Scotty, I purchased for my daughter a 2002 Cr-V with 26k actual miles from an elderly lady. It had some issues with the throttle position sensor, and I chose to resolve the TPS code by installing a new throttle body, got a great deal on eBay from a new Honda part. Now, I'm onto to talking another issue with the car.
The car came with a aftermarket key-less entry system that was installed at the dealer when the car was purchased in 2002. When the unlock button is depressed, the interior light comes on. However, when I try to open any door or the back hatch, none of the interior lights will illuminate. I unfastened the driver side door jamb switch, and I visually inspected the switch and checked for continuity when the switch is closed and open impedance when is was depressed. the switch looks like new, and it functioned normally. I noticed other issues that may be related:
- The door chime doesn't sound
- The emergency brake light doesn't come on in the dash when I pull the emergency brake lever.
I'm going to check fuses going to the multiplex control unit, but since the lights illuminate when the key-less remote unlocks the door, I don't think there is a bad fuse.
I'm wondering if there is multiplex control unit reset procedure. When I had purchased the car, the battery terminal was unhooked from the battery, and the battery was dead.
At this point, I'm at a loss as to what is wrong.
