Fuses and relays Opel Astra j (2010-2015) with decoding

The Opel Astra J first debuted at the motor show in Frankfurt am Main (Germany) in 2009. The production of the Opel Astra J in Russia began in 2010, respectively, it was produced here in 2010, 2011, 2012, 2013, 2014 and 2015- s years.

The Opel Astra J was presented in three body variations: hatchback (GTC, OPC), station wagon and sedan. This model could have a gasoline or diesel engine with a volume of 1.3 l CDTI, 1.4 l (A 14 XER), 1.4 l (A 14 NET, turbo), 1.6 l (A 16 XER), 1.6 l (A 16 LET, turbo) , 1.7 CDTI, 1.8 l, 2.0 l.

From our article you will learn where the fuse and relay blocks are located with their diagrams, descriptions and purposes. We especially note the washer and cigarette lighter fuses.

Interior fuse and relay box

The pre-storage unit in the Opel Astra J interior is located on the driver’s side (left) behind the glove compartment (glove compartment).

To access the fuse and relay box you must:

1. Open the box and push its right wall to the left;

2. Then remove the limiter on this wall from the hook with the edge of the socket in the instrument panel;
3. All that remains is to fold the storage compartment down and remove its hinges from the grooves in the instrument panel.

Installation locations

When creating the car, the company's designers took into account errors in the location of the mounting blocks not only of previous cars, but also of other well-known car brands. Everything is done so that the vehicle owner can easily get to the faulty part and calmly replace it with a new one. The Opel Astra j has three such seats:

• car interior;
• under the hood in the engine compartment;
• in the luggage compartment.

Block under the hood

In the engine compartment, the fuse box is located next to the battery.

To access you need:

Use a screwdriver (or your fingers) to press out the two latches and remove the protective cover.

How to replace it yourself?

To replace elements in the interior mounting block, no special tools are required. All you need is a slotted screwdriver and a set of new fuses.

Replacing fuses

Guidelines for replacing failed fuses, for example those responsible for the operation of a stove or cigarette lighter, are as follows:

1. Turn off the vehicle's ignition system.
2. Open the small folding box on the instrument panel, located near the knee of the driver's left leg.
3. Press the plastic clips located on the sides and remove the drawer body from the frame.
4. Unscrew the four slotted screws securing the frame.
5. Remove the mounting block from its place by pulling the bottom part.
6. Replace the faulty fuse. To do this, the damaged fuse element must be removed from the socket. The mounting block comes with small plastic pliers. They need to clamp the fuse body, pull it out of its seat and insert a new part.
7. Visually check the condition of the remaining fusible links.
8. Reassemble.

It is important to note that the new fuse must have the same rating as the failed one. If such a detail is missing, an element of slightly larger value can be used. Just first you need to check the working condition of the circuit; for this you should install a fuse from any other socket with the required rating. If the fuse remains intact, then a part with a higher rating should be installed instead. But at the first opportunity it should be replaced with a part with a standard rating. Since long-term use of an inappropriate fuse can lead to damage to the vehicle's electrical systems and fire. If after replacing the fuse it immediately fails, then it is necessary to find out the cause of the overload in the electrical circuit.

The process of changing fuses on more modern Opel Astra H 2008 or Opel GTC 2012 is identical to the above.

Replacing parts in the engine compartment is even simpler. To do this, you need to unfasten the plastic covers of the blocks and replace damaged fuses or relays.

Adjustment of maintenance period

How to reset the Opel Astra G (Opel Astra Classic II) service light. By year: 1998, 1999, 2000, 2001, 2002, 2003, 2004, 2005, 2006:

• The ignition is turned off.
• Press and hold the trip odometer reset button.
• Turn on the ignition one position before starting the engine.
• The INSP technical symbols will appear on the display for approximately 2 seconds.
• Hold down the trip odometer button until the display shows "- - -".

If the above procedure for resetting the Opel Astra G service indicator does not work, try this:

• Get into the car and close the door.
• Press and hold the brake pedal.
• Press and hold the trip reset button with the brake still applied.
• Turn on the ignition one position before starting the engine.
• The display will show "InSP" and under InSP it will be "- - - -".
• Continue holding the release button and the brake pedal for about 15 seconds.

At this point, InSP should flash, and then the computer will reset the mileage to 19,000 (in some cases, instead of 19,000, another number will appear, for example, 15,000 or 30,000). You can release the off button and brake pedal and the indicator will be reset.

• You can release the power off button, the indicator is now reset.

How can you reset the service interval on Opel Astra J 2009, 2010, 2011, 2012:

• Turn on the ignition one position before starting the engine.
• Press the MENU button until the vehicle information and settings menu appears on the display.
• Rotate the two arrow button located next to the MENU button up and down until the message “Oil Life Remaining” appears.
• Press and hold the SET/CLR button and press the brake pedal.
• Release the SET/CLR button and brake pedal, turn off the ignition.

The choice of service is always yours, although many motorists seek a full MOT, knowing that checking all routine aspects beforehand can ultimately improve performance and extend the life of the car. A mechanical review of features including tires, brakes, filters, and fluids can also help prevent any long-term problems from occurring and avoid unpleasant costs!

Enabling/disabling the anti-theft alarm

Inclusion

Make sure the hood and trunk lid are also locked. When the alarm is triggered, an acoustic signal is activated (3 signals from the volume sensors, a maximum of 10 signals from other sensors) and the direction indicators begin to flash. The maximum duration of the siren operation is 30 seconds, the blinking of the direction indicators continues for up to 5 minutes. During the first 10 seconds after the alarm is activated:

• LED lights up continuously: Monitoring, switch-on delay
• LED flashes: Any of the controlled locks is not locked, or the system is faulty

10 seconds after the alarm is activated:

• LED flashes: Anti-theft alarm activated
• LED lights up continuously for 1 second: Function deactivated.

Common Opel Astra ECU malfunctions

Common Opel Astra ECU malfunctions occur for the following reasons:

1. mechanical damage. The engine control unit is damaged by shocks and strong vibrations, which contribute to the appearance of microcracks in its circuits and housing;
2. sudden temperature changes, as a result of which the engine control unit itself overheats;
3. corrosion;
4. depressurization and moisture ingress into the ECU housing;
5. interference in the work of a block of people who do not have the necessary skills;
6. the so-called “lighting up” from a car with the engine running;
7. rearranging the terminals when connecting the battery;
8. turning on the starter without a connected power bus.

All of the above factors have different effects on the performance of the engine control unit. Some of them cause minor damage to the “brains” of the car, while others can instantly break the unit. Fortunately, there is still a way to prevent the complete breakdown of the unit - ECU diagnostics, which should be performed at least once a year. This is the only way to save on expensive repairs of a part or its complete replacement.

Engine immobilization system

Damage to the microchip may result in loss of the ability to start the engine! Do not allow the keys to heat up excessively, do not leave them in direct sunlight for a long time; try not to drop the keys or place heavy objects on them; Avoid exposure to moisture; carefully wipe the wet set dry with a soft cloth. No replaceable batteries are provided for the microchip; under no circumstances should you attempt to disassemble the key head on your own! Instrument panel Engine preheater indicator lamp (diesel models)

There is a possibility that the system will not recognize the code of the key located in the ignition switch if there is any other key with a built-in microchip nearby. To reliably identify the code, we recommend keeping each key in a separate keychain.
