Hilux emergency call system error

Had a similar issue with my old BMW 3 Series. Sounds like the control module is acting up. Diagnostic codes pointed to a call failure and triggered the car safety warnings.

Could you share the specific diagnostic codes you saw and more details about the control module? That would really help with troubleshooting.

The exact code escapes me, but it definitely pointed to a problem within the emergency call system's control module. Given the cost of diagnosing and replacing those modules, I'd get a workshop to run a full diagnostic. Better to be sure before replacing expensive parts.

Took it to a workshop, and it was exactly as you thought: a defective plug connection. Replacing a cable fixed it. Repair cost 95€! Thanks!
