My car Maruti Swift VXI (2010)is not going beyond 30Km/Hr. The service centre is saying it is due to ECM fault and it has to be replaced. Is it possible?

Smithesh,

Let me clear your doubts.

ECM do generate error codes at times due to which the vehicle goes into safe mode.
The problem is very common in western countries, however due to lesser awareness in India we are often becoming victim.

Is your Engine Check light continuously alerting with warning siren/beep, then indeed you need to check your ECM.

An ECM along with generating Fault code will also display corrective actions for the same.
Pls demand an ECM check and reset in your presence.

The vehicle will come out of safe mode and perform perfect.

However if fault persists again, pls do one basic thing, notice the alarm fault code and then decode it with service official using ECM connector and Màruti Diagnostic software.

Just a point to add, ECM failures are very rare as ECM is a very Robust unit.
It can only fail if you have ever tried to alter the OEM Settings but that too the same settings can be restored easily.


Hope that helps.

Ankit.

Thats a perfect reply Ankit.

@ Smithesh -

Some Common Symptoms when ECM may need replacement
> Check Engine Light remains on continuously - thats the first sign
> Not able to start car - despite no problem in battery, starter, alternator, spark plug etc
> Face in Unexplained sudden jerks with loss of Power at Often times

ECM Module as the name suggest is Engine Control Module. This electrical item is like the brain of Engine and does not fail in like this. As advised by Ankit - Get the Engine Diagnostic Scanning done - it should help in
