Test 20: Starter Lock-Out Relay Module
NOTE:
Module can be activated using HHT. Starter lock-out function is controlled by central locking system (Pneumatic System Equipment (PSE) control module). For testing of this system, see PNEUMATIC & POWER DOOR LOCK SYSTEMS article.
- Connect harness adapter and breakout box to anti-theft control module. Turn ignition off. Disconnect anti-theft control module connector. Measure resistance between terminals No. 5 and 18 at breakout box. Resistance should be 50-60 ohms. If resistance is as specified, go to next step. If resistance is not as specified, check wiring. See WIRING DIAGRAMS . If wiring is okay, check starter lock-out relay module, located behind instrument cluster. Repair as necessary.
- Measure voltage between terminals No. 4 and 18 at breakout box. Turn ignition switch to ON position. Battery voltage should exist. If battery voltage exists, go to next step. If battery voltage does not exist, check wiring. See WIRING DIAGRAMS .
- Measure voltage between ground and terminal No. 4 at starter lock-out relay module connector. Turn ignition switch to ON position. Battery voltage should exist. If battery voltage exists, go to next step. If battery voltage does not exist, check wiring. See WIRING DIAGRAMS .
- Measure voltage between terminals No. 4 and 5 at starter lock-out relay module connector. Turn ignition switch to ON position. Battery voltage should exist. If battery voltage exists, go to next step. If battery voltage does not exist, check control signal wiring (circuit No. 31 from anti-theft control module). See WIRING DIAGRAMS .
- Disconnect starter lock-out relay module connector. Using a 12-gauge jumper wire, bridge terminals No. 1 and 3 at starter lock-out relay module connector, switching ignition switch to "3" (start) position. Engine should start. If engine starts, wiring is okay at this time. If engine does not start, check wiring. See WIRING DIAGRAMS . Check starter lock-out relay module, ignition switch and starter. Repair as necessary.
