How to read an electrical diagram: decoding wire symbols and colors

Schemes Nissan Note E11 made to standard JIS (Japanese Industrial Standard), where each wire has a unique color code and marking. Here are the main elements to understand:

  • 🔴 Wire colors - are always indicated in the legend. For example, B = black, W = white, R = red, L = blue. Combination LR means "blue with a red stripe".
  • 📍 Contact numbers - on the diagram are indicated by numbers in circles (for example, 1-87 for relays). On a real block, look for the same numbers.
  • ⚡ Line thickness - thin line = control signal (for example, from a button), thick line = power circuit (for example, +12V power supply).
  • 🔄 Arrows and connectors - show the direction of current and connection points (for example, C101 - connector No. 101).

An example of decoding the dashboard backlight circuit:



Провод: W (белый) → B (чёрный)


Напряжение: +12В (от предохранителя F32)


Управление: через реле R17 (контакты 85 и 86)
Designation on the diagram Decoding Example
IG1 Ignition (first key position) Starter, fuel pump circuits
B+ Constant “plus” from the battery Power supply for radio, ECU
E1 Weight (body or battery) Negative wires of sensors
CAN-H/L CAN bus (high/low signal) Connection of ABS blocks and ECU
💡

If the diagram shows a wire BR (brown), but in the car it is green - don’t panic. Nissan sometimes changed colors in different batches. The main thing is to check the circuit with a multimeter, and not focus only on the color.

Typical electrical faults Nissan Note E11 and how to diagnose them

According to statistics from service centers, most often the owners Note E11 face five problems:

  1. Cigarette lighter doesn't work - the fuse is at fault F20 (15A) or break in the wire O (orange) from the fuse box to the socket.
  2. Low beam fails - check the relay R11 (in the block under the hood) and lamps. The track on the headlight unit board often burns out.
  3. Cooling fan does not turn on - test the temperature sensor (connector E30) and relay R22.
  4. The radio is glitchy — contacts in the connector are oxidized C104 or the fuse is blown F10 (10A).
  5. Window lifter doesn't work - check the motor (wires) B And W) and the control unit in the door.

⚠️ Attention: If after replacing the low beam lamp the high beam stops working, do not rush to change the headlight unit. Most likely you have mixed up the connectors H11 (near) and HB3 (distant). On Note E11 they are located side by side and can be easily switched if installed incorrectly.

Step-by-step instructions: how to test a circuit with a multimeter

To test circuits Nissan Note E11 Any multimeter with a continuity mode (diode icon) will do. Follow this algorithm:

  1. Preparation: Disconnect the battery (remove the negative terminal). On the diagram, find the circuit number (for example, A23 - power supply to the fuel pump).
  2. Continuity to break: Connect the test leads to the ends of the wire. If resistance 0–0.5 Ohm - the chain is OK. If OL (infinity) - break.
  3. Short circuit test: One probe for the wire, the second for ground. There must be resistance >1 MOhm. Less means there is a short circuit somewhere.
  4. Voltage check: Turn on the ignition, connect the probes to the “plus” and “minus” of the circuit. For B+ there must be 12–14 V.

Example: continuity of the cooling fan power supply circuit (R22):



1. Найдите на схеме провод Y (жёлтый) от реле к вентилятору.


2. Подключите щупы к контакту 87 реле и разъёму вентилятора.


3. Если сопротивление 0 Ом — провод цел. Если нет — ищите обрыв под капотом (часто перетирается около радиатора).
What to do if the multimeter shows unstable values?

This could mean:

- Poor contact in the connector (move the wires when measuring).

- Oxidation on the ground (clean the contact on the body).

- Interference from other circuits (disconnect all consumers before checking).

Analysis of the fuse and relay box: where everything is located

B Nissan Note E11 two main blocks:

  1. Salon block — located to the left of the steering wheel, under the cover. Here are the fuses F1–F40 and relay R1–R10 (For example, R1 - starter relay, F5 - cigarette lighter).
  2. Engine compartment block - next to the battery. Contains power fuses F101–F110 and relay R11–R25 (For example, R22 — cooling fan).

⚠️ Attention: On models Note E11 2010–2013 a relay has been added to the cabin unit R9 for the system Nissan Intelligent Key. If after replacing the battery the car does not see the key, check this relay and fuse F35 (7.5A).

Relay/fuse Number Responsible for Symptoms of a problem
Starter relay R1 Power supply to starter Clicks when turning the key, but the starter does not turn
ECU fuse F15 (10A) Engine control unit power supply The engine does not start, it is on fire Check Engine
Fan relay R22 Cooling fan control Engine overheating, fan does not turn on

Repair and replacement of wiring: practical advice

If you find a break or short circuit, do not rush to replace the entire harness. In most cases it is enough:

  • 🔧 Repair wire - use heat shrink tubing and soldering (not twisting!). For Note E11 suitable wire cross section 0.5–1.0 mm².
  • 🧲 Replace connector — contacts in connectors often oxidize C101 (fuse box) and C105 (ECU). Buy a repair kit or clean the contacts WD-40.
  • 🔥 Eliminate short circuit — if the wire rubs against the body, wrap it with electrical tape and secure it with zip ties. Popular places for rubbing: under the gas pedal and near the right headlight.

⚠️ Attention: When replacing wiring in a door (for example, a window regulator), use corrugated hose — it will protect the wires from kinks. On Note E11 the original hose has a catalog number 28410-4M000.

💡

Never use strands without soldering to repair wiring - they oxidize and become a source of short circuit. This is especially dangerous in the power supply circuits of the computer and fuel pump.

CAN bus diagnostics: why it lights up Check Engine no errors

If the dashboard lights up Check Engine, but the scanner shows no errors, the problem may be CAN bus — network connecting control units. Typical symptoms:

  • 🚗 The engine runs fine, but the error does not reset.
  • 🔄 The arrows on the device “jump” or reset to zero.
  • 🎵 The radio turns on only after several attempts.

For diagnostics:

  1. Check resistance between contacts CAN-H And CAN-L in the connector C105 (ECU). Norm: 54–66 Ohm.
  2. Inspect the wires BR (brown) and W (white) for damage. They often fray under the torpedo.
  3. Disable the units one by one (ABS, climate control) - if after disabling one of them the error disappears, it is to blame.

⚠️ Attention: If the CAN bus resistance 0 ohm or >100 Ohm, this means an open or short circuit. Do not ignore the problem - this can damage the ECU (the cost of a new one is ~30,000 ₽).

FAQ: Frequently asked questions about the electrical circuit Nissan Note E11

Where is the cigarette lighter fuse located?

In the interior fuse box it is F20 (15A). If after replacement the cigarette lighter does not work again, check the wire O (orange) from the block to the socket and ground on the body.

Why doesn't the dashboard backlight work?

Most often the fuse is to blame F12 (10A) or relay R17. Also check the lamps in the dash (they often burn out) and the contacts in the connector C103.

How to check the generator without removing it?

Connect the multimeter to the battery. Start the engine and turn on the headlights. The voltage should be 13.8–14.5 V. If it is less, the generator is not charging enough; if it is more, the voltage regulator is faulty.

Can higher rated fuses be used?

No! This may cause a fire. For example, if instead F10 (10A) for the radio, put 15A, in the event of a short circuit, the wires will melt and the fuse will not work.
