This 2004 XC-90 is for sale at a local Exxon service station.
I was told it was the wife's car and well cared for.
It's a base model. 5 cylinder (2.435 L low pressure turbo), auto without sunroof or leather
It drove quite well though it had no discernible turbo boost.
It shifted well, had clean oil on the dipstick though a few chunks of build-up on the filler cap and oil fill grille.
The AC worked just fine too.
I pulled 17 codes with my BSR-PPC reader.
There was no Check Engine Light
The CEL did light up appropriately with the start-up circuit.
Each 3 letter abbreviation is a node or module and is Volvo terminology.
I used CAPS after each code and definition for clarity.
1) ECM 2A2A - Rear HO2S bank #1 heating. I WILL CHANGE THE REAR O2 SENSOR
2) CEM 1A66 - Communication with ICM. NO IDEA WHAT ICM MEANS
3) CEM 5B01 - LH heating element. HEATING ELEMENT OF WHAT?
4) CEM 6C48 - Transponder type. KEY FOB TRANSPONDER?
5) CEM 6C49 - Steering Column Lock Module. KEY WORKED OK. THE DISABLER RING ?
6) CEM 8F2D - Windshield Wipers / wiper. WIPERS AND WASHERS WORKED OK
7) CEM 8F2E - Windshield Wipers / wiper. as above
8) ECM 4801 - TWC efficiency bank 1. WHAT IS TWC?
9) DDM 0025 - BUT 0035 REFERRED TO THE PASSENGER WINDOW
10) PDM 0025 - as above
11) UEM 0035 - reading lamp
12) UEM 0037 - reading lamp
13) UEM 0039 - General Courtesy lighting
14) UEM 0080 - Rain Sensor
15) PCM 002A - NO PCM CODES LISTED
16) PCM 002B - as above
17) PCM 0023 - as above
Any help with any of these will be much appreciated.
1) I was certain the heating element of the sensor went bad but have heard since that starting the car with it unplugged can leave a legacy code.
2) as stated, what's an ICM and where should I look?
3) LH (left hand?) heating element?
4 + 5) The fob was banged up and I heard having 2 fobs close together can trip such a code
6 + 7) The wipers and washers work. Maybe snow weight caused ghost codes?
8) TWC efficiency? no clue
9 + 10) Windows work so again, maybe ghost codes from holding a switch too long
11 - 14) I can live with these. I'll check the bulbs and throw water on the windshield. Where would the rain sensor be?
15 - 17) There were no PCM definition nor heading let alone codes listed. I did learn it means Power Control Module
Any help with these puzzlers is appreciated.
thanks George (and Kira)
