Cancel Code 11

Circuit description

In addition to switching the cruise control system to ON/OFF, the cruise control main switch can operate the following seven functions. For SET, -(COAST), TAP DOWN, use -SET switch. For RES, +(ACCEL), TAP UP, use +RES switch. For CANCEL, use CANCEL switch. As the cruise control main switch is an auto return type switch, it is ON while operated in each arrowed direction, and OFF while not operated. Inner contact of the cruise control main switch turns to ON by operating the switch. ECM identifies voltages for each switch operation.

Inspection steps

1. Check cruise control main switch circuit.
   1. Remove the driver's airbag module.
   2. Disconnect the cruise control command switch connector.
   3. Turn the ignition switch to ON.
   4. Measure the voltage between connector terminal and chassis ground.
   VOLTAGE SPECIFICATION
   
   

   Inspection terminals	Inspection conditions	Standard value
   Z8-11 - chassis ground	IG ON	5V or more

   NG: Check the roll connector, and repair or replace the harness.

   OK: Go to Next Step

2. Check cruise control main switch circuit.
   1. Turn the ignition switch to OFF.
   2. Measure the resistance between connector terminal and chassis ground.
   RESISTANCE SPECIFICATION (OPEN CIRCUIT CHECK)
   
   

   Inspection terminals	Inspection conditions	Standard value
   Z8-10 - chassis ground	Always	Less than 10 Ω

   NG: Check ECM and roll connector, and repair or replace the harness.

   OK: Go to Next Step

3. Check cruise control main switch circuit.
   1. Measure the resistance when the cruise control main switch is not in operation.
   RESISTANCE SPECIFICATION (OPEN CIRCUIT CHECK)
   
   

   Inspection terminals	Inspection conditions	Standard value
   Cruise control main switch side connector terminal 10 - cruise control main switch side connector terminal 11	IG ON	1 MΩ or more

   NG: Replace the cruise control main switch.

   OK: Go to Next Step

4. Check cruise control main switch circuit.
   1. Measure the resistance when the cruise control ON-OFF switch is pressed.
   RESISTANCE SPECIFICATION (OPEN CIRCUIT CHECK)
   
   

   Inspection terminals	Inspection conditions	Standard value
   Cruise control main switch side connector terminal 10 - cruise control main switch side connector terminal 11	IG ON	Less than 1 Ω

   NG: Replace the cruise control main switch.

   OK: Go to Next Step

5. Check cruise control main switch circuit.
   1. Measure the resistance when the CANCEL switch is pressed.
   RESISTANCE SPECIFICATION (OPEN CIRCUIT CHECK)
   
   

   Inspection terminals	Inspection conditions	Standard value
   Cruise control main switch side connector terminal 10 - cruise control main switch side connector terminal 11	Always	Approx. 630 Ω

   NG: Replace the cruise control main switch.

   OK: Go to Next Step

6. Check cruise control main switch circuit.
   1. Measure the resistance when the -SET switch is pressed.

   Resistance (open circuit check)

   Inspection terminals	Inspection conditions	Standard value
   Cruise control main switch side connector terminal 10 - cruise control main switch side connector terminal 11	Always	Approx. 1540 Ω

   NG: Replace the cruise control main switch.

   OK: Go to Next Step

7. Check cruise control main switch circuit.
   1. Measure the resistance when the +RES switch is pressed.
   RESISTANCE SPECIFICATION (OPEN CIRCUIT CHECK)
   
   

   Inspection terminals	Inspection conditions	Standard value
   Cruise control main switch side connector terminal 10 - cruise control main switch side connector terminal 11	Always	Approx. 240 Ω

   NG: Replace the cruise control main switch.

   OK: Replace the ECM.
