STEP	CHECK	YES	NO
1.CHECK TRANSMISSION TYPE.	Is the transmission type CVT-	Diagnostic Procedure with Cancel Code > 14	Diagnostic Procedure with Cancel Code > 14 (MT model)
2.CHECK INHIBITOR SWITCH CIRCUIT. 1) Turn the ignition switch to OFF. 2) Disconnect the inhibitor switch harness connector. 3) Turn the ignition switch to ON. 4) Measure the voltage between harness connector terminal and chassis ground. Connector & terminal (T7) No. 6 (+) — Chassis ground (−):	Is the voltage 10 V or more-	Diagnostic Procedure with Cancel Code > 14	• Check the fuse. • Check for open or short in the harness between inhibitor switch and ECM.
3.CHECK INHIBITOR SWITCH CIRCUIT. 1) Turn the ignition switch to OFF. 2) Disconnect the starter motor harness connector. 3) Measure the resistance between inhibitor switch harness connector terminal and starter motor. Connector & terminal (T7) No. 9 — Starter motor:	Is the resistance less than 10 --	Diagnostic Procedure with Cancel Code > 14	Repair the harness.
4.CHECK INHIBITOR SWITCH. Remove and check the inhibitor switch. Inhibitor Switch	Is the inhibitor switch working normal-	Replace the ECM. Engine Control Module (ECM) Engine Control Module (ECM)	Replace the inhibitor switch.
5.CHECK NEUTRAL POSITION SWITCH CIRCUIT. 1) Turn the ignition switch to OFF. 2) Disconnect the neutral position switch harness connector. 3) Turn the ignition switch to ON. 4) Measure the voltage between harness connector terminal and chassis ground. Connector & terminal (B25) No. 2 (+) — Chassis ground (−):	Is the voltage 10 V or more-	Diagnostic Procedure with Cancel Code > 14	Check for open or short in the harness between neutral position switch and ECM.
6.CHECK NEUTRAL POSITION SWITCH CIRCUIT. 1) Turn the ignition switch to OFF. 2) Measure resistance between harness connector terminal of neutral position switch and chassis ground. Connector & terminal (B25) No. 1 — Chassis ground:	Is the resistance less than 10 --	Diagnostic Procedure with Cancel Code > 14	Repair the harness.
7.CHECK NEUTRAL POSITION SWITCH. Remove and check the neutral position switch. Neutral Position Switch	Is the neutral position switch OK-	Replace the ECM. Replace the ECM. Engine Control Module (ECM) Engine Control Module (ECM)	Replace the neutral position switch.
