Precautionary measures at diagnostics of malfunctions

Before verification of diagnostic information (codes of malfunctions (DTC), data of the frame of freezing, etc.) which is in memory of an electronic control unit (PCM) do not disconnect a hitch from an electronic control unit (PCM (ECM)), a battery cable from the battery, wires of grounding of an electronic control unit (PCM) from the engine or the main fuse. Such shutdown will erase information which is stored in memory of an electronic control unit (RSM).

At the car without socket for the monitor it is possible to check or erase the diagnostic information which is stored in memory of an electronic control unit (RSM) by means of the scanning SUZUKI tool (Tech-1) or the universal scanning tool. Prior to work with the scanning tool attentively study the instruction for its operation well to understand its functions and application.

Sequence order at diagnostics of malfunctions (only for the car without socket for the monitor):

If in memory there are two or more codes of malfunctions (DTC), find that code which was found by system the first in the table of codes of malfunctions (DTC), and follow the instructions specified in the table.

If there are no instructions, eliminate malfunctions of the specified codes in the following sequence:

Any codes of malfunction (DTC), except the P 0171/P 0172 codes (fuel system too poor \too rich) and the P 0400 code (malfunction in system of recirculation of the fulfilled gases (EGR)). Codes of malfunction P 0171/P 0172 (Fuel system too poor \too rich) and the P 0400 code (malfunction in system of recirculation of the fulfilled gases (EGR)).

Before check read in the Head the General information the Section of the Precautionary measure at service of electric chains and observe them during the work.

Replacement of an electronic control unit (RSM)

When replacing a serviceable electronic control unit (PCM), check the following:

The neglect such check can lead to damage of serviceable PCM.

Resistance on all relays and drives corresponds to the specified values. The sensor of mass of air (MAF), pressure sensor in the inlet pipeline (MDP), the sensor of provision of a throttle (TP) and the sensor of pressure in the fuel tank are in good shape, and a power chain of these sensors are not closed накоротко on grounding.
