Reader question: Opel Astra J How to Count Errors?

How to reset errors

For cars with EasyTronic and manual gearboxes, this sequence of actions is relevant.

Depress the brake and gas at the same time, keeping your feet on the pedals.
Insert the key into the lock and turn on the ignition. There is no need to start the engine itself.
Wait a few seconds for the special beep to sound while keeping your feet on the pedals.

If diagnostics have previously been carried out using this method and the fault is completely eliminated, the error will no longer appear.

For automatic transmission

In the case of automatic gearboxes, the sequence of actions looks slightly different:

Insert the key into the ignition, turn it on, but do not start the engine.
Squeeze the brake and hold the pedal in this position.
Move the gearbox lever to “D” mode.
Turn off the ignition and then remove your foot from the brake.
Next, simultaneously press both pedals and hold them.
Turn the ignition back on and do not start the power unit.
Wait for the diagnostic procedure to complete while keeping your feet on the pedals.

In cars with automatic transmission, it is important to carry out the procedure so that the limit switches operate. Therefore, you need to press the gas pedal as deeply as possible so that a characteristic click appears. At the same time, apply moderate force to the brake.

Fault table

List of Opel Astra H error codes in Russian with a description of the problem and recommendations on how to “treat” it:

Combination	Symbol of the problem
R 0100, R 0101	Failure or incorrect operation of the air flow sensor. The reason may be a break or damage to the power line through which the device is connected.
R 0011	Problems with the intake camshaft timing system. If the error code is six-digit and is 001161 or 001166, then to convert it to standard form, you must discard the last two characters.
R 0014	Malfunctions of the camshaft phase shifter solenoid valves. The problem may be displayed in the form of errors 001463 or 1463. First of all, you need to check the operation of the camshaft sensor.

ABS errors

Problems with the Opel Astra H anti-lock system can be displayed in two digits.

Code	Description
16	Damage or short to ground in the control line of the valve solenoid mounted on the front left wheel. The reason may be that the winding is shorted to voltage. Code recognition is possible at speeds over 6 km/h.
17	The solenoid valve control circuit is faulty and is now affecting the device mounted on the front right wheel.
18	Rear brake circuit valve line damaged or shorted
19	Valve relay malfunction. An error is detected if the voltage level supplied to the device is more than 5 volts for 30 seconds or higher.
25	Failure or defective appearance of the gear wheel of the speed controller. Determination of this code is only possible in a situation where the speed of the wheel is 25% higher than the same indicator on other devices for two minutes or longer.
35	There is a malfunction in the return pump relay circuit. An error occurs when the response from the device takes more than 5 seconds.
37	The brake pedal switch line is damaged. Most likely, there was a break in the wire coming from the sensor.
39	Incorrect signal coming from the controller installed on the front left wheel. It is necessary to check the integrity of the sensor and cable.
41	Failure of the ABS sensor located on the left front wheel
42	Similar error, only with the controller installed on the right

55	Failure of the anti-lock control module

Malfunctions in the operation of the Opel Astra N ABS system are usually associated with poor contact of the sensors installed on the wheels.

Is it possible to detect problems in a car without specialized systems?

For Opel Astra F owners, the answer is yes! The designers have provided a self-diagnosis system for vehicle components. And anyone can carry out the so-called “paperclip” diagnostics of their car.

Diagnostic connectors installed in the Opel Astra F have two varieties:

The 10-pin connector was installed until 1996;
The 16-pin slot was installed after 1996.

The figure below shows the pinout of the 10-pin diagnostic connector for the Opel Astra F.

This figure shows the pinout of the 16-pin connector.

The slot for connection or self-diagnosis is located in the fuse box, under the steering wheel on the right.

Frequently asked questions about Opel Astra auto diagnostics via a computer or smartphone:

Let's look at the most popular questions related to Astra diagnostics.

Suitable adapters, cables and programs for service

Important:

Early Opel vehicles are equipped with an ALDL service socket. For connection with modern scanners, a special adapter cable is recommended - OPEL 10 Pin to OBD2. The cord will allow you to match the old block with the diagnostic equipment.

Decoding error codes with meanings

Combination options are different - it all depends on the chosen method. Remember that when you start the self-diagnosis mode, six-digit codes are displayed on the odometer panel. When using a personal computer with proprietary software installed – five characters. The first is a letter that allows you to determine the type of breakdown, and only then the combination is displayed.

First character

Letter characters have the following meaning:

C – the problem concerns the car suspension.
P – the transmission or gearbox is not functioning.
B – elements of the body structure are not working properly - the immobilizer, central locking, mirror folding system, power windows, and so on.
U – electronic components – additional modules or units – have failed.

Second character

The second character usually doesn’t interest us, but still:

0 – common code for OBD-II;
1 and 2 – manufacturer code;
3 – reserve/

Third character

The number in the third position determines the malfunction itself:

1.2 – elements of the fuel or air supply system have failed;
3 – the ignition is not working properly;
4 – the additional control system does not work;
5 – no idle;
6 – the electronic control unit module or the electrical circuit through which the manufacturer connected it has burned out.
7.8 – the gearbox does not function.

Resetting service intervals

On the mileage display, depending on its value (usually around 8000-10000 km), the inscription InSP appears.

IsP message on panel

This is an indication of the time until service maintenance. How to reset it? Please note that resetting the maintenance interval must be performed correctly to avoid errors in the operation of the vehicle.

Turn off the ignition.
After the daily mileage is displayed on the display, press the “reset” button.
While holding reset, turn on the ignition. Note: The reset button must be held for at least 10 seconds. The screen will first display a flashing InSP indication, then the maximum mileage.
When the inscriptions stop flashing, it indicates that the maintenance interval has been reset to its initial state.
