April 5, 2026: LEMON Manuals is launched! Read the announcement.

Diagnostic Procedure

  1. Turn ignition switch to LOCK position. Disconnect 32-pin EBCM harness connector. Turn ignition on. If left front solenoid is suspect, measure voltage between ground and 32-pin EBCM harness connector terminal No. 30 (Blue/White wire). If right front solenoid is suspect, measure voltage between ground and 32-pin EBCM harness connector terminal No. 29 (Red/White wire). If voltage is one volt or less, go to next step. If voltage is not one volt or less, repair short to voltage in identified circuit (Blue/White or Red/White wire). See WIRING DIAGRAMS  .
  2. Turn ignition switch to LOCK position. Disconnect suspect 2-pin front solenoid harness connector. If left front solenoid is suspect, measure resistance of Blue/White wire between 32-pin EBCM harness connector terminal No. 30 and 2-pin front solenoid harness connector terminal No. 1. If right front solenoid is suspect, measure resistance of Red/White wire between 32-pin EBCM harness connector terminal No. 29 and 2-pin front solenoid harness connector terminal No. 1. If resistance is 2 ohms or less, go to next step. If resistance is not 2 ohms or less, repair open or high resistance in identified circuit (Blue/White or Red/White wire). See WIRING DIAGRAMS  .
  3. Test suspect ABS solenoid. See ABS SOLENOID  under COMPONENT TESTS. If ABS solenoid is okay, go to next step.
  4. Measure resistance of suspect front solenoid ground circuit by measuring between ground and 2-pin front solenoid harness connector terminal No. 2 (Black wire). If resistance is 2 ohms or less, go to next step. If resistance is not 2 ohms or less, repair open or high resistance in suspect front solenoid ground circuit (Black wire). See WIRING DIAGRAMS  .
  5. Reconnect all harness connectors. Turn ignition on. Using scan tool, clear DTC. See CLEARING DIAGNOSTIC TROUBLE CODES  under DIAGNOSIS & TESTING. If DTC 76/78 resets, replace EBCM. If DTC 76/78 does not reset, system is currently functioning correctly. See INTERMITTENT OR POOR CONNECTIONS  .
