97 EBTCM & Relay Diagram?
Hello All,
I have a 97 ssei with the ABS and traction lights on. It started intermittently 3 months or so ago (sometimes it would come on when the car started, sometimes not). After 4 weeks of that both lights remain on.
I got the code scanned and it'* C1243 Brake Pump Motor Valve Stalled. I checked the fuse on the firewall and it'* good. At this time I cannot locate the relay (Haynes manual says its under the firewall fuses). I have also removed and cleaned the EBTCM connector, but I haven't removed the EBTCM from the BPMV yet because I would like to make sure I have correct voltages before I go that far.
If anybody knows the procedure or can supply the pinout diagram for the EBTCM connector I would appreciate it. Also, can this be tested while disconnected with ignition on, motor off? I am also considering baring the large red wire on the pump motor and measuring there as well. The ground to the back of the motor is good.
Thanks for any help,
