DTC C0267: Pump Motor Circuit Open (Except "L" & "M" Series): Diagnosis

WARNING: This page does not describe the selected car, but rather 54 other vehicles, including the 1999 Oldsmobile Bravada, 1999 GMC Yukon, 1999 GMC Suburban, 1999 GMC Sonoma, and 1999 GMC Savana Special. However, it is still accessible from the selected car via links, so may be relevant.
  1. Perform diagnostic system check. See DIAGNOSTIC SYSTEM CHECK. After performing diagnostic system check, go to next step.
  2. Turn ignition off. Disconnect 2-pin pump motor pigtail connector from EBCM. Inspect connector and wiring for damage or corrosion that could cause an open circuit between pump motor and EBCM. If connector and wiring are okay, go to next step. If connector or wiring is faulty, go to step 10)  .
  3. Check resistance between terminals No. 1 and 2 of 2-pin pump motor pigtail connector. If resistance is 0.1-0.3 ohm, go to step 15)  . If not, go to next step.
  4. Disconnect 2-pin EBCM harness connector. Inspect connector for damage or corrosion which could cause a loss of power to EBCM. If connector is okay, go to next step. If connector is faulty, go to step 9)  .
  5. Check resistance between ground and terminal No. 2 of 2-pin EBCM harness connector. If resistance is 0-2 ohms, go to next step. If not, go to step 11)  .
  6. Turn ignition switch to RUN position. Check voltage between ground and terminal No. 1 of EBCM harness connector. If voltage reading is 10 volts or greater, go to step 8)  . If not, go to next step.
  7. Check ABS fuse or fusible link. If fuse or fusible link is open, go to step 13)  . If fuse or fusible link is okay, go to step 14)  .
  8. Inspect 2-pin EBCM harness connector for poor terminal contact or corrosion. Check for open in ground circuit to EBCM. Repair as necessary. Reconnect harness connectors. Using scan tool, clear DTC. Test drive vehicle at speed greater than 10 MPH. If DTC C0267 resets as current DTC, go to step 12)  . If DTC does not reset, malfunction is intermittent. See DIAGNOSTIC AIDS .
  9. Repair 2-pin EBCM harness connector as necessary.
  10. Repair 2-pin pump motor pigtail connector or wiring.
  11. Repair open or high resistance in ground circuit to EBCM.
  12. Replace EBCM.
  13. Repair short to ground in battery circuit between underhood fuse/relay block and EBCM.
  14. Repair open or high resistance in battery circuit to EBCM.
  15. Replace BPMV assembly. After replacing assembly, perform DIAGNOSTIC SYSTEM CHECK.
