Monitor GDS Data

Check PCM communication
1. Ignition "ON" & Engine "OFF"
2. Connect GDS and setup the oscilloscope.
3. Back probe and measure signal waveform of Pin No. 61 (EMS COM) terminal of PCM main harness connector and chassis ground by using VMI A channel. (AT)
4. Back probe and measure signal waveform of Pin No. 83 (EMS COM) terminal of PCM main harness connector and chassis ground by using VMI A channel. (MT)
  Specification: Refer to Fig 1 below

5. Is the measured signal waveform normal?
  YES
  - Fault is intermittent caused by poor contact in Smart Key unit and/or PCM's connector or was repaired and Smart Key unit and memory was not cleared. Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or damage. Repair or replace as necessary and then go to "VERIFICATION OF REPAIR " procedure.
  NO
  - Go to "SMK Status Information" procedure.
SMK Status Information
1. Ignition "ON" & Engine "OFF"
2. Erase DTC after connecting GDS.
3. Check Smart key status in "Vehicle S/W management", if DTC is retrieved.
