DTC B2342 Switch Failure
DESCRIPTION
This DTC is stored when the sliding roof drive gear (sliding roof ECU) detects that the SLIDE OPEN or TILT UP switch in the map light is stuck for 30 seconds or more.
DTC Code | DTC Detection Condition | Trouble Area |
B2342 | Sliding roof drive gear (sliding roof ECU) detects sliding roof switch in map light is stuck for 30 seconds or more | Sliding roof drive gear sub-assembly (Sliding roof ECU)
Map light assembly (Sliding roof switch)
Harness or connector

2.READ VALUE USING INTELLIGENT TESTER (SWITCH STATUS) |
Use the Data List to check if the sliding roof switch is functioning properly ().
Sliding RoofTester Display | Measurement Item/Range | Normal Condition | Diagnostic Note |
Down Switch Failure(Current) | Down switch failure signal (Current)/Fail or Not Fail | Fail: Sliding roof tilt down signal failure (Current) Not Fail: Sliding roof tilt down signal not fail (Current) | - |
Up Switch Failure(Current) | Up switch failure signal (Current)/Fail or Not Fail | Fail: Sliding roof tilt up signal failure (Current) Not Fail: Sliding roof tilt up signal not fail (Current) | - |
Close Switch Failure(Current) | Close switch failure signal (Current)/Fail or Not Fail | Fail: Sliding roof close signal failure (Current) Not Fail: Sliding roof close signal not fail (Current) | - |
Open Switch Failure(Current) | Open switch failure signal (Current)/Fail or Not Fail | Fail: Sliding roof open signal failure (Current) Not Fail: Sliding roof open signal not fail (Current) | - |
Down Switch Failure(Past) | Down switch failure signal (Past)/Fail or Not Fail | Fail: Sliding roof tilt down signal failure (Past) Not Fail: Sliding roof tilt down signal not fail (Past) | - |
Up Switch Failure(Past) | Up switch failure signal (Past)/Fail or Not Fail | Fail: Sliding roof tilt up signal failure (Past) Not Fail: Sliding roof tilt up signal not fail (Past) | - |
Close Switch Failure(Past) | Close switch failure signal (Past)/Fail or Not Fail | Fail: Sliding roof close signal failure (Past) Not Fail: Sliding roof close signal not fail (Past) | - |

3.INSPECT MAP LIGHT ASSEMBLY (SLIDING ROOF SWITCH) |
Measure the resistance according to the value(s) in the table below.
- Standard Resistance:
Tester Connection | Switch Condition | Specified Condition |
19 (UP) - 17 (GND9) | UP switch is pressed | Below 1 Ω |
19 (UP) - 17 (GND9) | UP switch is not pressed | 10 kΩ or higher |
18 (DOWN) - 17 (GND9) | DOWN switch is pressed | Below 1 Ω |
18 (DOWN) - 17 (GND9) | DOWN switch is not pressed | 10 kΩ or higher |
8 (OPN) - 17 (GND9) | OPEN switch is pressed | Below 1 Ω |
8 (OPN) - 17 (GND9) | OPEN switch is not pressed | 10 kΩ or higher |
7 (CLS) - 17 (GND9) | CLOSE switch is pressed | Below 1 Ω |
7 (CLS) - 17 (GND9) | CLOSE switch is not pressed | 10 kΩ or higher |
| REPLACE MAP LIGHT ASSEMBLY (SLIDING ROOF SWITCH) ()
|

4.CHECK HARNESS AND CONNECTOR (SLIDING ROOF DRIVE GEAR - MAP LIGHT) |
Disconnect the R5 drive gear connector.
Disconnect the R7 map light connector.
Measure the resistance according to the value(s) in the table below.
- Standard Resistance:
Tester Connection | Condition | Specified Condition |
R5-10 (UP) - R7-19 (UP) | Always | Below 1 Ω |
R5-8 (DWN) - R7-18 (DOWN) | Always | Below 1 Ω |
R5-7 (OPN) - R7-8 (OPN) | Always | Below 1 Ω |
R5-9 (CLS) - R7-7 (CLS) | Always | Below 1 Ω |
R7-17 (GND9) - Body ground | Always | Below 1 Ω |
R5-2 (E) - Body ground | Always | Below 1 Ω |
R5-10 (UP) or R7-19 (UP) - Body ground | Always | 10 kΩ or higher |
R5-8 (DWN) or R7-18 (DOWN) - Body ground | Always | 10 kΩ or higher |
R5-7 (OPN) or R7-8 (OPN) - Body ground | Always | 10 kΩ or higher |
R5-9 (CLS) or R7-7 (CLS) - Body ground | Always | 10 kΩ or higher |
| REPAIR OR REPLACE HARNESS OR CONNECTOR |
