Daewoo B13T-2, B15T-2, B18T-2 1999 Service Manual

If you’ve wasted a Saturday chasing a failure code that turned out to be a bad resistor because the aftermarket diagram had the pinout swapped, you know why I’m writing this. The Daewoo B13T-2, B15T-2, B18T-2 1999 Service Manual sitting on my bench is 451 pages of the actual factory release, not a photocopy of a photocopy. Every torque value, every diagnostic sequence, every board-level transistor measurement came straight from Daewoo’s engineering floor in May 1999. No translator’s guesswork.

MicroController Control System: Factory Logic Unit Diagnostics

The SB2077E02 section covers the entire MicroController Control System — the brain that runs the drive circuit, hydraulic pump motor, and accessory circuits. You get the full logic unit quick reference voltage check procedure, not a generic “check voltage here” note. The manual walks through the bypass circuit, current limit, and electrical braking (plugging) current test. If the onboard “Run Time” diagnostics flag a fault, you go straight to the stored error code access procedure. No flipping between three different aftermarket reprints that all disagree on fuse ratings.

Built-In Diagnostic Operation – Pull Codes Without Guesswork

You get two diagnostic modes: self diagnostics (lift truck not running) and run time diagnostics (machine in operation). Page references in the troubleshooting problem list match the exact component test procedures later in the manual. The BDI adjustment, steer angle control, and wait mode are all documented with the same precision. I’ve seen technicians replace a whole driver board because they didn’t have the thermal switch test sequence. This manual has it: thermal switch resistance check, conductor and switch continuity, even the capacitor (head) discharge procedure so you don’t get lit up.

Component Tests: The Only Way to Confirm a Bad Driver Board

Specifications include component measurements for transistors DTR1, DTR2, PTR1, contactor coil resistances, and the full control panel layout. The driver board (on-vehicle and off-vehicle) testing procedures are detailed enough that you can isolate a failed flyback diode or a shorted transistor without desoldering everything. Need to know the thermal switch specs for the control panel? They’re listed. Diode replacement instructions are in the same section, so you don’t have to hunt through three different bookmarks. The manual also includes the “Location of Control Panel Components” diagram — actual placement of every contactor and current sensor.

Electrical System Adjustments – Get the BDI and Plugging Current Right

The rapid tune-up procedure is worth the price of the manual alone. You get the accelerator control linkage adjustment, bypass dropout adjustment, current limit test and adjustment, and the electrical braking (plugging) current test and adjustment. The programmable features section shows how to activate default settings and set option features like tilt and auxiliary switch parameters. If you’ve ever had a lift truck that surges or brakes too hard, this is where you fix it. All torque specs are in imperial units — wheel mounting, brake, drive motor, final drive, and general tightening torques are listed separately.

Why OEM Factory Documentation Beats Aftermarket Reprints

Aftermarket manuals love to say “equivalent to OEM” until you torque a steering knuckle bolt to 150 ft-lb instead of the factory 85 ft-lb. This manual has the official Daewoo form numbers — SB2076E01 (safety and torque specs), SB2078E01 (power train), SB2079E01 (vehicle systems). Every page is scanned from the actual 1999 release. No reprints, no third-party “adaptations.” The wiring schematics are factory color-coded. The glossary terms match the Daewoo parts catalog. If you’re working on a B13T-2, B15T-2, or B18T-2, this is the only book you should have open on the workbench.

Who Should Use This 451-Page Manual?

Professional shop owners: Hand this to your technician when he’s diagnosing a “Run Time” fault. The troubleshooting problem list and quick diagnostic procedure cut down on bench time. DIY fleet mechanics: If you maintain a few of these buses, you need the hydraulic pump motor circuit and lift control circuit sections — they’re often skipped in cheaper manuals. Tech school instructors: Use the component test procedures as lab exercises. The transistor measurement tables and driver board test points are textbook-quality. Beginners should start with the safety warnings on page 1 (the notice about weights and lifting procedures) before touching anything.

Frequently Asked Questions

Does this manual cover the engine and transmission?

Yes. The SB2078E01 power train section covers the drive motor, final drive, brake, and transmission. It includes armature terminal tests, brush life estimate, and thermal switch tests.

Is the manual in English with imperial units?

Yes. All torque values, measurements, and specifications are in imperial units (ft-lb, inches, lb). The original 1999 release is in English with factory imperial specs. No metric conversion errors.
