Dead 197 - Electrical Issue…

[Oilydan]

My 08 197 just cut out on me. As it died it threw up ABS, Traction, Braking etc low battery voltage faults. Coasted to a stop and put on hazards. Later wouldn’t turn rose off when button pushed.

AA came and checked all fuses, tried it on jumper packs. His OBD reader powered on but could not connect to the computer. He then towed me home.

The symptoms…

Immob light flashing, press brake and then start button…..

Immob light goes solid, all check lights on except check engine. Headlamp motors make a little whirr and steering unlocks.

Starter does not engage and no solenoid clicks. No fuel pump priming.

All check lights go out. But then Braking, ESP etc faults appear on text display. Immob light still solid.

Battery fully charged, and also tried another good battery.

Jump the starter trigger wire in fuse box (which is clean and dry) and the starter engages but doesn’t fire.

My code reader does not connect to the computer. Says it is not plugged in or ignition is not on. But it is because it powers up the code reader.

TLDR ignition powers on, but no crank and no start. No power to OBD port to read. Starter motor turns ok when solenoid directly triggered.

Heeellllp!!

The UCH might be water damaged, that usually throws up weird electrical issues... The scuttle panel needs removing and drains cleaning to stop this from happening, i do it at least once a year:

The box was replaced last year and I have kept it dry since.

Have ordered a new crank sensor. Just in case. But reaching wits end.

Not a bad shout, you might need ignition on to connect to all the computers, iirc you have to put the key card in the slot and hold start/stop for 5 seconds or something like that...
