No crank 05 S60

I’ve had the cem ecm and key checked. I’ve checked the pins on the connectors and still nothing. I’ve scan the system and I’ve attached a picture of the scan. Any suggestions is welcomed. Thanks

You sure the battery is not to low? If it fall below a certain voltage the CEM will not let the starter crank.

Place your finger on the Starter Relay and have somebody turn the key to start position a number of times. Is the relay clicking?

Thanks for the reply. I’ve got a good hot battery with 13 volts. I’ve been working on this car for a while. When I first got it it would crank and start. But if you turned it off it would restart unless you disconnected the battery. Now it won’t crank at all. The starter relay is not getting a 12volts when the key is turned to start.

Will a bad UEM keep the car from cranking?

I'd try a new battery in the FOB.
