Default TCS No Comm .....

... Tech 2 says the same.
All the other codes have the H - are they still relevant?
Its an 03 Z with about 22k miles
The battery was completely dead this spring(i didn't disconnect it thinking i may have to move it on occasion)
Now has a new battery.
Grounds look clean and dry...
Any thoughts?

Okay here are the other Codes;
10 PCM:P 1571 HC
28 TCS:No Comm
40 BCM:B 0503 H,B 0508 H,B 2588 H,B2592 H
58 SDM 1040 HC
A0-LDCM:B 2282 H,B 2284 H,U 1064 H
A1-RDCM:B 2283 H,B 2285 H,U 1064 H
A6-SCM:B 0851 H
B0-RFA 1255 H

Thanks once again for any help men!
Dom

Clear ALL the DTCs and see what comes back... Coud be left over DTCs from the battery reconnect. Post all the DTCs that come back after clearing.

I'd clear the codes and take it it for a ride and see what comes back and then go from there.

A dead battery causes all kinds of issues, that are typically cured by a new one.

"H" means it is a HISTORY code or old code

Did you do what the others said to do? Clear codes and drive the car? Are these the codes you have after doing that? If so they indicate you still have a voltage problem of some sort since you have door voltage codes showing.

You need to check your battery connections for corrosion tightness and also check the other end of the battery negative cable where it is attached to ground to make sure it is in good condition.

Thanks for the help again Bill-checked these grounds visually and with the test light-all good-not seeing any bad fuses either!

Have you physically checked each EBTCM fuse with a METER and varfied that there is the correct voltage on each fuse??

Make sure that you read the fuses powered by RUN in ON & Start with the ignition ON and make sure that those fuses read full battery voltage!

I know this is an old post but it was very helpful my TC and ABS lights started coming on, but once and a while they didn't.

I did think it was the Traction control switch, but I was still checking things to make sure.

What I found was the ground next to the battery under the battery heat shield shown above by Bill Curlee in the second pic was super loose.

Thank you Mr Curlee you saved me quite a few hours of going crazy looking and testing.

Okay,voltage at the fuses is consistant with the battery-fuses are all good,checked all grounds and still no luck!
EBCM done?
