DTC C1214: Electronic Brake Control Relay Contact Circuit Open

WARNING: This page is about a different variant/trim than selected.
  1. Perform diagnostic system check. See DIAGNOSTIC SYSTEM CHECK. After performing diagnostic system check, go to next step.
  2. Turn ignition off. Install scan tool. Turn ignition on, with engine off. Using scan tool, display DTCs. If DTC C1216 is set, go to DTC C1216. If DTC C1216 is not set, go to next step.
  3. Using scan tool, select DATA LIST. Select and observe EBCM/EBTCM battery voltage. If voltage is equal to or greater than 10 volts, go to next step. If voltage is less than 10 volts, go to step 25)  .
  4. Turn ignition off. Disconnect EBCM/EBTCM connector. See EBCM/EBTCM LOCATION  under REMOVAL & INSTALLATION. Connect a fused jumper between ABS relay control (or relay coil control) circuit (Pink wire) of EBCM/EBTCM connector and ground. Turn ignition on, with engine off. Using DVOM, measure voltage between battery input (or enable relay) circuit (Red wire) of EBCM/EBTCM connector and ground. If voltage is equal to or greater than 10 volts, go to next step. If voltage is less than 10 volts, go to step 10)  .
  5. Turn ignition off. Remove jumper. Remove electronic brake control relay. Using DVOM, measure resistance of switched battery input (or enable relay) circuit (Red wire) between electronic brake control relay connector and EBCM/EBTCM connector. If resistance is 0-2 ohms, go to next step. If resistance is not 0-2 ohms, go to step 19)  .
  6. Disconnect negative battery cable. Disconnect positive battery cable. Using DVOM, measure resistance between positive battery terminal and battery feed circuit (Red wire) of electronic brake control relay connector. If resistance is 0-2 ohms, go to next step. If resistance is not 0-2 ohms, go to step 20)  .
  7. Connect a fused jumper between electronic brake control relay terminals No. 85 and battery voltage. Connect a jumper between electronic brake control relay terminal No. 86 and ground. Using DVOM, measure resistance between electronic brake control relay terminals No. 30 and 87. If resistance is 0-2 ohms, go to next step. If resistance is not 0-2 ohms, go to step 22)  .
  8. Turn ignition off. Check EBCM/EBTCM connectors, electronic brake control relay and connector, and positive and negative battery cable terminals for poor terminal contact, corrosion or damage. If connectors and terminals are faulty, go to next step. If connectors and terminals are okay, go to step 17)  .
  9. Remove all jumpers. Reconnect EBCM/EBTCM connectors. Reconnect electronic brake control relay. Turn ignition on, with engine off. Using scan tool, display DTCs. If DTC C1214 is set as current, go to step 24)  . If DTC C1214 is not set as current, go to step 25)  .
  10. Turn ignition off. Disconnect negative battery cable. Disconnect positive battery cable. Turn ignition on. Using DVOM, measure resistance between positive battery terminal and ABS relay control (or relay coil control) circuit (Pink wire) of EBCM/EBTCM connector. If resistance is 0-95 ohms (Century, Intrigue, 1998 Lumina, 1998 Monte Carlo and Regal) or 65-95 ohms (except Century, Intrigue, 1998 Lumina, 1998 Monte Carlo and Regal), go to next step. If resistance is not 0-95 (or 65-95) ohms, go to step 14)  .
  11. Using DVOM, measure resistance between positive battery terminal and negative battery terminal. If voltage is equal to or greater than 10 volts, go to next step. If voltage is less than 10 volts, go to step 23)  .
  12. Turn ignition off. Reconnect positive battery cable. Reconnect negative battery cable. Remove electronic brake control relay. Using DVOM, measure voltage between battery feed circuit (Red wire) of electronic brake control relay connector and ground. If voltage is equal to or greater than 10 volts, go to next step. If voltage is less than 10 volts, go to step 20)  .
  13. Using DVOM, measure resistance of switched battery input (or enable relay) circuit (Red wire) between electronic brake control relay connector and EBCM/EBTCM connector. If resistance is 0-2 ohms, go to step 7)  . If resistance is not 0-2 ohms, go to step 19)  .
  14. Remove electronic brake control relay. Using DVOM, measure resistance between electronic brake control relay terminals No. 85 and 86. If resistance is 0-95 ohms (Century, Intrigue, 1998 Lumina, 1998 Monte Carlo and Regal) or 65-95 ohms (except Century, Intrigue, 1998 Lumina, 1998 Monte Carlo and Regal), go to next step. If resistance is not 0-95 (or 65-95) ohms, go to step 22)  .
  15. Using DVOM, measure resistance of ABS relay control (or relay coil control) circuit (Pink wire) between electronic brake control relay connector and EBCM/EBTCM connector. If resistance is 0-2 ohms, go to next step. If resistance is not 0-2 ohms, go to step 18)  .
  16. Using DVOM, measure resistance between positive battery terminal and ignition feed circuit (Pink or Brown wire) of electronic brake control relay connector. If resistance is 0-2 ohms, go to step 8)  . If resistance is not 0-2 ohms, go to step 21)  .
  17. Replace all faulty terminals or connectors.
  18. Repair open or high resistance in ABS relay control (or relay coil control) circuit (Pink wire) between electronic brake control relay and EBCM/EBTCM.
  19. Repair open or high resistance in switched battery input (or enable relay) circuit (Red wire) between electronic brake control relay and EBCM/EBTCM.
  20. Repair open or high resistance in battery feed circuit (Red wire) between electronic brake control relay and fuse block.
  21. Repair open or high resistance in ignition feed circuit (Pink or Brown wire) between electronic brake control relay and fuse block, or in power supply circuits from battery or ignition switch.
  22. Replace electronic brake control relay.
  23. Repair low voltage condition. See appropriate GENERATORS & REGULATORS article in STARTING & CHARGING SYSTEMS.
  24. Replace EBCM/EBTCM. See ELECTRONIC BRAKE CONTROL MODULE/ ELECTRONIC BRAKE & TRACTION CONTROL MODULE (EBCM/EBTCM)  under REMOVAL & INSTALLATION.
  25. Malfunction is not currently present. An intermittent may be caused by a poor connection, rubbed through wire insulation, or a broken wire inside insulation. Frequency of malfunction can be determined by using enhanced diagnostic function of scan tool. Check for backed out terminals, improper mating, broken locks, improperly formed or damaged terminals, poor terminal-to-wiring connections, or damaged wiring harness.

Using scan tool, check for vibration effects by performing RELAY TEST function. With RELAY TEST commanded on, lightly tap electronic brake control relay while monitoring relay voltage. If voltage changes significantly, replace electronic brake control relay. If DTC C1214 only sets when vehicle is initially started in cold ambient temperature less than -32°F (0°C), replace electronic brake control relay.
