Power Steering, hand brake and ABS

[pwuser155296646441]

Dear Seniors,
I have Vitz 2007. Just today when I was driving the car all of a sudden ABS, Power Steering and hand brake lights turned on for a second and disappeared. It also cutt off car's radio power supply. This happened 2 to 3 times but lights went off in seconds. Later, I checked ABS by applying hard brakes on 60 and it was working fine.
It is Eid and no mechanic is available. Would really appreciate if you can tell what could be the problem?
Regards,
Foji

Unless / until the car is properly scanned and diagnosed via OBD tool, to check for any / all fault codes, etc., I think nothing can be said with surety as to what is the problem?

For the time being, and as a desi totka, park your car on a perfectly levelled, horizontal surface, and remove the -ve terminal of the battery for at least half an hour, and reconnect. May be, the issue gets resolved.

Tighten battery terminals properly.
