The ground cable (31/53) is on the firewall.

The ECC is held in place by tension from four band springs, two each side. My best guess is cold weather has caused the space between the springs and the frame to contract and tighten up. You might try placing a electric space heater in the cab and let everything warm up. Watch the video, you will s...

Hi, I'm wondering if when doing an engine swap on a 2000 Volvo V70XC with another 2000 V70XC it is necessary to transfer the ECU from the donor engine? It is not necessary to transfer any electronics between the two cars. If you can avoid transferring any software driven electronics between the two...

No DTC’s but the P0102 did pop back up. ECM-121D (P0102) Mass air flow (MAF) sensor. Signal too low Diagnostic trouble code (DTC) information ECM-121D Condition The engine control module (ECM) calculates the expected mass air flow. The calculation is based on a number of different parameters. The c...

The common denominator I have noticed so far is that it cuts out around the time the engine warms up to operating temp. Metal expands when it warms up. Hum .. Electrical connectors marginally loose when cold loosen up and lose contact when warmed up? It would not be the first time tightening the me...

You know how it is, the old gets set in it's way.
Sometimes putting a fire under helps. Other times it makes no change.

That would do it. It is fuse box 11E which feeds fuse box 11C, the CEM and the REM. Fuse box is Volvo part number 9162321. A new one ~$120.00 + accessories. Self service salvage yard ~15.00 for all. You don't list where you are in Georgia but, there are at least 10 cars at LQK in Fayetteville, GA th...

There are six cars at LKQ Savannah that will have that fuse box.

Look for:
2001 - 2009 S60
1999 - 2006 S80
2001 - 2007 V70
2003 - 2014 XC90

Check the electrical connector of the signal cable between the Immobilizer Control Module and the Engine Control Module (ECM). If the contacts are not good the signal can get corrupted. The Immobilizer Control Module is under the driver's side soundproofing panel and mounted on the steering column's...

Have your friend clear the codes and see what comes back. I suspect most of the codes he pulled are artifacts because CEM-6C48 will prevent the starter motor from turning over.
