Cruise Control Switch Circuit

CRUISE CONTROL: CRUISE CONTROL SYSTEM: Cruise Control Switch Circuit
- Cruise Control Switch Circuit

DESCRIPTION

This circuit sends a signal to the hybrid vehicle control ECU depending on the cruise control switch condition. The battery supplies positive (+) battery voltage to the circuit control switch. Then terminal CCS of the hybrid vehicle control ECU receives the voltage according to the switch condition.

INSPECTION PROCEDURE

PROCEDURE

1. READ VALUE USING TECHSTREAM (CRUISE CONTROL SWITCH)

(a) Check the Data List for proper functioning of the cruise control switch Cruise Control System.

Cruise Control





OK:

When cruise control switch operation is performed, the results are the same as above.

NG -- INSPECT CRUISE CONTROL SWITCH

OK -- PROCEED TO NEXT CIRCUIT INSPECTION SHOWN IN PROBLEM SYMPTOMS TABLE Cruise Control System

2. INSPECT CRUISE CONTROL SWITCH

(a) Remove the cruise control switch Removal.





(b) Measure the resistance according to the value(s) in the table below.

Standard resistance:





NG -- REPLACE CRUISE CONTROL SWITCH Removal
OK -- Continue to next step.

3. INSPECT SPIRAL CABLE SUB-ASSEMBLY





(a) Disconnect the z2 wire connector.

(b) Disconnect the L126 cable connector.

(c) Measure the resistance according to the value(s) in the table below.

Standard resistance:





NG -- REPLACE SPIRAL CABLE SUB-ASSEMBLY Removal
OK -- Continue to next step.

4. INSPECT CRUISE CONTROL SWITCH WIRE

(a) Disconnect the z2 cable connector.





(b) Disconnect the A switch connector.

(c) Measure the resistance according to the value(s) in the table below.

Standard resistance:





NG -- REPLACE CRUISE CONTROL SWITCH WIRE
OK -- Continue to next step.

5. CHECK HARNESS AND CONNECTOR (SPIRAL CABLE - HYBRID VEHICLE CONTROL ECU AND BODY GROUND)





(a) Disconnect the L126 cable connector.

(b) Disconnect the A74 ECU connector.

(c) Measure the resistance according to the value(s) in the table below.

Standard resistance:





NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR

OK -- REPLACE HYBRID VEHICLE CONTROL ECU Removal
