Honda Civic Charging System Wiring Diagram

admin — Mon, 09 Jan 2023 01:45:13 +0000

Honda Civic charging system wiring diagram for the Honda Civic 2006. This diagram applies to Honda Civic FD also known as Honda Civic Eight Generation or Honda Civic model years 2006-2011.

The main part of the Honda Civic charging system is the alternator. It generates an AC voltage in its field coils that is changed into a DC voltage by a set of rectifier diodes. The DC voltage is then fed to a voltage regulator that is controlled by the ECM/PCM (Engine Control Module/Powertrain Control Module) with the help of the ELD (Electrical Load Detector) unit. The ELD unit senses the amount of current being drained from the battery. The information from the ELD unit is then used by the ECM/PCM to alter the alternator field coil strength. This, in turn, adjusts the output voltage of the alternator to meet the current requirement of the battery and maintain the charging voltage.

Alternator Removal and Installation

Removal

One – Make sure you have the anti-theft code for the radio, or the navigation system, then write down the customer’s audio presets.

Two – Disconnect the negative cable from the battery first, then disconnect the positive cable.

Three – Remove the drive belt. Set a wrench on the drive belt auto-tensioner from above the engine, and slowly turn the wrench in the direction shown, then remove the drive belt. NOTE: This is a hydraulic type auto-tensioner; you must turn the wrench slowly.

Four – Disconnect the alternator connector (A) and BLK wire (B) from the alternator.

Five – Remove the harness connector (C) and harness clamps (D) from the alternator.

Six – Remove the alternator.

Installation

One – Install the alternator.

Two – Connect the alternator connector (A) and BLK wire (B) to the alternator.

Three – Install the harness connector (C) and harness clamp (D) to the alternator.

Four – Install the drive belt. Install the new belt in the reverse order of removal.

Five – Connect the positive cable to the battery first, then connect the negative cable.

Six – Enter the anti-theft code for the radio or navigation system, then enter the customer’s audio presets.

Seven – Set the clock.

Honda Civic Ignition System Wiring Diagram

admin — Sun, 08 Jan 2023 20:44:48 +0000

Honda Civic ignition system wiring diagram for the Honda Civic 2006. This diagram applies to Honda Civic FD also known as Honda Civic Eight Generation or Honda Civic model years 2006-2011.

The Honda Civic ignition system is composed of the ECM/PCM (Engine Control Module/Powertrain Control Module), the battery, a 15-ampere fuse, the ignition coil relay, the four (4) ignition coils, and the four (4) spark plugs.

For a complete list of available wiring diagrams, please see Honda Civic Wiring Diagram and Honda Civic 2006 Wiring Diagram

Figure 2. Location of Honda Civic Ignition System Components

Honda Civic Ignition Coil Removal

STEP 1 – Disconnect the ignition coil connectors (A), then remove the ignition coils (B).

Figure 3. How to Remove the Honda Civic Ignition Coils

STEP 2 – Install the ignition coils in the reverse order of removal.

Spark Plug Inspection

One – Inspect the electrodes and ceramic insulator.

Burned or worn electrodes may be caused by:
- Advanced ignition timing
- Loose spark plug
- Plug heat range too hot
- Insufficient cooling

Fouled plugs may be caused by:
- Retarded ignition timing
- Oil in combustion chamber
- Incorrect spark plug gap
- Plug heat range too cold
- Excessive idling/low speed running
- Clogged air cleaner element
- Deteriorated ignition coils

Figure 4. Spark Plug Inspection

Two – If the spark plug electrode is dirty or contaminated, clean the electrode with a plug cleaner.

NOTE:
Do not use a wire brush or scrape the iridium electrode since this will damage the electrode.
Use a chemical cleaner such as Carb Spray to clean contamination on the electrode.
When using a sand blaster spark plug cleaner, do not clean for more than 20 seconds to avoid damaging the electrode.

Three – Do not adjust the gap (A) of iridium tip plugs; replace the spark plug if the gap is out of specification.

Electrode Gap Standard (New): 1.0-1.1 mm (0.039-0.043 in.)

Figure 5. Spark Plug Electrode Gap

Four – Replace the plug at the specified interval or if the center electrode is rounded (A). Use only the listed spark plugs.

Figure 6. A Spark Plug with a Rounded Electrode

Five – Apply a small amount of anti-seize compound to the plug threads, and screw the plugs into the cylinder head, finger-tight. Then torque them to 25 N·m (2.5 kgf·m, 18 lbf·ft).

Honda Civic 2006 Security System Diagrams

admin — Thu, 22 Dec 2022 22:47:33 +0000

Circuit diagrams for the Honda Civic 2006 security system. The diagrams are applicable to Honda Civic FD (Eight Generation). That is, Honda Civic model year 2006-2011. The diagrams include the Keyless Entry System, the Power Door Locks, and the Security System with its Immobilizer System. These diagrams should facilitate understanding and troubleshooting of problems with the above-mentioned systems. Also, these diagrams are of great help if you intend to install or troubleshoot an installed aftermarket alarm system.

The heart of the system here is the MICU (Multiplex Integrated Control Unit). The MICU is located under the dashboard fuse/relay box. As can be seen from the diagrams, the MICU receives its inputs from different switches. It then drives several relays to activate the door actuators. Additionally, it controls the hazard lights (left turn and right turn signal lights) and the security horn.

Honda Civic 2006 Security System Power Source

Figure 1 details how the MICU receives power from the battery. The whole MICU is powered from the battery thru a 100A fuse (No. 1). From the 100A fuse, a 50A fuse powers the MICU by passing thru the ignition switch. Two sets of fuses provide continuous, unswitched power to two separate circuits. One of them, the 40A fuse (No. 4) in series with a 20A fuse (No. 25) provides power to the Lock and Unlock relays and its accompanying door actuators. The second one, a 10A fuse (No. 23) powers the Keyless Receiver Unit.

Power Door Locks (a.k.a. Central Locking System)

Figure 1 also shows how the power door lock switches are wired. There are six switches that control the door lock actuators. Four of them are shown in Figure 1 and the other two (2) are located in Figure 2. The six switches are

Driver’s Door Lock Switch
Driver’s Door Key Cylinder Switch
Driver’s Door Lock Knob Switch
Front Passenger’s Lock Knob Switch
Left Rear Lock Knob Switch
Right Rear Lock Know Switch

When installing an aftermarket car alarm system on a Honda Civic, the alarm’s central locking system is tapped (connected) on the Driver’s Door Lock Switch. Connect the aftermarket alarm’s Lock wire the BLU wire and the Lock wire to the GRY wire.

The four (4) door lock actuators that are controlled by these six (6) switches are shown in Figure 2. There is one door lock actuator for each of the four (4) doors: the driver’s door, front passenger’s door, left rear door, and the right rear door.

Keyless Entry System

In Figure 2, we can see the diagram for the Keyless Receiver Unit. This unit is responsible for receiving the Lock and Unlock signals from the fob key remote controller. The remote controller locks or unlocks the door wirelessly. At the same time, it either arms or disarms the security alarm system.

Figure 2

Security Alarm System

Another system in Figure 2 above is the security alarm system. It shows that the MICU controls the hazard lights (turn signal lights) and the security horn. If the car model has the super-locking feature, it includes another set of four (4) door lock actuators. This is detailed in Figure 3 below (inside the dotted rectangle).
