Cruise Control Switch Circuit

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

DESCRIPTION

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

OK:

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

NG -- INSPECT CRUISE CONTROL MAIN SWITCH

OK -- PROCEED TO NEXT SUSPECTED AREA SHOWN IN PROBLEM SYMPTOMS TABLE Cruise Control System

2. INSPECT CRUISE CONTROL MAIN SWITCH





Text in Illustration





(a) Disconnect the cruise control main switch connector.

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

Standard Resistance:





*1: Lever is in the neutral position

(c) Reconnect the cruise control main switch connector.

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

3. CHECK HARNESS AND CONNECTOR (CRUISE CONTROL MAIN SWITCH - SPIRAL CABLE SUB-ASSEMBLY)

(a) Disconnect the spiral cable connector.

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

Standard resistance





(c) Reconnect the spiral cable connector.

NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR (CRUISE CONTROL MAIN SWITCH - SPIRAL CABLE SUB-ASSEMBLY)
OK -- Continue to next step.

4. INSPECT SPIRAL CABLE SUB-ASSEMBLY





(a) Disconnect the spiral cable connector.

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

Standard resistance

(c) Reconnect the spiral cable connector.

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

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

(a) Disconnect the spiral cable connector.

(b) Disconnect the hybrid vehicle control ECU connector.

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

Standard resistance:





(d) Reconnect the spiral cable connector.

(e) Reconnect the hybrid vehicle control ECU.

NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
