DIAGNOSTIC PROCEDURE

Step	Check	Yes	No
1 CHECK INPUT SIGNAL OF ECM . Turn the ignition switch to ON. Place the shift lever in neutral. Measure the voltage between ECM and chassis ground. Connector & terminal (B136) No. 35 (+) - Chassis ground (-):	Is the voltage less than 1 V?	Repair the poor contact of ECM connector.	Go to step 2 .
2 CHECK HARNESS BETWEEN ECM AND NEUTRAL POSITION SWITCH CONNECTOR . Turn the ignition switch to OFF. Disconnect the connectors from ECM and neutral position switch. Measure the resistance of harness between ECM and neutral position switch connector. Connector & terminal (B136) No. 35 - (B25) No. 2: (B136) No. 4 - (B25) No. 1:	Is the resistance less than 1 Ω?	Go to step 3 .	Repair the harness and connector. NOTE: In this case, repair the following item: Open circuit in harness between ECM and neutral position switch connector Poor contact of coupling connector
3 CHECK NEUTRAL POSITION SWITCH . Place the shift lever in neutral. Measure the resistance between neutral position switch terminals. Terminals No. 1 - No. 2:	Is the resistance less than 1 Ω?	Repair the poor contact of neutral position switch connector.	Replace the neutral position switch. Ref. to SWITCHES AND HARNESS .
