2009–2010 Toyota Corolla CE, S, XRS Service Manual (PN RM12R0U)

This service package compiles Toyota Motor Corporation repair information organized around the 2010 Corolla manual for the AZE141 and ZRE142 series. Its foreword states that it carries forward all information from previously issued Pub. No. RM12R0U and adds production changes effective July 2009 or later. Toyota states that the repair manual is for personnel with specialized techniques and certifications; the Techstream routines, SST callouts, SRS procedures, refrigerant work, and structural-welding material assume a properly equipped shop.

• Files and document identity: 10,422 file pages across three PDFs: a 9,869-page merged master, a 482-page standalone Electrical Wiring Diagram, and a 71-page standalone body repair reference. The master already contains the latter two documents, so the set represents 9,869 unique pages. The EWD is identified as Pub. No. EM12R1U.
• Engine repair: Separate 2ZR-FE and 2AZ-FE sections cover engine removal and installation, cylinder-block and cylinder-head disassembly, inspection and reassembly, camshaft service, 2ZR-FE timing-gear work, 2AZ-FE valve-clearance adjustment, plus cooling, fuel, lubrication, intake, exhaust, starting, and emission-control systems.
• Transmission and driveline work: U341E and U250E automatic transaxle coverage reaches internal teardown, differential and oil-pump inspection, valve-body service, hydraulic and mechanical tests, manual-shifting tests, road tests, and initialization. C59 and E351 manual transaxle chapters add clutch bleeding, input/output shaft and differential repair, unit overhaul, and control-cable adjustment.
• Brake, steering, and suspension procedures: Front and rear disc brakes, rear drum brakes, master cylinder, booster, brake-fluid bleeding, ABS/TRAC/VSC fault diagnosis, brake-actuator service, yaw-rate and acceleration-sensor zero-point calibration, EPS calibration, wheel alignment, hubs, struts, suspension arms, and the rear axle beam are covered.
• Electronic diagnosis and setup: System diagrams, ECU terminal data, DTC charts, fail-safe tables, freeze-frame data, Techstream Data List/Active Tests, and circuit inspections support fault isolation. Factory setup work includes VIN writing, automatic-transaxle memory reset, TPMS transmitter registration and initialization, immobilizer/key registration, and occupant-classification calibration.
• Electrical diagrams: The 482-page EWD separates TMC-made and non-TMC configurations where applicable. Representative schematics include ABS/TRAC/VSC, 2AZ-FE and 2ZR-FE engine control, electronically controlled transmission and A/T indicator, built-in- and separate-amplifier audio/navigation, CAN multiplex communication, and smart-key/immobilizer systems, with connector-face and pin-location views.
• Collision reference: Body drawings cover the engine compartment, side and rear body openings, underbody, and front suspension crossmember using three-dimensional and two-dimensional measurement systems. The PDF also maps high- and ultra-high-strength steel, explains weld-point symbols, and identifies body-sealer, undercoating, foam, anti-rust wax, and silencer-sheet application areas.

Procedure, Diagnostic, and Specification Detail

The repair chapters combine component illustrations with removal, installation, disassembly, reassembly, inspection, adjustment, and operational checks. Specifications are organized by assembly and include torque tables, pressure and hydraulic-test data, fluid information, wear and runout limits, electrical test values, and alignment data for engine, tire-size, manufacturing-source, and XRS/non-XRS configurations.

Audio and navigation diagnosis addresses AVC-LAN communication, amplifier and receiver power circuits, GPS antenna and receiver faults, map-disc and player errors, Bluetooth initialization, noise-source identification, speaker circuits, and poor-reception complaints. Brake-control coverage distinguishes VSC and non-VSC systems, while steering, HVAC, smart-key, immobilizer, TPMS, SRS, and occupant-classification sections provide their own system diagrams and test paths.

Representative special-tool callouts include DLC3 diagnosis check wire SST 09843-18040, disc-holding tool SST 09330-00021, rear-disc piston tools SST 09960-10010 / 09963-00400, and rear-drum brake tools SST 09921-00010 and 09718-00011.

Body and Collision Scope

The 71-page body PDF concentrates on body measurements, collision-damage diagnosis, structural precautions, component-removal reference views, and corrosion-protection details. Its quarter-panel cut and weld drawings are examples used to explain the symbol system; it does not contain a complete panel-by-panel replacement chapter. Equipment removal up to the body-in-white condition and the later installation, inspection, adjustment, and final checks are expressly abbreviated, while painting is excluded. The front fenders are bolted on and require no welding.

Two repair cautions deserve attention. Toyota prohibits heat repair of high-strength body-frame parts because heat can reduce steel strength and damage the zinc corrosion coating; door side-impact beams and bumper reinforcement are also identified as non-repairable. The general repair instructions further warn that using a torque-wrench extension or SST without applying the specified correction can overtorque and damage components.
