Multiple problems with Volvo 2005

Also - ignition lock may be faulty

 

Ignition lock is OK, becouse there is power supply on instruments, VECU and other systems. Ignition lock actuate 3 relays: K1 - 15R (radio), K2 - kl15 - ignition, K3 - Body builder relay. K4 - starter enable ralay. actuated with VECU on some models, generally with Volvo D12D/D13 engine.

 

Power supply is erratic, so you don't know for sure

 

If you can pull the codes, I'd call a Volvo shop with them...You can post them here but I'd call a shop first...My truck(also a 2005 Volvo) was recently in Volvo shop and heard the SA do a little diagnosing over the phone, but he had to have the codes...Have the specs for your truck handy also...Good luck!

P.S. Having the headlights go out can be pretty scary in some places...

 

I have full code list to help drivers over the phone, becouse company I work for owns 500 trucks, Vovlo and Mercedes

 

That's awesome, can you PM your number!!?!?!?!

 

I'm off duty now

Post code here and I will help you)

P/S... I'm in Ukraine and time difference.....

 

The light module shows this code: mid216 pcid10 fmi5


Which is referring to the brake lights, but they are fully functional.

 

Have you bothered checking your battery cables yet?

 

Is is just the left taillight. May be the bulb of wrong rating is used ore LED. If you use leds dealer can reprogram LCM for LED disabling bulb failure monitoring for taillamps

Can you read engine codes?
