Checks

Step 1-1. Analysis of complaints of the client

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

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

The questionnaire for the client (example)

Client's full name:

Model:

VIN:

Date of issue:

Date of registration:

Date of emergence of a problem:

Run:

Problem symptoms

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

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

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

Brakes do not work:

Other:

Emergence frequency

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

Conditions of emergence of a problem

The vehicle at a stop and the included ignition:

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

Vehicle speed: at acceleration / at delay / at a stop / at turn / at the movement with a constant speed / other

Condition of a surface are expensive: the paved road / not the paved road / road with a snow covering / other

Chains:

State of environment

Weather: other is clear/is cloudy / rain/snow /

Temperature: °F (°C)

Malfunction diagnostics code

First check: normal code / code of malfunction

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

Step 1-2. Confirmation of symptoms of a problem

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

Step 1-3. The Malfunction Diagnostics Code (MDC) - check, record and dumping

Execute Check of a code of diagnostics of malfunction as shown below, write down it and then dump it, having addressed the Dumping of the Malfunction Diagnostics Code (MDC) point in this Section.

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

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

Step 2. Check when driving

When you carry out an inspection when driving, choose the safe place where there is no transport and a possibility of transport incident and be very careful at test to avoid accident.

When checking conduct the vehicle at a speed of 40 km/h longer than minute and check whether there are problem symptoms (for example, uncharacteristic work of an alarm lamp of ABS).

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

Step 3. Check of a code of diagnostics of malfunction

Again check a malfunction diagnostics code, having addressed the subsection Check of the Malfunction Diagnostics Code (MDC) in this Section.

Step 4. Diagnostic table of codes of malfunction

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

Step 5. The diagnostic table in the Head the Brake system

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

Step 6. Check of periodically appearing problems

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

Step 7. Check and final confirmation

Make sure that the problem symptom disappeared, and in work of ABS there are no malfunctions. If the made repairs were connected with KDN, dump a malfunction code, execute check when 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

    Include ignition and turn on the parking brake. Check whether the alarm lamp (an alarm lamp of a brake) joined (1).
Model with folding top.
Except model with folding top.
    Release the parking brake at the included ignition and be convinced that the alarm lamp (an alarm lamp of a brake) went out. If the lamp does not die away, pass to Table E in this Chapter.

Check of an alarm lamp of ABS

 PERFORMANCE ORDER

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

Check of the malfunction diagnostics code (MDC) (with use of an alarm lamp of ABS)

 PERFORMANCE ORDER

    Using a wire (4), connect a diagnostic conclusion of "PNK" (3) of the black diagnostic socket (1) or blue diagnostic socket (5) to a conclusion of "BLK" (2) or the case.
Model with folding top.
Except model with folding top.
    Include ignition. Pay attention to a blinking of an alarm lamp of "ABS" giving KDN as shown in an example below and write down it. When more than two are stored in memory
    KDN, lamp blinking for each KDN repeats three times, starting with the smallest number KDN in the increasing order. More detailed information on KDN, cm in the Table of diagnostics of malfunctions of ABS in this Chapter.

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

A — the indicator of the voltmeter or an alarm lamp of ABS
In — time, sec.

and — high (incl.)
b — low (off)


The alarm lamp of ABS specifies only the following KDN. KDN 12 meaning that there are no faulty KDN remains in memory and KDN of history meaning the problem area noted earlier. At the current malfunction, the alarm lamp of ABS remains included and therefore KDN is not displayed.

    After completion of check, switch off ignition and disconnect an office wire from diagnostics socket.

Check of KDN (using the SUZUKI scanner)

 PERFORMANCE ORDER

    Connect the SUZUKI scanner to the socket of a data transmission channel (1). Special tool: (A) — SUZUKI scanner.
    Include ignition. Read KDN according to the instructions displayed on the SUZUKI scanner and unpack or write down it. Address the user's guide on the SUZUKI scanner for search of further information. After completion of check, switch-off the ignition switch and disconnect the SUZUKI scanner from DLC.

Dumping of the malfunction diagnostics code (MDC)

When you carry out an inspection when driving, choose the safe place where there is no transport and a possibility of transport incident, and be very careful at test to avoid accident.


 PERFORMANCE ORDER

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

Connection of a wire has to be 0.1 seconds and more.

    Turn on the OFF ignition switch and disconnect an office wire from diagnostics socket. Execute check when driving according to the Table of diagnostics of malfunctions of ABS and Check of the codes of diagnostics of malfunctions (CDM) in this Section and be convinced that the normal code (KDN 12) is displayed; but not a code of malfunction.

It is possible to dump KDN, using the SUZUKI scanner. Address the user's guide to an occasion of the procedure of dumping of KDN.
