I have a Pajero 2010. It stops in the middle of the road and coolant temperature light glows for like 5 seconds and this happens everyday while I am coming from work evening. When I diagnose this code occur U1102, what does it mean? I need help why the car stops.

Welcome to 2CarPros.

First, this specific model Mitsubishi isn't offered in the US, so my technical information is very limited. However, I can tell you there is an issue between ASTC and ECU. ASTC is the active stability and traction control. The ECU is the electronic control unit.

Between these two components, there is a power issue. The most common causes include the following:

Damaged wiring harness or connector
Automatic Transmission control module failed
Failed ASTC - ECU

_______________________________

Let me know if that helps. I could normally go further, but I have no wiring schematics for this specific vehicle.

Take care,
Joe

Welcome back:

You are very welcome. I just hope I can.

After reading through the manual, the plug is what seems to be the most common cause of is a bad connection. Check the connector for corrosion or a damaged pin. Also, take a look at the wiring to make sure the insulation isn't damaged.

Let me know.

Joe
