Ignition off & Engine Off.
Disconnect "ATM solenoid valve connector. .
Connect GDS to Data Link Connector(DLC) and select Simulation mode.
Input specification frequency to signal of Output speed sensor by simulation mode.
Fig 1) Output 200Hz → 198rpm
Fig 2) OOutput 300Hz → 298rpm
※ The values are subject to change according to vehicle model or conditions.
Is measured Output speed sensor value changed by Output frequency?
![]() | ▶ Substitute with a known-good Input speed sensor and then go to "Verification of Vehicle Repair" procedure |
![]() | ▶ Substitute with a known-good PCM/TCM and check for proper operation.If the problem is corrected, replace PCM/TCM and then go to "Verification of Vehicle Repair" procedure. |
