Inspection Procedure

HINT:

If DTC B2342 is output, check DTC B2342 first.

1. PERFORM INITIALIZATION (SLIDING ROOF DRIVE GEAR) 
   1. Check that the sliding roof drive gear can be initialized (see INITIALIZATION  ).

      OK : 

      Sliding roof drive gear can be initialized. 

   NG: Go to step   3 

   OK: Go to step 

2. CHECK SLIDING ROOF FUNCTION 
   1. Check the AUTO operation with the switch (see INITIALIZATION  ).

      OK : 

      AUTO operation operates normally. 

   NG: REPLACE SLIDING ROOF DRIVE GEAR SUB-ASSEMBLY (SLIDING ROOF ECU) (See  DISASSEMBLY   ) 

   OK: END 

3. CHECK HARNESS AND CONNECTOR (SLIDING ROOF DRIVE GEAR - MAP LIGHT)

   1. Disconnect the X5 drive gear connector.
   2. Disconnect the X4 and X6 map light connectors.
   3. Measure the resistance according to the value(s) in the table below.

      Standard resistance

   1. Remove the map light for standard body (see REMOVAL ) or long body (see REMOVAL ).
   2. Measure the resistance according to the value(s) in the table below.

      Standard resistance 

      MAP LIGHT ASSEMBLY (SLIDING ROOF SWITCH)
      
      

      Tester Connection	Switch Condition	Specified Condition
      A-24(UP)- A-16(GND9)	TILT UP	Below 1 Ω
      A-24(UP)- A-16(GND9)	Off	10 kΩ or higher
      A-23 (DOWN) - A-16 (GND9)	TILT DOWN	Below 1 Ω
      A-23 (DOWN)- A-16 (GND9)	Off	10 kΩ or higher
      B-3 (OPN) - A-16 (GND9)	SLIDE OPEN	Below 1 Ω
      B-3 (OPN)- A-16 (GND9)	Off	10 kΩ or higher
      B-12 (CLS) - A-16 (GND9)	SLIDE CLOSE	Below 1 Ω
      B-12 (CLS) - A-16 (GND9)	Off	10 kΩ or higher

   NG: REPLACE MAP LIGHT ASSEMBLY (SLIDING ROOF SWITCH) 

   OK: REPLACE SLIDING ROOF DRIVE GEAR SUB-ASSEMBLY (SLIDING ROOF ECU) (See  DISASSEMBLY   )
