 | ▶ Go to "CHECK PCM/TCM " as below. |
 | ▶ Replace "OUTPUT SPEED SENSOR" as necessary and Go to "Verification Vehicle Repair" procedure. |
Ignition "ON" & Engine "OFF".
Connect "OUTPUT SPEED SENSOR" connector.
Install scantool and slect a SIMU-SCAN,
Simulate frequency to OUTPUT SPEED SENSOR signal circuit.
Fig 1) OUTPUT 150Hz → 134rpm
Fig 1) OUTPUT 250Hz → 222rpm
※ The values are subject to change according to vehicle model or conditions.
Is "OUTPUT SPEED SENSOR" signal value changed according to simulation frequency?
| ▶ Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or damage. Repair or replace as necessary 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 as necessary and then go to "Verification of Vehicle Repair" procedure. |
