QuestionFollowup on the Cirrus.
Checked the fuses, found that the ABS fuse was apparently the wrong size and blown. That fixed the ABS light.
After checking the fuses, the P1490 code appeared.
Current codes are:
P700 - transmission fault
P1768 - Transmission relay stuck open
P1490 - cooling fan low speed relay
I have checked all the relays in the engine compartment fuse box by switching them with the fuel pump relay (which is obviously working, since the car runs) with no effect. TCM relay was switched as well, but I never see the relay pull in, even when the transmission is cycle through the gears (I have one relay with the top removed so I can watch the contact).
I cannot find the location of the fan relays or the other transmission relay in the books I have - would you be able to locate them in your documentation?
My questions:
1. Does your documentation confirm that the ABS fuse in the engine compartment should be 20A? (It appears that the adjacent 10A and the ABS fuse were switched - and probably have been since I bought the car. The cover says 20A for ABS).
2. Do you have a wiring diagram for the transmission circuit?
3. Does your documentation say where the Fan relays, transmission relays, and transmission control module are located?
Thanks again for all your help!! I think we are getting close :-)
AnswerHi Dec,
There are several fuses for the ABS system, but the one for the ABS relay is #2 and it is 20 amp. Fuse #1 is 10 amp and fuse #3 is 20 amp, if these are the ones you mean.
The fan relays are in the rear of the fuse/relay box under the hood, except you may not have noticed as they are a 'step-down' below the main front part of the box. The fan high and low speed fan relays are the rear-most, and in front of them is the ASD relay and starter relay, in-board and out-board, respectively.
The tcm is just in-board of the box, while the ecm is just outboard of the underhood fuse/relay box which is called the power distribution center.
