CRUISE CONTROL SYSTEM (for Sedan) - TC and CG Terminal Circuit |
DESCRIPTION
The DLC3 circuit enables reading of Diagnostic Trouble Codes (DTCs) without using Techstream by connecting terminals TC and CG of the DLC3 connector.Stored DTCs are displayed in blinking patterns of the CRUISE MAIN indicator light located on the combination meter.
WIRING DIAGRAM
- HINT:
- When a particular warning light blinks continuously, a ground short in the wiring of terminal TC of the DLC3 or an internal ground short in the relevant ECU is suspected.
INSPECTION PROCEDURE
| 1.CHECK HARNESS AND CONNECTOR (TC of DLC3 - ECM) |
Disconnect the A21 connector of the ECM.
Measure the resistance.
- Standard resistance:
Tester Connection
| Specified Condition
|
TC (D15-13) - TC (A21-27)
| Below 1 Ω
|
Reconnect the ECM connector.
| | REPAIR OR REPLACE HARNESS OR CONNECTOR (TC of DLC3 - ECM) |
|
|
| 2.CHECK HARNESS AND CONNECTOR (TC of DLC3 - BODY GROUND) |
Measure the resistance.
- Standard resistance:
Tester Connection
| Specified Condition
|
TC (D15-13) - Body ground
| 10 kΩ or higher
|
| | REPAIR OR REPLACE HARNESS OR CONNECTOR (TC CIRCUIT) |
|
|
| 3.CHECK HARNESS AND CONNECTOR (CG of DLC3 - BODY GROUND) |
Measure the resistance.
- Standard resistance:
Tester Connection
| Specified Condition
|
CG (D15-4) - Body ground
| Below 1 Ω
|
| | REPAIR OR REPLACE HARNESS OR CONNECTOR (CG of DLC3 - BODY GROUND) |
