DESCRIPTION
DTC output mode is set by connecting terminals TC and CG of the DLC3.DTCs are indicated by the blinking pattern of the ABS warning light.
WIRING DIAGRAM
- HINT:
- When warning lights continue to blink, a ground short in the wiring of terminal TC of the DLC3 or an internal ground short in one or more ECUs is suspected.
INSPECTION PROCEDURE
- HINT:
- Check the condition of each related circuit connector before troubleshooting (Click here).

2.CHECK HARNESS AND CONNECTOR (ECM TO DLC3) |
Disconnect the ECM connector.
Measure the resistance according to the value(s) in the table below.
- Standard resistance:
Tester Connection Specified Condition A24-27 (TC) - E10-13 (TC) Below 1 Ω E10-13 (TC) - Body ground 10 kΩ or higher
Connect the connector.

OK | |
3.CHECK HARNESS AND CONNECTOR (DLC3 CG CIRCUIT) |
Measure the resistance according to the value(s) in the table below.
- Standard resistance:
Tester Connection Specified Condition E10-4 (CG) - Body ground Below 1 Ω
|
| ||||
OK | |
4.REPAIR OR REPLACE HARNESS OR CONNECTOR (TC TERMINAL CIRCUIT) |
Measure the resistance according to the value(s) in the table below.
- Standard resistance:
Tester Connection Specified Condition E10-13 (TC) - Body ground 10 kΩ or higher
