"V" Body (Catera)
NOTE:
Before performing the following test, check for mechanical binding or foreign material that may be preventing BTSI solenoid from operating correctly.
- Disconnect in-line 9-pin connector C205, located on gearshift lever control base, to right of gearshift lever. Turn ignition switch to ON position. Measure voltage between female side of in-line connector C205 terminal No. 8 and ground while applying brake pedal. See Figure. If battery voltage is present, go to step 3. If battery voltage is not present, go to next step.
- Check for open circuits or high resistance between connector C205 terminal No. 8 and CLAMP 15 A/T FUSE No. 2 (10-amp). Repair as necessary, then go to step 6. See WIRING DIAGRAMS . If circuits are okay, replace brakelight switch, then go to step 6.
- Measure resistance between female side of in-line connector C205 terminal No. 6 and ground. See Figure. If resistance is less than 2 ohms, go to next step. If resistance is 2 ohms or more, check for open or high resistance in circuit between in-line connector C205 terminal No. 6 and splice S200 located near instrument cluster connector branch off. Repair as necessary, then go to step 6. See WIRING DIAGRAMS .
- Measure resistance between in-line connector C205 terminals No. 6 and 7. See Figure. If resistance is 2 ohms or more, go to next step. If resistance is less than 2 ohms, check for open, faulty diode or high resistance in circuits between in-line connector C205 terminal No. 7 and automatic transmission shift lock control solenoid. See WIRING DIAGRAMS . Repair as necessary, then go to step 6. If circuits are okay, replace automatic transmission shift lock control solenoid, then go to step 6.
- Check for open circuits or high resistance between in-line connector C205 terminal No. 7, automatic transmission shift lock control switch and in-line connector C205 terminal No. 6. See WIRING DIAGRAMS . Repair as necessary, then go to next step. If circuits are okay, replace automatic transmission shift lock control switch, then go to next step.
- Ensure all components disconnected or removed during testing are reconnected and installed on vehicle. Ensure BTSI system operates correctly. See SHIFT INTERLOCK SOLENOID under DESCRIPTION & OPERATION. If system does not operate correctly, repeat step 1.
