CHECK HARNESS AND CONNECTOR (RCTA BUZZER - BLIND SPOT MONITOR SENSOR LH) |
(a) Disconnect the R26 RCTA buzzer (blind spot monitor buzzer) connector.
(b) Measure the voltage according to the value(s) in the table below.
Standard Voltage:
|
Tester Connection | Switch Condition |
Specified Condition |
|---|---|---|
|
R26-1 (BZP) - Body ground |
Engine Switch on (IG) |
11 to 14 V |
|
R26-2 (BZN) or W6-3 (BUZ) - Body ground |
Below 1 V | |
|
R26-2 (BZN) - R26-1 (BZP) |
Below 1 V |
| NG | | REPAIR OR REPLACE HARNESS OR CONNECTOR |

CHECK HARNESS AND CONNECTOR (RCTA BUZZER - BLIND SPOT MONITOR SENSOR LH AND BATTERY) |
(a) Disconnect the R26 RCTA buzzer (blind spot monitor buzzer) connector.
(b) Disconnect the W6 blind spot monitor sensor LH connector.
(c) Measure the resistance according to the value(s) in the table below.
Standard Resistance:
|
Tester Connection | Condition |
Specified Condition |
|---|---|---|
|
R26-2 (BZN) - W6-3 (BUZ) |
Always | Below 1 Ω |
|
R26-2 (BZN) or W6-3 (BUZ) - Body ground |
Always | 10 kΩ or higher |
(d) Measure the voltage according to the value(s) in the table below.
Standard Voltage:
|
Tester Connection | Switch Condition |
Specified Condition |
|---|---|---|
|
R26-2 (BZN) or W6-3 (BUZ) - Body ground |
Engine switch on (IG) |
Below 1 V |
|
R26-1 (BZP) - Body ground |
Engine switch on (IG) |
11 to 14 V |
|
R26-1 (BZP) - Body ground |
Engine switch off | Below 1 V |
| OK | | REPLACE BLIND SPOT MONITOR BUZZER
|
| NG | | REPAIR OR REPLACE HARNESS OR CONNECTOR |
