ISAT scan tool communication
| ISAT scan tool communication |
The Trionic ECM communicates with an ISAT scan tool via pin 33. Communication is two-way and thus involves both input and output signals.
The ISAT scan tool can communicate with the Trionic system with the ignition switched on and the engine running, but also for 15 minutes after the ignition has been switched off. Obviously no functions requiring current from the +15 and +54 circuits can then be activated.
