Nissan Titan 2003–2015 Service & Repair Manual

First-generation (A60; 2003–2015)

Development of the Titan began in September 1999, with design work under Diane Allen. Giovanny Arroba’s TA60 exterior was chosen in late 2000, with a final production freeze in July 2001. The design language of the future truck was previewed by the 2001 Alpha T concept shown at the 2001 Detroit Auto Show, which had previously developed through November 2000.

Production began on September 21, 2003, and sales on December 1, 2003.[3][4] The Titan used Nissan’s new full-size F-Alpha platform. This new platform was shared with the Nissan Armada and Infiniti QX56 SUVs, with all three manufactured in Canton, Mississippi, United States. The first generation Titan continued without a major redesign through 2015.

Models and equipment

All models came standard with a 32-valve, 5.6-liter engine, VK56DE, which generates 317 hp (236 kW) (305 hp or 227 kW in 2004–2006 models) and 385 lb-ft (522 N⋅m) of torque. The first generation Titan came equipped with a fully boxed ladder frame and was available in either rear-wheel drive or a shift-on-the-fly four-wheel-drive system coupled with a five-speed RE505A automatic transmission. An automatic brake-limited slip (ABLS) system was available on all Titans. The first generation was available as a King Cab (extended cab) or a crew cab with a full-sized back seat, with no regular cab being offered.

The King Cab featured a 6-foot-7-inch (2.01 m) bed, while the crew cab had a 5-foot-7-inch (1.70 m) bed. In 2008, a longer wheelbase model was offered with either an 8-foot-3-inch (2.51 m) bed on the King Cab or a 7-foot-3-inch (2.21 m) bed on the crew cab. There were originally four trim levels available: the S, SV, Pro-4x, SE, and LE. The SE and LE trim was eventually replaced by the luxury SL trim. The S as the base model, the SV a mid-level model with more features, the PRO-4X was the off-road-oriented version, and the top-level SL was offered with features like 20-inch alloy wheels as standard equipment.
