Toyota Land Cruiser 200 (1VD-FTV Diesel, 2010): Battery and Terminal Inspection and Replacement
The diesel Land Cruiser 200 has two 12 V batteries, one on each side of the engine bay. They are wired in parallel and provide a combined 12 V. If one battery weakens, it drags the other one down, so it is best to test and replace both, or at least make sure they are the same age and in the same condition.
Parts
2- 🔩 Two 12 V batteries. The diesel Land Cruiser 200 comes with a pair of batteries connected in parallel. Choose replacements by the size and terminal polarity of the original batteries
- 🔩 capacity is usually 70-90 Ah, with cold cranking amps no lower than the original. If needed: battery terminals and the battery-to-battery jumper cable assembly (depending on condition)

Step by step
12 steps- Shut off the engine, remove the key and wait 5-10 minutes. Open the hood and locate both batteries on the left and right sides of the engine bay. Remove the plastic covers and terminal protective boots, if equipped.
- Inspect the batteries. The case should not be swollen or cracked, the terminals should have no white or green deposits, and there should be no electrolyte leaking. Check the manufacturing date on the case: a battery older than 4-5 years in a diesel is at risk of failing.
- Measure the voltage of each battery with a multimeter with the engine off. A healthy, fully charged battery reads about 12.6-12.8 V. A reading below 12.4 V means it is undercharged, and below 12.0 V means it is deeply discharged or faulty. A difference of more than 0.2-0.3 V between the two batteries indicates that one of them is weak.
- Test under load. While cranking the engine, the voltage should not drop below about 9.5-10 V. Then, with the engine running, check the charging voltage: the terminals should show about 13.8-14.5 V. If the charging voltage is out of range, the problem is in the alternator or wiring, not the battery.
- To replace a battery, first disconnect the negative terminal (black cable) on each battery, then the positive (red cable). Loosen the terminal nuts or bolts (usually 10 mm) and remove the terminals from the posts by gently rocking them, without hammering or yanking hard. If a terminal is stuck, use a terminal puller. Do not pry it off with a screwdriver using heavy force.
- Loosen the battery hold-down. This is usually a clamp bar or bracket on bolts (usually 10-12 mm) at the bottom or top. Remove the fasteners, take off the bar and lift out the battery, holding it by the handles or from underneath. The battery is heavy (about 15-25 kg (33-55 lb)), so lift carefully and keep it level.
- Clean the battery seat and tray of dirt, corrosion and electrolyte residue. If needed, treat with a baking soda solution, then wipe dry. Check that the hold-down bar and the vent hose (if fitted) are not damaged.
- Place the new battery in the tray, observing polarity. The positive and negative posts must be on the same side as on the old battery. Tighten the hold-down so the battery does not move, but not so much that the case deforms.
- Clean the inside of the cable terminals until bright using a brush or terminal cleaner. Inspect the cables: the braided strands should not be frayed, the insulation should not be cracked, and the conductor should not have green deposits. Replace damaged terminals or cables. Do not leave a poor connection, as it is a common cause of starting problems.
- Reconnect the terminals in reverse order: positive (red) first, then negative (black). Tighten them firmly, but without stripping or damaging the soft lead posts (moderate force is usually enough for such terminals, about 5-8 N·m (4-6 lb-ft); check the exact value in the manufacturer's service manual). The terminal must not turn on the post by hand. Apply a thin layer of terminal grease and close the protective caps.
- Check the jumper cable between the batteries and the ground wires: all connections must be clean and tight. This is important for stable operation of the diesel engine and the electronics.
- Start the engine, check the charging voltage (about 13.8-14.5 V) and make sure there are no error codes or messages on the instrument panel. After the battery is disconnected, the clock, radio (a code may be required, if equipped) and power window settings may be reset. The control units readapt on their own over several trips.
Common mistakes and warnings
- Always disconnect the negative first and reconnect it last, so you do not short the car body with a wrench. Do not allow a short circuit between the positive terminal and ground: on the diesel version with two batteries, short-circuit currents are very high. Wear gloves and safety glasses, as the electrolyte is corrosive. Do not throw old batteries in the trash; take them to a recycling point. If you replace only one battery, choose one with the same specifications as the other, otherwise the old battery will shorten the life of the new one.
