Test Procedure

  1. Turn ignition off. Disconnect ECM harness connector "B04". See Figure . Turn ignition on. Measure voltage between ground and ECM harness connector terminal B04-37 (Blue/Yellow wire). Voltage should be battery voltage. If voltage is as specified, check for poor terminal contact due to oxidation, bent or misplace connector terminal at ECM. Repair as necessary. Go to step  3 . If voltage is not as specified, go to next step.
  2. Turn ignition off. Connect ECM harness connector "B04". Turn ignition on. Check for MIL operation in instrument cluster. MIL should illuminate for 5 seconds after ignition is turned on. If MIL operation is as specified, check open or short circuit between ECM and MIL harness connectors. Repair as necessary. Go to next step. If MIL operation is not as specified, check light bulb and cluster printed circuits, replace as necessary. Go to next step.
  3. 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.
