INSPECTION PROCEDURE
CHECK WIRE HARNESS (TERMINAL TC of DLC3 - ECM)
CHECK WIRE HARNESS (TERMINAL CG of DLC3 - BODY GROUND)
CHECK WIRE HARNESS (TERMINALTC of DLC3 - BODY GROUND)
DYNAMIC RADAR CRUISE CONTROL SYSTEM - TC and CG Terminal Circuit
DESCRIPTION
Connecting terminals TC and CG of the DLC3 causes the system to enter the self-diagnostic mode. If a malfunction is present, DTCs will be output.
- When a particular warning light remains blinking, a ground short in the wiring of terminal TC of the DLC3 or an internal ground short in the relevant ECU is suspected.
WIRING DIAGRAM
INSPECTION PROCEDURE
| 1.CHECK WIRE HARNESS (TERMINAL TC of DLC3 - ECM) |
Disconnect the A6 connector from the ECM.
Measure the resistance according to the value(s) in the table below.
- Standard resistance:
| Tester Connection | Condition | Specified Condition |
| A6-3 (TC) - J21-13 (TC) | Always | Below 1 Ω |
| | REPAIR OR REPLACE HARNESS OR CONNECTOR (DLC3 - ECM) |
|
|
| 2.CHECK WIRE HARNESS (TERMINAL CG of DLC3 - BODY GROUND) |
Measure the resistance according to the value(s) in the table below.
- Standard resistance:
| Tester Connection | Condition | Specified Condition |
| J21-4 (CG) - Body ground | Always | Below 1 Ω |
| | REPAIR OR REPLACE HARNESS OR CONNECTOR (DLC3 - BODY GROUND) |
|
|
| 3.CHECK WIRE HARNESS (TERMINALTC of DLC3 - BODY GROUND) |
Measure the resistance according to the value(s) in the table below.
- Standard resistance:
| Tester Connection | Condition | Specified Condition |
| J21-13 (TC) - Body ground | Always | 10 kΩ or higher |
| | REPAIR OR REPLACE HARNESS OR CONNECTOR OR EACH ECU |
|
|
| OK | |
