I just bought a used 03 pilot, 225000km.
There is an odd bunch of electrical issues:
DRL fault light sometimes comes on, when it does, passenger side DRL and high beam don’t work, but they work when it’s off. Recently replaced DRL relay under dash. Checked all fuses under hood, cleaned all contacts with electrical contact cleaner, cleaned battery contacts and added dielectric grease. Didn’t test DRL control module under dash. OBD code reader said oxygen sensor, catalytic converter and nothing else.
VTM-4 fault light sometimes comes on, when it does, VTM-4 doesn’t work, but works when fault light is off.
SRS fault light always on
maintenance required light always on
side airbag fault light sometimes comes on
check engine light sometimes comes on
Old owner put an aftermarket amp/speaker in, splicing in a 30 amp inline fuse to one of the hots from the battery.
What do you think is the solution?
Thank you for your time and help.
