Test Procedure
- Turn ignition off. Disconnect instrument cluster 12-pin harness connector "B" and ECM 81-pin harness connector. See Fig 1
and Figure
. Measure resistance between instrument cluster connector terminal B6 (Orange/Black wire) and ECM connector terminal No. 59. Resistance should be below one ohm. If resistances are as specified, go to next step. If any resistance is not as specified, repair open or short circuit as necessary and go step 4
.
- With instrument cluster and ECM harness connector disconnected. Turn ignition on. Measure voltage between ground and instrument cluster connector terminal B6 (Orange/Black wire). Voltage should be below 0.5 volts. If voltage is as specified, go to next step. If resistance is not as specified, repair short circuit as necessary and go step 4
.
- Turn ignition off. With instrument cluster and ECM harness connector disconnected. Measure voltage between ground and instrument cluster connector terminal B6 (Orange/Black wire). Voltage should be below 0.5 volts. If voltage is as specified, thoroughly check ECM and instrument cluster for loose, bent, corroded, contaminated, deteriorated or damaged connector terminals. Repair as necessary and go to next step. If voltage is not as specified, repair open or short circuit as necessary and go to next step.
- 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.
