Hello!

You might just have a short in the central junction box or a bad GEM or even a bad radio.
Check to be sure that fuse number 6 and 8 any voltage at the CJB with the ignition key turned off. If either of these fuses show voltage with the ignition switch turned off, remove fuse 11 and fuse 5 of the CJB to determine if either of these fuses may be back feeding voltage to either fuse 6 or 8. If voltage is still present after removal of fuses 11 and 5, remove the Grey/Yellow wire at pin 31 and the Black/Pink wire at pin 8 of the C270a CJB connection to determine if either of these circuits is back feeding voltage into the CJB causing the respective fuse to show voltage. If there is still a presence of voltage on fuse 8 or 6, replace the CJB for an internal short. If neither fuse 6 or 8 show any voltage in step 1, replace the suspect faulty replacement GEM.


Potential Causes:
Shorted Central Junction Box
Defective Generic Electronic Module (GEM)
Shorted Wiring Harness
Radio
