at an audience that's younger than buyers of the Camry Solara coupe. Unlike the company's MR2 Spyder, the Celica has a small backseat. A modest face-lift for the 2003 model year includes an updated front fascia, revised taillights and newly available high-intensity-discharge headlights. The gauge cluster has also been revised.
 

Few cars have a heritage as long as Toyota's popular compact. The Corolla has been on the U.S. market since 1966. More than 25 million units have been sold in 142 countries, and that makes the Corolla the best-selling passenger car of all time. Toyota dealers sold 245,023 eighth-generation Corollas in the United States during 2001, according to Automotive News. It has been Toyota's second-best seller behind only the midsize Camry.
 

Introduced for the 2000 model year and unconventional in appearance, these two- and four-door subcompact cars rely on a low price to attract youthful buyers. Being different often pays off in the sales race, and sometimes it doesn't. The final score has not yet been tallied for Toyota's entry-level Echo, which slots below the better-known Corolla in both size and price. So far, sales have been respectable, but the Echo has proven to be something less than a sensation.
 

Introduced early in the 2001 model year, the car-based Highlander is the fifth — and newest — member of Toyota's sport utility vehicle lineup. It is structurally related to the Lexus RX 300, but the Highlander is a little larger and has a different squared-off appearance. Fender creases are prominent on the Highlander, and fewer features are standard than on the RX 300, which is considerably more expensive. Both models are offered with front-wheel drive (FWD) or all-wheel drive (AWD), but the Highlander may be equipped with a four-cylinder engine or a V-6.
 

Toyota's most costly full-size sport utility vehicle has smaller dimensions than the newer Sequoia. The Land Cruiser has a history that dates back to the company's early days in the U.S. market. In recent years, it has been the slowest-selling member of the company's SUV group. Only 15,509 Land Cruisers were sold during 2000, according to Automotive News. The sales total dropped by more than half to just 7,591 units in 2001.
 

Toyota began shipping its new youth-focused Matrix to dealerships in February 2002 as an early 2003 model. Described as a crossover utility vehicle, the Japanese automaker says the Matrix combines the functionality of a sport utility vehicle with the image and performance of a sports car, yet it's as affordable as a subcompact sedan. “Young buyers want vehicles that are high in image and high in functional utility,” says Don Esmond, general manager of Toyota Division.
 

Toyota launched its two-passenger, rear-wheel drive sport convertible as a late 2000 model, reviving a name used in the 1990s for a similar mid-engine coupe. Last year, a new model of the MR2 Spyder with a five-speed sequentially shifted manual transmission (SMT) became available. 
 

Toyota's hybrid-powered four-door, five-passenger Prius sedan might look a little strange, but it's been attracting more attention than expected — and not just from environmentally concerned drivers. The high-tech, high-mileage sedan with its gasoline/electric powertrain is “a little more mainstream now,” says Don Esmond, vice president and general manager of the Toyota Division. “It wasn't just launching a car, it was launching a new technology.” The Prius' availability has leveled off, but in the summer of 2001, people seeking a Prius faced a three- to four-month waiting list.
 

With the RAV4's introduction in the 1997 model year, Toyota became one of the first manufacturers to offer a small, car-based sport utility vehicle. A second-generation RAV4, which was wider and longer than the original and came with a more powerful 148-horsepower, 2.0-liter four-cylinder engine, debuted for the 2001 model year. According to Automotive News, sales skyrocketed during 2001 — up a whopping 60.6 percent to 86,368 units.
 

Launched during the 2001 model year, Toyota's newest full-size sport utility vehicle evolved from the company's Tundra pickup truck and is built at the same Indiana plant. At nearly 204 inches long overall, the Sequoia is considerably longer than the Japanese automaker's own Land Cruiser. Toyota now has five SUVs in its lineup, and the Sequoia is the largest. It is priced lower than the luxurious Land Cruiser and higher than the midsize 4Runner, which is being redesigned for 2003.
 

For 2003, dual power sliding doors are available for the LE edition of Toyota's front-wheel-drive minivan, and the CE can have a right-side power door. The CE also gains optional, second-row captain's chairs, which were previously unavailable for this model. Side-impact airbags, Toyota's electronic stability system and a rear-seat video entertainment system remain available.
 

Toyota's smaller pickup truck earns standard antilock brakes for the 2003 model year. On the safety front, lower anchors have been installed for a child-safety seat.
 

When it emerged for the 2000 model year, Toyota's Tundra was the first full-size Japanese-brand pickup truck. It was also the first pickup with a V-8 engine option.
