Transaxle Range Switch (A/T Models)
- Switch is mounted to automatic transaxle, near shift lever mechanism. Ensure switch is adjusted properly. Switch output can be affected by improper adjustment. Measure power supply voltage to switch. Disconnect ECM and inhibitor switch connectors. Turn ignition switch to START position.
- Measure voltage between vehicle ground and inhibitor switch harness connector terminal No. 11. Inhibitor switch wire color is Black/Yellow. Voltage measured should be battery voltage. If voltage is less than battery voltage, inspect and repair power supply circuit.
- Use DVOM and measure inhibitor switch terminal input voltage. Connect ECM connector. Ensure inhibitor switch connector is disconnected. Turn ignition switch to ON position. Measure voltage between vehicle ground and inhibitor switch harness connector terminal No. 11. Inhibitor switch wire color is Black/Yellow. Voltage measured should be battery voltage. If voltage is less than battery voltage, inspect and repair input supply circuit.
- Use DVOM and measure input voltage of ECM. Turn ignition off. Disconnect ECM connector. Connect inhibitor switch connector. Ensure shift selector lever is in "P" position. Turn ignition switch to START position. Measure voltage between vehicle ground and ECM connector terminal. See ECM INHIBITOR SWITCH INPUT CIRCUIT IDENTIFICATION table. ECM input voltage should be 8 volts or greater. If voltage is within specification, circuit is okay. If voltage is less than 8 volts, inspect and repair circuit as necessary.
