Safety Indicator Input Test

1. Before testing the safety indicator functions, troubleshoot the multiplex integrated control system using the B-CAN System Diagnosis Test Mode A (see TROUBLESHOOTING - B-CAN SYSTEM DIAGNOSIS TEST MODE A ).

   Multiplex Integrated Control Unit

2. Remove the left kick panel (see TRIM REMOVAL/INSTALLATION - DOOR AREAS ).
3. Disconnect under-dash fuse/relay box connectors E, H, and P.

   NOTE:

   All connectors are shown from the wire side of female terminals.

4. 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, go to step 5.
5. Reconnect the connectors to the under-dash fuse/relay box, turn the ignition switch ON (II), and make these input tests at the appropriate connectors on the under-dash fuse/relay box.
   • If any test indicates a problem, find and correct the cause, then recheck the system.
   • If all the input tests prove OK, go to step 6.

     TEST CONDITION REFERENCE CHART
     

     Cavity	Wire	Test condition	Test: Desired result	Possible cause if desired result is not obtained
     E15	GRN	Driver's door open	Measure the voltage to ground: There should be less than 1 V.	Faulty driver's door switch An open in the wire
     		Driver's door closed	Measure the voltage to ground: There should be battery voltage.	Faulty driver's door switch Short to ground
     H12	LT GRN/RED	Front passenger's door open	Measure the voltage to ground: There should be less than 1 V.	Faulty front passenger's door switch An open in the wire
     		Front passenger's door closed	Measure the voltage to ground: There should be battery voltage.	Faulty front passenger's door switch Short to ground
     E14	GRN/YEL	Left rear door open	Measure the voltage to ground: There should be less than 1 V.	Faulty left rear door switch An open in the wire
     		Left rear door closed	Measure the voltage to ground: There should be battery voltage.	Faulty left rear door switch Short to ground
     H13	GRN/WHT	Right rear door open	Measure the voltage to ground: There should be less than 1 V.	Faulty right rear door switch An open in the wire
     		Right rear door closed	Measure the voltage to ground: There should be battery voltage.	Faulty right rear door switch Short to ground
     P24	BLU/BLK(1) BLU(2)	Trunk lid open	Measure the voltage to ground: There should be less than 1 V.	Poor ground (G701) Faulty trunk lid latch switch An open in the wire
     		Trunk lid closed	Measure the voltage to ground: There should be battery voltage.	Faulty trunk lid latch switch Short to ground

6. Perform the Gauge Self-diagnostic Function (see SELF-DIAGNOSTIC FUNCTION ).
   • If the indicators flash, go to step 7.
   • If the indicators do not flash, replace the gauge control module.
7. Substitute a known-good under-dash fuse/relay box and recheck the system.
   • If the symptom is gone, the multiplex integrated control unit (MICU) is faulty; replace the under-dash fuse/relay box.
   • If the symptom is still present, the gauge control module must be faulty; replace the gauge control module.
