INSPECTION PROCEDURE
CHECK WIRE HARNESS (TERMINAL TC of DLC3 - ECM)
CHECK WIRE HARNESS (TERMINAL CG of DLC3 - BODY GROUND)
CHECK WIRE HARNESS (TERMINAL TC of DLC3 - BODY GROUND)
CRUISE CONTROL SYSTEM - TC and CG Terminal Circuit |
DESCRIPTION
Connecting terminals TC and CG of the DLC3 causes the system to enter self-diagnostic mode. If a malfunction is present, DTCs will be output.- HINT:
- 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 A55 connector from the ECM. (2GR-FE (LHD))
Disconnect the A24 connector from the ECM. (2AZ-FE, 2GR-FE (RHD))
Measure the resistance according to the value(s) in the table below.
- Standard resistance:
Tester Connection
| Condition
| Specified Condition
|
A55-27 (TC) - E10-13 (TC)*1
A24-27 (TC) - E10-13 (TC)*2
| Always
| Below 1 Ω
|
- HINT:
- *1:2GR-FE (LHD)
- *2:2AZ-FE, 2GR-FE (RHD)
| | 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
|
E10-4 (CG) - Body ground
| Always
| Below 1 Ω
|
| | REPAIR OR REPLACE HARNESS OR CONNECTOR (DLC3 - BODY GROUND) |
|
|
| 3.CHECK WIRE HARNESS (TERMINAL TC of DLC3 - BODY GROUND) |
Measure the resistance according to the value(s) in the table below.
- Standard resistance:
Tester Connection
| Condition
| Specified Condition
|
E10-13 (TC) - Body ground
| Always
| 10 kΩ or higher
|
| | REPAIR OR REPLACE HARNESS OR CONNECTOR OR EACH ECU |
