Open Door Indicator Light

WARNING: This page is about a different car, the 2003 Toyota Camry and 2002 Toyota Camry. However, it is still accessible from the selected car via links, so may be relevant.
  1. Check DOME fuse (7.5-amp) located in driver side junction block under left side of instrument panel. See Figure. If DOME fuse is okay, go to next step. If DOME fuse is defective, replace fuse and repair wiring harness or electrical connector(s) as necessary. See INTERIOR LIGHTS in SYSTEM WIRING DIAGRAMS article. After repairs have been made, perform confirmation test. See CONFIRMATION TEST  under SELF-DIAGNOSTIC SYSTEM.
  2. OPEN DOOR indicator light is located about center of instrument cluster, under left turn signal indicator. To check OPEN DOOR indicator light bulb circuit, turn ignition off and disconnect any door courtesy switch single-pin electrical harness connector. Using a fused jumper wire, ground Red/Green wire of front door courtesy switches or Red/White wire of rear door courtesy switches. OPEN DOOR indicator light should illuminate. If bulb illuminates, go to next step. If bulb does not illuminate, check light bulb. If light bulb is okay, go to next step. If light bulb is defective, replace light bulb. After repairs have been made, perform confirmation test. See CONFIRMATION TEST  under SELF-DIAGNOSTIC SYSTEM.
  3. Open each door and check that door courtesy light comes on when door is opened and goes off when door is closed. If any door courtesy light does not operate properly when door is opened and closed, go to next step. If door courtesy light operates properly when each door is opened and closed, go to step  8.
  4. Check suspect door courtesy switch. See DOOR COURTESY SWITCH under COMPONENT TESTS under INSTRUMENT PANELS - CAMRY article in ACCESSORIES & EQUIPMENT. If suspect door courtesy switch is okay, go to next step. If suspect door courtesy switch is defective, replace door courtesy switch. After repairs have been made, perform confirmation test. See CONFIRMATION TEST  under SELF-DIAGNOSTIC SYSTEM.
  5. Check wiring harness and electrical connectors between suspect door courtesy switch and body control ECU. See INTERIOR LIGHTS in SYSTEM WIRING DIAGRAMS article.
    • Red/Green wire between driver door courtesy switch electrical harness connector and body control ECU 12-pin electrical harness connector B8 terminal No. 1.
    • Red/Green wire between front passenger door courtesy switch electrical harness connector and body control ECU 22-pin electrical harness connector B6 terminal No. 11.
    • Red/White wire between left rear door courtesy switch electrical harness connector and 20-pin electrical harness connector 2K terminal No. 7. Electrical harness connector 2K is located on lower left front corner of driver side junction block. See Fig 1.
    • Red/White wire between right rear door courtesy switch electrical harness connector and 10-pin electrical harness connector 2S terminal No. 3. Electrical harness connector 2S is located on lower right rear corner of driver side junction block. See Fig 2.
    If wiring harness and electrical connectors are okay, go to next step. If any wiring harness or electrical connectors are defective, repair as necessary. See INTERIOR LIGHTS in SYSTEM WIRING DIAGRAMS article. After repairs have been made, perform confirmation test. See CONFIRMATION TEST  under SELF-DIAGNOSTIC SYSTEM.

  6. Check operation of illumination circuit. See appropriate INTERIOR LIGHTS/ILLUMINATION article in ACCESSORIES & EQUIPMENT. After confirming illumination circuit functions properly, go to next step.
  7. Check printed circuit board in instrument cluster for burned circuits, cracks in the circuit board or other problems which may prevent operation of OPEN DOOR indicator light. If printed circuit board is okay, go to next step. If printed circuit board is defective, replace circuit board. See INSTRUMENT CLUSTER under REMOVAL & INSTALLATION in INSTRUMENT PANELS - CAMRY article in ACCESSORIES & EQUIPMENT.
  8. Check body control ECU and instrument cluster ground circuits. See BODY COMPUTER and INSTRUMENT CLUSTER in SYSTEM WIRING DIAGRAMS article. If ground circuits are faulty, repair and retest system. If ground circuits are okay, substitute original body control ECU with a known-good unit and recheck system operation. If system operates properly, original body control ECU was defective. If system still does not operate properly, substitute original instrument cluster with a known-good unit and recheck system operation. If system operates properly, original instrument cluster was defective. If system still does not operate properly, perform body control ECU and instrument cluster pin voltage checks. See BODY CONTROL ELECTRONIC CONTROL UNIT  and INSTRUMENT CLUSTER  under PIN VOLTAGE TESTS. Check wiring harness and electrical connectors for an intermittent problem. Repair wiring harnesses or connectors as necessary. If voltage values, harnesses and connectors are okay, replace body control ECU or instrument cluster as required. After repairs have been made, perform confirmation test. See CONFIRMATION TEST  under SELF-DIAGNOSTIC SYSTEM.
