Shift Interlock Control Module: Testing and Inspection
1999 Acura NSX V6-3.2L DOHC (VTEC)SECTION Testing and Inspection
Control Unit Input Test:
Disconnect the 8P connector from the control unit.
Inspect the connector and socket terminals to be sure they are all making good contact.
- If the terminals are bent, loose, or corroded, repair them as necessary, and recheck the system.
- If the terminals look OK, make the following input tests at the connector.
- If a test indicates a problem, find and correct the cause, then recheck the system.
- If all the input tests prove OK, the control unit must be faulty; replace it.
NOTE: If the shift lock solenoid clicks when you step on the brake pedal with the ignition switch ON (II) (the shift lever in [P] position), the shift lock system is electronically OK. If the shift lever cannot be shifted from [P] position, see A/T Gear Position Switch Test and Automatic Transmission System.
