Corolla G 121 Ps Warning Light Problem


Recommended Posts

Forgive me guys. i am from Uganda.i own a 2002 jdm corolla G 121. am fascinated by your fora on my car. I have this problem: for 6months i have been driving with PS warning light on the dash. steering is ok though. started one evening when i was running the heater on high idle (3000-4000rpm)in the garage to warm me up abit. despite all attempted scans (DTC C1532, EMPS ECU malfunction), the code has never been cleared. it just doesn't go! Everything is perfect and i don't want someone poking around my computer. Now it's bothering me. anyone familiar? what next should i do? or rather, where should i check? thanks.

Try this.

Disconnect the power line in to the Steering motor and start the car. Let it idle for about 5 mins. Switch off. Remove the battery. Let it rest for 30 mins. Reconnect all. Start. Connect to the OBD and reset the code.

We did this to a friends car. Don't ask why or how it worked.

We tried the age old method of resetting troublesome hardware on PCs... :)

Good luck.
