Diagnostic Procedure

  1. Turn ignition on. Pump brake pedal. Using scan tool, select ABS TESTS, then MANUAL CONTROL function. Select LEFT FRONT MOTOR APPLY function and apply motor. Apply firm pressure on brake pedal. Select LEFT FRONT MOTOR RELEASE function and release motor. If brake pedal falls, keep firm pressure on pedal and go to next step. If brake pedal does not fall, go to step  3 .
  2. With firm pressure still applied to brake pedal, select LEFT FRONT MOTOR APPLY function on scan tool and apply motor. If brake pedal rises, system is currently functioning correctly, see DIAGNOSTIC AIDS  . If brake pedal does not rise, go to next step.
  3. Release brake pedal. Select LEFT FRONT MOTOR APPLY function on scan tool. While monitoring commanded current and feedback current on scan tool, apply motor. If feedback current is not higher than commanded current, go to next step. If feedback current is higher than commanded current, go to step  5 .
  4. Using scan tool, select ABS TESTS and perform GEAR TENSION RELIEF function. Turn ignition switch to LOCK position. Separate motor pack from hydraulic modulator. See ABS ACTUATOR ASSEMBLY (HYDRAULIC MODULATOR/MOTOR PACK)  under REMOVAL & INSTALLATION. Attempt to manually move left front hydraulic modulator gear. If gear can be rotated at least 5 full turns lock-to-lock, replace motor pack. If gear can not be rotated at least 5 full turns lock-to-lock, replace hydraulic modulator.
  5. Turn ignition switch to LOCK position. Disconnect EBCM 8-pin harness connector and motor pack 6-pin harness connector. Measure resistance between EBCM 8-pin harness connector terminals No. 1 (Light Green/Black wire) and No. 2 (Light Green wire). If resistance is infinite, reconnect all connectors. Test drive vehicle for 3 drive cycles. See CLEARING DIAGNOSTIC TROUBLE CODES  under DIAGNOSIS & TESTING. If DTC 44 resets, replace EBCM. If resistance is not infinite, repair short between Light Green and Light Green/Black wires.
