Test Procedure

  1. Turn ignition off. Disconnect ECM 81-Pin harness connector. See Figure . Turn ignition on. Measure voltage between ground and ECM connector terminal No. 12 (Pink wire). Voltage should be battery voltage. If voltage is as specified, check for poor, loose, damaged and corroded terminals at ECM connectors. Repair if 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. Check fuses condition. Also check ignition switch and related voltage supply circuits. See SPECTRA 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.
