Test Procedure

  1. Turn ignition off. Disconnect ECM harness connector "B". See Figure . Turn ignition on. Measure voltage between ground and ECM connector terminal B20 (Red/Black wire). Voltage should be battery voltage. If voltage is as specified, check for poor, loose, damaged and corroded terminals at ECM connectors. Repair as necessary and go to step  4 . If voltage is not as specified, go to next step.
  2. Turn ignition off. Locate fuses in engine compartment fuse/relay box. See Figure . Check fuses condition. Also check ignition switch and related voltage supply circuits. See ENGINE PERFORMANCE under SORENTO in WIRING DIAGRAMS article. If fuses, ignition switch and circuits are okay, go to next step. If fuses, ignition switch or circuits are faulty, repair or replace as necessary, and go to step  4 .
  3. Temporarily install a known good ECM and check for proper operation. If problem is corrected, replace ECM and go to next step.
  4. After repair, return vehicle to original condition. Clear codes using Hi-Scan Pro/Kia Data Pro Scan tool or equivalent. Verify repairs by driving vehicle and monitoring for pending codes. If DTC is set during test drive, follow appropriate DTC test procedure.
