Troubleshooting Hints - Brake Transaxle Shift Interlock

1. Check the BTSI PARK LOCK Fuse for an open. If the fuse is open, check for a short to ground in Circuit 1439 or 1135.
2. Check the IGN MAIN 1 Maxifuse for an open. If the maxifuse is open, check for a short to ground in circuit 42.
3. Make sure G117 is clean and tight.
^ Check for a broken (or partially broken) wire inside of the insulation which could cause system malfunction but prove GOOD in a continuity/voltage check with a system disconnected. These circuits may be intermittent or resistive when loaded, and if possible, should be checked by monitoring for a voltage drop with the system operational (under load).
^ Check for proper installation of aftermarket electronic equipment which may affect the integrity of other systems. Refer to General Troubleshooting Procedures. Diagnostic Aids
^ Refer to System Diagnosis.
