Reading of codes of malfunctions of SRS

PERFORMANCE ORDER


1. Include ignition (the engine do not start).
2. Connect the diagnostic plug to the plug No. 1 of the diagnostic socket located under the lower cover of the dashboard near the console.
3. Reading of the codes which are written down in memory of the module of self-diagnostics is made by calculation of gleams of a control lamp of SRS/AIR BAG. A long gleam (1.2 c) corresponds to tens (10), short (0.3 c), - to units. So, the code 12 will look as follows: one long gleam + two short. 4. Codes are highlighted three times with intervals of 1.5 pages. Write down the only a few sequence, then switch off ignition, disconnect the diagnostic plug, analyse codes (see below) and make necessary recovery repair.

Cleaning of memory of the block of self-diagnostics

PERFORMANCE ORDER


1. Having finished works on correction debugged, repeat the procedure of reading of codes of malfunctions. 2. Make sure that ignition is included and connect the diagnostic plug A to the plug No. 1 of the diagnostic socket.
3. During highlighting of codes a control lamp at least for 3 seconds connect the plug B to the plug No. 2 of the diagnostic socket. Make sure of memory cleaning. Disconnect both plugs from the diagnostic socket.
