Ignition "ON" & Engine "OFF".
Disconnect "ATM Control Unit CLG01-A connector.
Connect scantool and select simulation function.
Simulate pulse out to output speed sensor (VSP1) terminal of TCM harness connector.
Fig 1) 150Hz → 495rpm
Fig 2) 340Hz → 1122rpm
※ The values are subject to change according to vehicle model or conditions
Does the value of output speed sensor change according to the simulation frequence ?
![]() | ▶ Substitute with a known-good output speed sensor and check for proper operation. If the problem is corrected, replace output speed sensor as necessary and go to "Verification of Vehicle Repair" procedure. |
![]() | ▶ Substitute with a known-good TCM/PCM and check for proper operation. If the problem is corrected, replace TCM/PCM as necessary and go to "Verification of Vehicle Repair" procedure. |
