Checks

Step 1-1. The analysis of complaints of the client

Write down problem details (malfunction, the complaint) and how it has arisen according to the client.

For this purpose it is possible to use the questionnaire, as shown more low to facilitate gathering of the information necessary for the correct analysis and diagnostics.

The questionnaire for the client (example)

ФИО the Client:

Model:

VIN:

Date of issue:

Registration date:

Date of occurrence of a problem:

Run:

Problem symptoms

The alarm lamp "ABS" works incorrectly: does not join/not it is switched off/blinks

Uncharacteristic noise at vehicle movement: from the engine, from the valve, other

The wheel is blocked at braking: the engine pump does not stop (works)

Brakes do not work:

Other:

Frequency of occurrence

Stojanno/periodically (once a day, month) / other

Conditions of occurrence of a problem

Vehicle at a stop and the included ignition:

At start: only at the first start/at each start / other

Speed of a vehicle: at acceleration/at delay/at to a stop/at turn/at movement with constant speed / other

Condition of a surface of road: paved road/not мощенная road/road with a snow covering / other

Chains:

State of environment

Weather: ясно/облачно/дождь/снег/иное

Temperature: F (C)

Code of diagnostics of malfunction

The first check: a normal code/code of malfunction

The second check after driving check: a normal code/code of malfunction

Step 1-2. Acknowledgement of symptoms of a problem

Check up, whether really in a vehicle there are those problems with which the client has marked in the Questionnaire for the client and if such symptom is found out, whether it is possible to consider as its malfunction or equipment refusal. This step should be carried out whenever possible together with the client. When alarm lamp ABS works incorrectly, pass to Tables of diagnostics of malfunctions - A, B or C.

Step 1-3. A code of diagnostics of malfunction (КДН) - check, record and dump

Execute Check of a code of diagnostics of malfunction as shown more low, write down it and then dump it, having addressed to point Dump of a code of diagnostics of malfunction (КДН) in this Section.

If the code of malfunction which has been displayed once and then is dumped, it is impossible to define to (find out) again, at ignition switch inclusion attempt to diagnose a problem on the basis of КДН, written down in this step can lead to incorrect diagnostics or is considerable it complicate. Pass to a step 2 whether to check up correctly function of self-diagnostics of the module of management ABS works.

If the code of malfunction which has been displayed once and then is dumped, it is possible to define to (find out) again, at ignition switch inclusion, pass to a step 3.

Step 2. Check at driving

When you inspect at driving, choose a safe place where there is no transport and possibility of transport incident and be very cautious at test to avoid failure.

At check conduct a vehicle for the speed of 40 km/h longer minutes and check up, whether there are problem symptoms (for example, uncharacteristic work of alarm lamp ABS).

If the malfunction code is again confirmed at ignition switch inclusion, check at the driving, described above, is not required. Pass to a step 3.

Step 3. Check of a code of diagnostics of malfunction

Again check up a code of diagnostics of malfunction, having addressed to subsection Check of a code of diagnostics of malfunction (КДН) in the given Section.

Step 4. The diagnostic table of codes of malfunction

According to the Table of diagnostics of malfunctions ABS for the codes of malfunction confirmed in in a step 3, establish a site of a cause of defect, namely - a sensor control, the switch, an assembly plait, a socket, the solenoid, the module of management ABS or other part and repair or replace faulty elements.

Step 5. The diagnostic table in the Head Brake system

Check up parts or system as which you consider as a possible cause of defect, having addressed to the Diagnostic table in the Head Brake system on the basis of the symptoms, noted a vehicle (the symptoms received at performance of steps 1-1, 1-2 and 2) and repair or replace faulty parts if the such are available.

Step 6. Check of periodically appearing problems

Check up parts where there can be problems (for example, an assembly plait, a socket and др), having addressed to Section Interrupting or weak connection in the Head the General information and a corresponding chain of codes of the malfunctions noted in steps 1-3.

Step 7. Check and a final confirmation

Be convinced that the problem symptom has disappeared, and in work ABS there are no malfunctions. If the carried out repairs have been connected with КДН, dump a malfunction code, execute check at driving and be convinced that the normal code is displayed.

Check of an alarm lamp (alarm lamp of a brake)

Carry out this check out of the blue.


 PERFORMANCE ORDER

  1. Include ignition and include a lay brake.
  2. Check up, whether the alarm lamp (an alarm lamp of a brake) (1) has joined.
Model with folding top.
Except model with folding top.
  1. Release a lay brake at the included ignition and be convinced that the alarm lamp (an alarm lamp of a brake) has gone out. If the lamp does not die away, pass to Table E in the given Chapter.

Check of alarm lamp ABS

 PERFORMANCE ORDER

  1. Include ignition.
  2. Be convinced that alarm lamp ABS (1) lights up approximately for 2 seconds and then dies away.
  3. If it is found out malfunctions, pass to Tables of diagnostics of malfunctions - A, B or C in the given Chapter.
Model with folding top.
Except model with folding top.

Check of a code of diagnostics of malfunction (КДН) (with use of alarm lamp ABS)

 PERFORMANCE ORDER

  1. Using a wire (4), connect a diagnostic conclusion "PNK" (3) black diagnostic sockets (1) or a dark blue diagnostic socket (5) to a conclusion "BLK" (2) or the case.
Model with folding top.
Except model with folding top.
  1. Include ignition.
  2. Pay attention to a blinking of an alarm lamp ABS, representing КДН, as shown in an example more low and write down it. When in memory it is stored more than two
    КДН, the blinking of a lamp for everyone КДН repeats three times, since the smallest number КДН in an increasing order.
  3. More detailed information about КДН, sm in the Table of diagnostics of malfunctions ABS in the given Chapter.

Example: when the chain of a sensor control of speed of the right forward wheel (КДН 21) is opened

A — the indicator of the voltmeter or alarm lamp ABS
In — time, сек

And — high (incl.)
b — low (off)


Alarm lamp ABS specifies only following КДН. КДН 12, meaning that is not present faulty КДН, remains in memory and КДН the stories, meaning the problem area noted earlier. At current malfunction, alarm lamp ABS remains included and consequently КДН is not displayed.

  1. After check end, switch off ignition and disconnect an office wire from diagnostics socket.

Check КДН (using scanner SUZUKI)

 PERFORMANCE ORDER

  1. Connect scanner SUZUKI to a socket of the data link (1). The special tool: (A) — scanner SUZUKI.
  1. Include ignition.
  2. Read КДН according to the instructions displayed on scanner SUZUKI, and unpack or write down it. Address to the user's guide on scanner SUZUKI for search of the further information.
  3. After check end, disconnect an ignition switch and disconnect scanner SUZUKI from DLC.

Dump of a code of diagnostics of malfunction (КДН)

When you inspect at driving, choose a safe place where there is no transport and possibility of transport incident, and be very cautious at test to avoid failure.


 PERFORMANCE ORDER

  1. After repair or replacement of faulty parts, dump all КДН, having executed the following procedure.
  2. Switch off ignition.
  1. Using a wire (4), connect a conclusion "PNK" (3) black diagnostic sockets (1) or a dark blue diagnostic socket (5) to a conclusion "BLK" (2) or to the case.
  1. Include ignitions.
  1. Repeat connection/switching-off of an office wire to a diagnostic conclusion of grounding at least 5 times within 10 seconds.

Wire connection should be 0.1 seconds and more.

  1. Include ignition switch OFF and disconnect an office wire from diagnostics socket.
  2. Execute check at driving according to the Table of diagnostics of malfunctions ABS and Check of codes of diagnostics of malfunctions (КДН) in the given Section and be convinced that the normal code (КДН 12) is displayed; instead of a malfunction code.

It is possible to dump КДН, using scanner SUZUKI. Address to the user's guide concerning procedure of dump КДН.
