Default 206, ECUs and Low Cost Scan Diagnostics

Has anyone any experience of using the cheap Diagnostic Scanners (Proscan etc ) ? Am having a problem with my 206 ~ cant seem to find any error codes on one of these Scan tools ~ but ECU on dashboard is also not showing faults either ~ so not sure if the ECU has failed ?

Have posted my problem (below) and pleas for assistance on the Forum ?

Would appreciate any advice on using low cost scan tools and also on my problem with the ECU many thanks - Ron

Post :

I have a Ref 2003 Peugeot 206 1.4 petrol engine with a Sagem (9646988680 / s2000A) ECU

The car starts first time and runs ok - except for a slight intermittent misfire and high emissions in the form of wisp of black smoke when it starts - this reducing but not completely going when driving. The car drives well at speed, has power, does not stall and the slight misfire is hardly noticeable when driving

I can probably resolve the emissions and misfire with new air filter, Co2 / MAP Sensor and Coil pack ~ but there is a fault with the ECU that I would appreciate some advice with

When ignition is turned on on the dashboard ECU light comes on ( which it should ) ~ The ECU light goes off when the engine starts - and stays off, even when the Co2 & Map sensors are disconnected - which is a fault which should show an ECU light on the dash board ?

So the ECU is not showing these faults ~ as ECU dash light stays off when engine is running and shows no faults indicated when connected to a diagnostic tool? Has the ECU failed ?

Many thanks Ron

Generic code readers do not always read all a cars ECU's & features

the lexia PP22000 diagbox combination seems to be the preferred method of Diagnosis ,As it is the same or similar to dealer level equipment

hope this helps

Why the need to post the same question three times.

Multiple posting the same thing is frowned upon in all forums and considered bad etiquette as the replies get split across the multiple posts. This could result in someone with a similar problem who is following one of the threads might easily miss the answer which was posted in one of the other threads.

Do a search on the forum for the Peugeot planet map. It is the one of the approved diagnostic systems on this forum and is widely used unlike generic readers. Find the guy closest to you and send him a pm.
