Step Check Yes No
1 CHECK INPUT SIGNAL OF ECM. 
  1. Turn the ignition switch to ON.
  2. Place the shift lever in neutral.
  3. Measure the voltage between ECM connector and chassis ground.

Connector & terminal 
(B134) No. 5 (+) - Chassis ground (-): 
Is the voltage less than 1 V? Repair the poor contact of ECM connector. Go to step
2 CHECK HARNESS BETWEEN ECM AND NEUTRAL POSITION SWITCH CONNECTOR. 
  1. Turn the ignition switch to OFF.
  2. Disconnect the connector from ECM.
  3. Disconnect the connector from the neutral position switch.
  4. Measure the resistance of harness between ECM connector and neutral position switch connector.

Connector & terminal 
(B134) No. 5 - (B25) No. 2: 
(B134) No. 53 - (B25) No. 1: 
Is the resistance less than 1 Ω? Go to step Repair the harness and connector.
NOTE: In this case, repair the following item:
  • Open circuit in harness between ECM connector and neutral position switch connector
  • Poor contact of coupling connector
3 CHECK NEUTRAL POSITION SWITCH. 
  1. Place the shift lever in neutral.
  2. 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
