DTC C1213: Abs Active Indicator Circuit Malfunction (Lumina & Monte CARLO)

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, select MISC TESTS and then LAMP TEST. Using scan tool, turn on and then flash ABS active (LOW TRAC) indicator. If indicator illuminates and flashes, go to step 21)  . If indicator does not illuminate or flash, go to next step.
  3. Turn ignition off. Turn ignition on, with engine off. If indicator illuminates and remains illuminated, go to next step. If indicator does not illuminate, go to step 7)  .
  4. Turn ignition off. Disconnect 24-pin EBCM connector C1. See EBCM/EBTCM LOCATION  under REMOVAL & INSTALLATION. Turn ignition on, with engine off. If ABS active indicator illuminates, go to step 16)  . If ABS active indicator does not illuminate, go to next step.
  5. Turn ignition off. Check EBCM connector C1 for poor terminal contact, corrosion or damage. If connector faults are present, go to step 17)  . If connector is okay, go to next step.
  6. Reconnect EBCM connector C1. Reconnect instrument cluster connector, if disconnected. Install scan tool. Turn ignition on, with engine off. Using scan tool, display DTCs. If DTC C1213 resets, go to step 20)  . If DTC C1213 does not reset, see INTERMITTENTS & POOR CONNECTIONS under DIAGNOSIS & TESTING.
  7. Turn ignition off. Turn ignition on, with engine off. Observe ABS and/or BRAKE indicators. If indicators illuminate and then go out, go to next step. If indicators does not illuminate, go to step 11)  .
  8. Turn ignition off. Disconnect EBCM connector C1. See EBCM/EBTCM LOCATION  under REMOVAL & INSTALLATION. Connect a fused jumper between ABS active indicator control circuit (Light Green wire) of EBCM connector C1 and ground. Turn ignition on, with engine off. If ABS active warning indicator illuminates, go to step 5)  . If ABS active indicator does not illuminate, go to next step.
  9. Turn ignition off. Remove jumper. Disconnect instrument cluster connector. Using DVOM, measure resistance of ABS active indicator control circuit (Light Green wire) between EBCM connector C1 and instrument cluster connector. If resistance is 0-2 ohms, go to next step. If resistance is not 0-2 ohms, go to step 18)  .
  10. Turn ignition on, with engine off. Using DVOM, measure voltage between ABS active indicator control circuit (Light Green wire) of EBCM connector C1 and ground. If voltage is 0-2 volts, diagnose instrument panel cluster. See appropriate INSTRUMENT PANELS article in ACCESSORIES & EQUIPMENT. If voltage is not 0-2 volts, go to step 19)  .
  11. Turn ignition off. Remove and check ABS indicator fuse (Fuse 39). If fuse is blown, go to next step. If fuse is okay, go to step 14)  .
  12. Using DVOM, measure resistance between instrument cluster power supply circuit (Pink wire) of fuse block and ground. If resistance is 0-2 ohms, go to next step. If resistance is not 0-2 ohms, go to step 15)  .
  13. Repair short to ground in Pink wire between fuse block and instrument cluster. After repairs, go to step 15)  .
  14. Repair open in Pink wire between fuse block and instrument cluster.
  15. Replace ABS indicator fuse with a known good fuse.
  16. Repair short to ground on Light Green wire between instrument cluster and EBCM.
  17. Repair EBCM connector C1. After repairs, go to step 6)  .
  18. Repair open or high resistance on Light Green wire between instrument cluster and EBCM.
  19. Repair short to voltage on Light Green wire between instrument cluster and EBCM.
  20. Replace EBCM.
  21. Malfunction is not currently present. An intermittent may be caused by a poor connection, rubbed through wire insulation, or a broken wire inside insulation. Scan tool LAMP TEST function can be used to command indicator on while checking for an intermittent malfunction in ABS active indicator circuitry. 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.
