Mitsubishi Triton 2008: Central locking issues

I drive a 2008 Mitsubishi Triton dual-cab 2.4 petrol. Because the battery went flat, I have jump-started the car a couple of times by way of pushing. Since then I have noticed the fuel and temperature gauges are not going down when I switch off the engine. The remote locking and unlocking is no longer functioning either. I have since bought a brand-new battery, but the problem stills persist. What could have gone wrong?

A lot of cars don’t like having a battery that is low on charge or being jump-started. Either of these things can cause the body computer or even the main ECU to start playing up. My guess in this case would be the body-computer which controls the dashboard functions and things like the central locking system.

Before you rush out and pay a mechanic to look at the vehicle, there are a couple of things to try. The first is to take the remote-control for the central locking and hold the button down for at least 30 seconds. Sometimes this is enough to reset the computer and return the vehicle to normal.

If that doesn’t work, get the engine up to temperature, shut it down and carefully disconnect the battery. Leave it that way for at least 30 minutes, reconnect the battery and see if that has produced a reset. You might find the car will run a bit roughly (mainly at idle) at first until the reset computer relearns a few parameters, so be careful on the first drive after trying any of this.
