Sri-v 1.6L petrol turbo engine.
Last couple of dealer services the DIC showed "service vehicle soon" message and the cooling fan runs like a jet engine at 100% flat out even with cool engine and no a/c on right after the service. Then dealer advice was to just pump the accelerator 5 times with acc only powered then turn off and start car. That has worked for previous 2 services but now we have a problem where the message appears, then the fan runs at 100% speed for a while, cycles off for a short period then repeats over and over. Nothing showing on obdii adapter and software ie error codes, however its only cheap chineese adapter, but can read speed rpm etc.
DIC Coolant temperature seems to be nearly normal heating up to about 100C and of course not reaching 104-108 as the fan is running more often than not.
Dial coolant temp seems normal as well, not moving till 50c is reached then stabilising at about 1/2 display. Coolant level seems fine also.
Dealer cant look at car (not happy jan) for nearly 2 weeks.
Any ideas or suggestions of things to check guys? Not frightened of multimeter or in depth checking.
Very disappointed I have never been able to locate a service manual too!
