Power Steering Light

[CTScott]

I see them as 91 and 92 as well. Even in the 09 manual there is no reference to those codes.

I did notice that in the 09 one it only says to connect CG and TC (no TS) to read the codes. You might want to give that a try, just in case the three connections was a misprint in the 07 manual.

Yes, that's what I did -- just CG and TC. According to the '07 manual, connecting all three is done to read test code mode.

The P/S light went on again tonight on the way home as soon as I started the car. I stopped and checked the codes immediately -- 91 and 92 again. This got me to thinking... there are three ECU codes for connection with the ECM with DTCs unlike the others: U0073, U0105, and U0121. It also states "When two or more DTCs starting with [U] are output simultaneously, inspect the connectors and wire harness of each ECU."

I accidentally did some slight damage to the plastic white connector on A21 when I was installing cruise control recently, but I didn't think much of it. I wonder if this might be related. I'm going to double-check it.

UPDATE: I pulled A21, inspected it, pushed locking mechanism back in fully, and reattached. So far no trouble. I am going to have the dealer read the code with the intelligent tester when I take it in for the 25,000 mile service this coming week. I'll let you all know what they say -- hopefully it may help someone else with the same problem searching the boards down the line. Thanks again for all the help so far!

I haven't had any further problems with the Power Steering light since I did this. (My cruise control is still working perfectly.) I will still get the dealership to use the Intelligent Tester during my 25,000 mile service this Friday.

I went to the dealer and their response was "the intelligent tester won't help. If the light isn't on now then everything is fine." I didn't have the service manual with me, but unless I'm pretty sure that it describes how to use the intelligent tester to read the trouble codes from the Power steering ECU. Am I wrong?

It looks like once the light is off, the DTCs are all cleared.
