L322 2005 TD6 Error code

backinblack · Jan 25, 2019

Having cleared all the old error codes I have 3 left
SRS Battery disconnect unit high resistance. Will disconnect the battery tomorrow and check.
LCM Rain sensor. Not too bothered about this.
IKE (Instrument cluster I think) Error number BD (189). Anyone know what this is please as I can't clear it?

Cheers

Had a quick look at the SRS Battery disconnect unit high resistance fault but can't see anything obvious, does anyone know where the system monitors the resistance please?

Cheers

In the cable to the explosive charge that disconnects the battery in the event of a crash I would imagine, the same as for the airbags and seat belt pre-tensioners

Cheers @Datatek. I thought afterwards I should have tested the resistance across it. Job for during the week now.

DO NOT go near the explosive charge with an ohm meter, you risk getting a face full of explosion.

Thanks for the warning. looking at the wiring diagram if I disconnect the yellow connector to the explosive charge there should be no chance of setting it off by measuring from the +ve terminal to the main cables.
