Hi,
I'm trying to diagnose a 2014 Hilux with 2TR-FE engine.
The engine just stalled, it would crank but not start again. Disconnecting the battery allowed it to start again.
But the problem keeps re-appearing. The engine will shut down and then will not start again until the negative lead is removed and replaced.
The issue seems to only happen on hot days.
I have downloaded tech stream and the vehicle has 2 active codes.
Immobilizer - B2780 - Push switch/key unlock warning switch. (The wires for the keyswitch in the ignition barrell have been cut to stop the alarm, this code is always active )
ABS/VSC - C1241 - Low battery positive voltage or abnormally high battery positive voltage.
Battery voltage on tech stream reads 13.3V with engine running.'ECU IG power Voltage' reads 'normal'
When the fault has occurred tech stream will not connect to the ECU it says 'Can Bus Check (S604-04)
There is no system found on the communication bus. It will still connect to all other modules.
After the battery lead has been removed and replaced it will find and connect to the Engine ECU again.
