TC and CG Terminal Circuit

CRUISE CONTROL: CRUISE CONTROL SYSTEM: TC and CG Terminal Circuit
- 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
