Result
Result Proceed to Communication with the vehicle approaching speaker controller is not possible A Communication with the vehicle approaching speaker controller is possible B
B → See step 7
A: Go to next step
- CHECK HARNESS AND CONNECTOR (VEHICLE APPROACHING SPEAKER CONTROLLER - IG1 NO. 1 RELAY AND BODY GROUND)
- Disconnect the L140 vehicle approaching speaker controller connector.
- Measure the voltage according to the value(s) in the table below.
Standard Voltage
Tester Connection Condition Specified Condition L140-1 (IG) - Body ground Power switch on (IG) 11 to 14 V - Measure the resistance according to the value(s) in the table below.
Standard Resistance
Tester Connection Condition Specified Condition L140-7 (GND) - Body ground Always Below 1 Ω
NG → REPAIR OR REPLACE HARNESS OR CONNECTOR
OK: Go to next step
- CHECK HARNESS AND CONNECTOR (VEHICLE APPROACHING SPEAKER CONTROLLER - DLC3)
- Measure the resistance according to the value (s) in the table below.
Standard Resistance
Tester Connection Condition Specified Condition L140-9 (PRST) - L61-7 (SIL) Always Below 1 Ω L140-9 (PRST) or L61-7 (SIL) - Body ground Always 10 kΩ or higher
NG → See step 5
OK: Go to next step
- Measure the resistance according to the value (s) in the table below.
- CHECK HARNESS AND CONNECTOR (DLC3 - BODY GROUND)
- Measure the resistance according to the value (s) in the table below.
Standard Resistance
Tester Connection Condition Specified Condition L61-4 (CG) - Body ground Always Below 1 Ω
NG → REPAIR OR REPLACE HARNESS OR CONNECTOR
OK → See step 8
- Measure the resistance according to the value (s) in the table below.
- CHECK HARNESS AND CONNECTOR (VEHICLE APPROACHING SPEAKER CONTROLLER - INSTRUMENT PANEL JUNCTION BLOCK ASSEMBLY)
- Disconnect the 3A instrument panel junction block assembly connector.
- Measure the resistance according to the value (s) in the table below.
Standard Resistance
Tester Connection Condition Specified Condition L140-9 (PRST) - 3B-11 Always Below 1 Ω L140-9 (PRST) or 3B-11 - Body ground Always 10 kΩ or higher
NG → REPAIR OR REPLACE HARNESS OR CONNECTOR
OK: Go to next step
- CHECK HARNESS AND CONNECTOR (INSTRUMENT PANEL JUNCTION BLOCK ASSEMBLY - DLC3)
- Measure the resistance according to the value (s) in the table below.
Standard Resistance
Tester Connection Condition Specified Condition 3A-48 - L61-7 (SIL) Always Below 1 Ω 3A-48 or L61-7 (SIL) - Body ground Always 10 kΩ or higher
NG → REPAIR OR REPLACE HARNESS OR CONNECTOR
OK → See step 9
- Measure the resistance according to the value (s) in the table below.
- USE SIMULATION METHOD TO CHECK. Refer to HOW TO PROCEED WITH TROUBLESHOOTING [10/2013 - ]
- REPLACE VEHICLE APPROACHING SPEAKER CONTROLLER. Refer to REMOVAL [10/2013 - ]
- REPLACE INSTRUMENT PANEL JUNCTION BLOCK ASSEMBLY. Refer to REMOVAL [10/2013 - ]
