Hello, I just purchased a used 1990 ZR1 and the full power light in the center display does not come on when the valet switch is turned to full power. Can any one lead me in the right direction to getting this fixed. Thanks

Ok, so...bulbs are all good.
No ECM codes
But, the "service ride control" light does not come on at bulb check.
What about the "low tire pressure", "service LTPWS" and "check charging system" lights? Do they come on during bulb check?
YesDiagnosis over the Internet sometimes can be really hard, so I just want to confirm...
During bulb check, the "check charging system" light does come on but the "service ride control" light and the "full engine power" light do not come on.
Is that correct?
Thanks Hib, I will keep going looking for the problem, just having someone to tell you where to look is a big help. When I find a problem I will let you know.
The reason that I bought a car with so many problems is that I did not know it had problems. The check engine light was not on or any other lights. (Now I know why) I should have started on the forum asking questions before I bought a car. How do I disable the SIR system.
Again thanks and I will let you know what I find. AJ
Found the section that tells how to disable the SIR system
