Heavy Steering

[yohoRB26]

Recently took my 32gtr to Lakeside track day, while under hard cornering the steering occasionally became very suddenly heavy( which in turn ruins your line, and doesn't exactly inspire confidence too keep pushing....). As though the power steering momentarily disappears, then it comes good after a second or so. More recently while reverse parking/tight slow corning, the steering has become ridiculously heavy. P/S fluid is good, no Hicas light appears either. Although the Hicas pump whines every 5 min or so.

This happens frequently but not all the time. So its like this~ out having fun fast cornering- SURPRISE no power steering feeling mid corner/ very hard to man handle the car off a set trajectory.

Any ideas would be great cuz while this is happening im not enjoying driving too much.

Check powersteering fluid level.

Check powersteering fluid level.

of course it was the first thing checked...

Check the hicas ecu in the boot under the parcel shelf. Make sure its plugged in properly. As this is the speed sensitive steering. Without it the steering goes 50% heavier.

Also check the power steering pressure switch

also check the fuses under the dash, my steering became heavy for a while, checked, replaced 3 fuses and all good again.

2 weeks later went heavy again, 1 fuse was blown.

easy check.

good luck.
