- 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
PROCEDURE
1. CHECK HARNESS AND CONNECTOR (TC of DLC3 - ECM)
(a) Disconnect the E77 connector of the ECM.
(b) Measure the resistance.
Standard resistance:
(c) Reconnect the ECM connector.
NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR (TC of DLC3 - ECM)
OK -- Continue to next step.
2. CHECK HARNESS AND CONNECTOR (TC of DLC3 - BODY GROUND)
(a) Measure the resistance.
Standard resistance:
NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR (TC CIRCUIT)
OK -- Continue to next step.
3. CHECK HARNESS AND CONNECTOR (CG of DLC3 - BODY GROUND)
(a) Measure the resistance.
Standard resistance:
NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR (CG of DLC3 - BODY GROUND)
OK -- REPLACE ECM
