2001 Cadillac Catera 6 cyl Two Wheel Drive Automatic

My wife introduced me to your website. I read the entry Dean310@Yahoo. Com made and found we had identical problems. I have taken the BPMV out of the car. I now need to know Phone#, Address, any info to see about having the EBTCM rebuilt at the very resonable price, possibly a little more, of $159.00.

All I saw was Bosch on ebay.I emailed Dean310, if I hear I will post it. Here's the info. NO ONE did what Buzzsaw suggested, the right front wheel speed sensor, he's a Caddy tech at Dealership.
DTC U2105, U2106 & U2108: CAN COMMUNICATION LOST Description Controller Area Network (CAN) is a high speed system for sharing data between Engine Control Module (ECM), Transmission Control Module (TCM) and Electronic Brake Control Module (EBCM). CAN circuit consists of a 2-wire twisted pair connecting ECM to TCM and a second twisted pair connecting ECM to EBCM. CAN circuits are monitored continuously by modules on circuit. The only requirement is that modules are in a power on mode. Each module on CAN serial data circuit learns the identity of modules on the circuit. If a module stops communicating after all module have initiated for an ignition cycle, other modules set a DTC specific for module not communicating: Ã Â Â DTC U2105 sets when communication with ECM is lost. Ã Â Â DTC U 2106 sets when communication with TCM is lost. Ã Â Â DTC U 2108 sets when communication with EBCM is lost. Besides storing DTC as both current and history, modules on CAN network take separate actions as follows: Ã Â Â Engine Control Module (ECM) will turn MIL on during second consecutive drive cycle malfunction is detected. ECM records operating conditions at time MIL is turned on and stores data as freeze frame information. Ã Â Â Transmission Control Module (TCM) turns Service Transmission Light (STL) on when first malfunction is detected. TCM sends a request to ECM to turn MIL on during second consecutive drive cycle malfunction is detected. TCM operates in DEFAULT MODE. Ã Â Â Electronic Brake Control Module (EBCM) disables Traction Control System (TCS) and turns Traction Control (TC) indicator on. Page 1 of 1 2/28/2010 .
DTC P1700: TRANSMISSION CONTROL MODULE (TCM) REQUESTED MIL Description This DTC indicates that an emissions related transmission fault has occurred. Transmission Control Module (TCM) flashes sport mode lamp when a fault occurs on certain non-emissions related TCM systems. TCM has no direct control of Malfunction Indicator Lamp (MIL), but if a transmission fault occurs that is emissions related, MIL must illuminate. TCM transmits a MIL request signal over the CAN bus to ECM and ECM will turn on MIL. This allows MIL to illuminate, even though fault was detected by TCM.
