DIAGNOSTIC PROCEDURE

Step	Check	Yes	No
1 CHECK STOP LIGHT SWITCH. Depress the brake pedal.	Does the stop light turn on?	Go to step 2.	Inspect the stop light system.
2 CHECK HARNESS BETWEEN STOP LIGHT SWITCH AND INTEGRATED MODULE. Turn the ignition switch to OFF. Disconnect the integrated module and stop-light switch connector. Measure the resistance of harness between stop light switch and integrated module. Connector & terminal (B65) No. 3 - (B280) No. 9:	Is the measured value more than 1 MΩ?	Repair the open circuit in harness between integrated module and stop light switch.	Go to step 3.
3 CHECK HARNESS BETWEEN STOP LIGHT SWITCH AND INTEGRATED MODULE. Measure the resistance of harness between stop light switch and chassis ground. Connector & terminal (B65) No. 3 - Chassis ground:	Is the measured value less than 1 Ω?	Repair the short circuit in harness between integrated module and stop light switch.	Go to step 4.
4 CHECK HARNESS BETWEEN INTEGRATED MODULE AND SHIFT LOCK SOLENOID. Disconnect the shift lock solenoid connector. Measure the resistance of harness between integrated module and shift lock solenoid. Connector & terminal (B116) No. 4 - (B281) No. 9:	Is the measured value more than 1 MΩ?	Repair the open circuit in harness between integrated module and shift lock solenoid.	Go to step 5.
5 CHECK HARNESS BETWEEN INTEGRATED MODULE AND SHIFT LOCK SOLENOID. Measure the resistance of harness between shift lock solenoid and chassis ground. Connector & terminal (B116) No. 4 - Chassis ground:	Is the measured value less than 1 Ω?	Repair the short circuit in harness between integrated module and shift lock solenoid.	Go to step 6.
6 CHECK HARNESS BETWEEN SHIFT LOCK SOLENOID AND CHASSIS GROUND. Measure the resistance of harness between shift lock solenoid and chassis ground. Connector & terminal (B116) No. 5 - Chassis ground:	Is the measured value more than 1 MΩ?	Repair the open circuit in harness between shift lock solenoid and body ground.	Go to step 7.
7 CHECK SHIFT LOCK SOLENOID. Measure the resistance of shift lock solenoid connector terminals. Terminal No. 4 - No. 5:	Is the measured value within 20 - 40 Ω?	Go to step 8.	Replace the shift lock solenoid.
8 CHECK SHIFT LOCK SOLENOID. Connect the battery with shift lock solenoid connector terminal and operate solenoid. Terminal No. 4 (+) - No. 5 (-):	Does the shift lock solenoid operate properly?	Go to step 9.	Replace the shift lock solenoid.
9 CHECK POOR CONTACT.	Is there poor contact in A/T shift lock circuit?	Repair the poor contact.	Replace the integrated module.
