## DESCRIPTION

This circuit sends signals to the ECM 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 ECM receives the voltage according to the switch condition.

## WIRING DIAGRAM

## INSPECTION PROCEDURE

1.READ DATA LIST (CRUISE CONTROL MAIN SWITCH)

1. Connect the intelligent tester to the DLC3.

1. Turn the ignition switch ON and turn the intelligent tester main switch ON.

1. Check the Data List for proper functioning of the cruise control main switch.

   ECM (Cruise control):
   Item | Measurement Item / Display (Range) | Normal Condition | Diagnostic Note
   Main SW M-CPU | Cruise control main switch signal (Main CPU) / ON or OFF | ON: Cruise control main switch is ON (Main CPU) OFF: Cruise control main switch is OFF (Main CPU) | -
   Main SW M-CPU | Cruise control main switch signal (Main CPU) / ON or OFF | ON: Cruise control main switch is ON (Sub CPU) OFF: Cruise control main switch is OFF (Sub CPU) | -
   Cancel Switch | CANCEL switch signal / ON or OFF | ON: CANCEL switch ON OFF: CANCEL switch OFF | -
   SET/COAST Switch | SET/COAST switch signal / ON or OFF | ON: SET/COAST switch ON OFF: SET/COAST switch OFF | -
   RES/ACC Switch | RES/ACC switch signal / ON or OFF | ON: RES/ACC switch ON OFF: RES/ACC switch OFF | -

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

| OK |

2.INSPECT CRUISE CONTROL MAIN SWITCH

1. Disconnect the cruise control main switch connector.

1. Measure the resistance of the switch.

Standard resistance:

  Tester Connection | Switch Condition | Specified Condition
  3 - 4 | RES/ACC | 216 to 264 Ω
  3 - 4 | SET/COAST | 567 to 693 Ω
  3 - 4 | CANCEL | 1,386 to 1,694 Ω
  3 - 4 | Main switch OFF | 10 kΩ or higher
  3 - 4 | Main switch ON | Below 1 Ω

| NG |

REPLACE CRUISE CONTROL MAIN SWITCH ASSEMBLY

OK |

3.INSPECT SPIRAL CABLE

1. Disconnect the S13 cable connector.

1. Disconnect the cruise control main switch connector.

1. Measure the resistance of the spiral cable.

   Standard resistance:

     Tester Connection | Specified Condition
     A-3 (CCS) - S13-1 (CCS) | Below 1 Ω
     A-4 (ECC) - S13-2 (ECC) | Below 1 Ω

| NG |

REPLACE SPIRAL CABLE SUB-ASSEMBLY

OK |

4.CHECK WIRE HARNESS (SPIRAL CABLE - ECM AND BODY GROUND)

1. Disconnect the S13 cable connector.

1. Disconnect the E13 or E5 ECM connector.

1. Measure the resistance of the wire harness side connectors.

   Standard resistance:
     1GR-FE:

     Tester Connection | Specified Condition
     S13-1 (CCS) - E13-2 (CCS) | Below 1 Ω
     S13-2 (ECC) - Body ground | Below 1 Ω
     S13-1 (CCS) - Body ground | 10 kΩ or higher

     1KD-FTV:

     Tester Connection | Specified Condition
     S13-1 (CCS) - E5-21 (CCS) | Below 1 Ω
     S13-2 (ECC) - Body ground | Below 1 Ω
     S13-1 (CCS) - Body ground | 10 kΩ or higher

| NG |

REPAIR OR REPLACE WIRE HARNESS AND CONNECTOR

OK |
