Component Inspection

Output speed sensor waveform Inspection
1. Connect "A/T solenoid valve" connector and GDS to Data Link Connector (DLC).
2. Engine ON and operate Input speed sensor.
3. Measure waveform between signal of Output speed sensor harness and chassis ground.

Specification : See specification waveform








4. Is the measured waveform within specifications?





PCM/TCM Inspection
1. Ignition off & Engine Off.
2. Disconnect "ATM solenoid valve connector.
3. Connect GDS to Data Link Connector (DLC) and select Simulation mode.
4. Input specification frequency to signal of Output speed sensor by simulation mode.








Fig 1) OUTPUT 150 Hz -> 190 rpm
Fig 2) OUTPUT 250 Hz -> 316 rpm
** The values are subject to change according to vehicle model or conditions.
5. Is measured Output speed sensor value changed by Output frequency?
