Nissan Terrano 2 (R20) dashboard: decoding, repair and upgrade

Nissan Terrano II (internal designation R20) is a legendary frame SUV, released in 1993 and produced until 2006. Despite their venerable age, these machines are still in use due to their simple design and maintainability. One of the key elements of the interior is dashboard, which combines analogue hands with digital indicators. In this article we will analyze its structure, typical faults and methods of modernization.

Owners Terrano II often encounter dim backlights, non-functioning sensors or flashing lights. Some problems can be solved by replacing incandescent lamps with LED analogues, others require diagnostics of electronic modules. We have collected all the relevant information: from decoding pictograms to step-by-step repair instructions.

Explanation of indicators and symbols on the panel

Dashboard Nissan Terrano 2 equipped with 12 main indicators, some of which duplicate signals from the engine control unit. It is important to distinguish warning symbols (red/yellow) from information (green/blue). Below is a complete list with explanations:

• 🔴 Oil can with a drop - low oil pressure. It lights up when the engine starts and should go out after 2-3 seconds. If it is constantly on - turn off the engine immediately and check the oil level.
• 🔴 Battery - charging system malfunction. Most often the generator or oxidized terminals are to blame.
• 🟡 Check Engine - an error in the operation of the engine or transmission. Requires scanning OBD-II (on models since 1996).
• 🟢 Handbrake (P) — the parking brake is activated. On some versions it is duplicated with a sound signal.
• 🔵 High beam (blue lamp) — the high beam headlights are on. May not be available on earlier models.

Deserves special attention Terrano II specific indicators:

• 🟠 Thermometer with waves - engine overheating. Triggers when the coolant temperature is higher 110°C.
• 🟡 Exclamation mark in a circle — malfunction of the brake system (low fluid level or worn pads).
• 🟢 4WD — all-wheel drive is activated. On models with part-time 4WD It lights up only when the transfer case is on.

Typical instrument panel faults

Electronics Terrano II not reliable, especially after 20 years of operation. Here TOP-5 breakdownsproblems that owners face:

1. Dim or flickering backlight. The culprits are burnt-out incandescent lamps (standard size T5 or T10) or oxidized contacts on the board.
2. Speedometer/tachometer does not work. Most often the problem is speed sensor (located at the gearbox) or broken wiring.
3. Arrows stuck. Associated with wear stepper motors (on models with electronic devices) or contamination of the mechanism.
4. Instrument lights do not light up. Check the fuse F10 (10A) in the cabin and relay block R7.
5. False positives of indicators. For example, the oil light is on when the level is normal. Reason: faulty oil pressure sensor (article 22630-4M000).

Most problems can be resolved without replacing the entire panel. For example, backlight can be restored by installing LEDs, and frozen arrows — cleaning contacts or replacing stepper motors (price ~1500 rubles per piece).

How to check the oil pressure sensor?

Disconnect the connector from the sensor (located next to the oil filter) and close the contacts with a screwdriver. If the lamp on the panel goes out, the sensor is faulty.

⚠️ Attention: If the indicators on the panel light up at the same time oils, temperature And charging - this may indicate a broken timing belt. Stop immediately and check the belt!

Replacing backlight bulbs with LEDs: step-by-step instructions

Standard incandescent lamps Terrano 2 They last 3-5 years, after which they fade or burn out. Replacing them with LED analogues improves the visibility of devices and reduces the load on the on-board network. To work you will need:

• 🔧 Screwdriver with Phillips bit (size PH2).
• 🔦 Flashlight for illumination.
• 💡 LED type lamps T5 or T10 (white or green light).
• 🧲 Magnetic tweezers (for removing cartridges).

Replacement algorithm:

1. Remove the instrument panel by pulling it towards you. It is not necessary to disconnect the connectors - just provide access to the rear.
2. Turn the lamp sockets counterclockwise and remove them. B Terrano 2 6 lamps are used: 4 for illuminating the scales and 2 for indicators.
3. Install new LED lamps, observing the polarity (on some models, the “+” is marked with a red wire).
4. Check the backlight operation by connecting the battery. If the lamps blink, swap “+” and “–”.

The cost of a set of LED lamps for Terrano II — from 800 to 1500 rub. (depending on brightness and color). After replacement, it is recommended to adjust the backlight brightness using potentiometer on the back of the panel (marked with an arrow on the board).

Resetting the service interval and resetting the service counter

On some versions Nissan Terrano 2 (since 1998) installed interservice counter, which reminds you of the need for maintenance every 15,000 km. After completing the service, it must be reset manually. The method depends on the year of manufacture:

Year of manufacture	Reset method	Notes
1993–1997	No reset required (no counter)	Maintenance interval is monitored manually
1998–2000	Hold the daily mileage reset button for 5 seconds with the ignition on	The button is located under the speedometer
2001–2006	Turn on the ignition, press and hold the reset button, turn the key to the “ON” position	The display will show "00000"

If the counter does not reset:

• Check serviceability reset buttons (contacts often oxidize).
• Make sure the ignition is turned to position ON (not START).
• On models with on-board computer Diagnosis may be required via Consult-II.

⚠️ Attention: After resetting the counter on some versions Terrano 2 is also reset daily mileage. Write down its meaning in advance!

Modernization of the instrument panel: tuning and upgrade

Standard panel Terrano II looks outdated, but can be modernized without complete replacement. Popular upgrade options:

• 🔧 Digital Display Installation. Suitable screen from Nissan Almera N16 (size 2.5") with adaptation of connectors.
• 🎨 Repainting scales. Use special paint for plastic (eg Motip) and stencils.
• 💡 RGB backlight. Installed instead of standard lamps controlled via remote control (set ~3000 RUR).
• 📊 Replacing pointer instruments with electronic ones. Sensors from Toyota Hilux (reflashing required).

The most budget option - pasting the panel with carbon or aluminum film. This hides scuffs and gives a modern look. For a complete rework (with replacement of the board) you will need:

1. Buy a panel from Nissan Pathfinder R51 (fits the connectors).
2. Resolder the power connector or use an adapter.
3. Set the speedometer readings via ECU (diagnostic equipment required).

The cost of a complete panel replacement is from RUB 15,000. (used) up to 40,000 rub. (new with modifications). Please check compatibility before purchasing VIN code car.

Diagnosis of electronic faults

If the instrument panel Terrano 2 behaves inappropriately (readings are reset spontaneously, all indicators are on), the reason may lie in:

• Control unit malfunctions (ECU). Most often the capacitor fails C101 (1000 µF).
• Short circuit in the wiring. Check the harness from the panel to the fuse box (especially the wires orange And black flowers).
• Oxidation of contacts on connectors X1 And X2 (clean with alcohol or a special spray).

For diagnostics, use a multimeter in circuit test mode:

1. Disconnect the connector from the instrument panel.
2. Ring the circuits between the contacts 1-5 (food) and mass (contact 12).
3. Check the voltage at the contact 3 (must be 12V with the ignition on).

If the panel is completely dead and the fuses are intact, the problem may be ignition relay (article 25230-31U00) or main relay (article 25230-AL50A). These relays are located in a block under the steering wheel and often burn out from power surges.

FAQ: Frequently asked questions about the Nissan Terrano 2 instrument panel

Why don't the speedometer and tachometer needles work when cold?

This is a typical problem for Terrano II with age. Reasons:

1. Thickened grease in stepper motors (the solution is to disassemble and clean).
2. Oxidized contacts on the board (need to be wiped with alcohol).
3. Faulty speed sensor (check signal at contact 2 panel connector).

If the needles “awaken” after the interior has warmed up, the lubrication is to blame. Use silicone grease for plastic gears.

Can I install a panel from a Nissan Pathfinder?

Yes, but with reservations:

• Suitable panels from Pathfinder R50 (1996–2000) and R51 (2001–2004).
• You will need to resolder the connectors or use an adapter.
• On models with on-board computer needs to be reconfigured ECU.

The cost of alteration is from 5,000 rubles. (excluding panel price).

How to check the instrument panel before buying a used one?

Take your multimeter with you and follow the steps:

1. Check resistance between contacts 1 And 12 (must be 0 ohm - mass chain).
2. Connect the panel to the battery (contact 3 — «+», 12 - “–”). All lamps should light up.
3. Rotate the arrow axes - there should be no play or jamming.

If the seller refuses to check, this is a reason to be wary.

What should I do if only the backlight is on on the panel and the arrows do not move?

Most likely the problem is:

• Blown fuse F15 (10A) (responsible for the pointer drives).
• Broken wire between the panel and ECU (orange wire).
• Malfunction of the board itself (repair or replacement required).

For diagnostics, disconnect the panel connector and check the voltage at the contact 5 (must be 5V).

What backlight color is best to choose for LED lamps?

Color recommendations:

• White (6000K) — maximum brightness, but can be blinding at night.
• Green - original color for Terrano 2, less tires the eyes.
• Blue - stylish, but impairs the readability of the scales.

The best option is warm white (4300K) with a matte bulb (does not dazzle and is easy to read).
