Engine warning
« on: September 13, 2020, 06:20:59 pm »
Hi All

Wondered if i could get a little help... I've tried looking all over and cannot find much info on some ODB2 errors.

I have had a 258B00 - Vacuum Pump Control - range/performance and 402362 - Stop Lamp Control (Subfault).

I have a Mazda 6 2.2L SE-L Nav 2013

Appreciate any insight you can give on these. I'm a little stumped.

Cheers
Steven

You may need a new vacuum pump:

MAZDA 6 (26/01/2012 – 21/01/2016) RECALL:
The vacuum pump may wear prematurely, meaning that in some applications where the brake pedal is pressed quickly whilst at low engine speed the servo assistance provided by the vacuum system is decreased. This could cause a momentary decrease in braking performance. Braking assistance available to the driver can be reduced.

That could trigger the subfault as there is not enough braking.

How did you scan for faults?
