Testing the signal at the input of the cruise control unit (Honda CR-V 2)

Components of the optional Inflatable Airbag System (SRS) are located on this site. Before performing any repair or maintenance work, review the location of the SRS components and the precautions to be taken when handling them, as described in the chapter on the SRS system.

1. Disconnect the 14-pin connector from the control unit.

2. Check the connector and contacts to ensure they are making proper contact.

• If contacts are bent, loose, or corroded, correct the problem and retest the system.
• If the contacts are OK, proceed to step. 3.

3. After disconnecting the 14-pin connector, perform a test at the input of the unit.

Contact	Wire	Test condition	Test: required result	Probable cause if result is not achieved
1	Brown with white stripe	Apply power from the battery	Check the operation of the magnetic clutch: The clutch should make a clicking sound and the actuator should be locked.	The drive is faulty Poor grounding(G201) Wire break Short circuit to ground
2	Blue	Turn the ignition key to the ON (II) position, the main switch to the ON position, depress the brake pedal, then release	Check the voltage to ground: When the pedal is pressed, there should be 0 V, and when released, the battery voltage.	The brake pedal position switch is faulty Wire break Open circuit in cruise control main switch Fuse #4 (10A) in under-dash fuse/relay box blown
3	Black	Under all conditions	Check if there is conductivity to ground: There should be conductivity.	Poor grounding (G201) Wire break
4	Green with yellow stripe	Turn the ignition key to the ON (II) position	Check voltage to ground: Should be battery voltage	Fuse #4 (10A) in under-dash fuse/relay box blown Wire break
5	White with black stripe	Press the brake pedal and then release it	Check the voltage to ground: When the pedal is pressed, there should be battery voltage, and when released, 0 V	Fuse #7 (15A) in the under hood fuse/relay box has blown The brake pedal position switch is faulty Wire break
6	Gray with red stripe	Click on the Set button	Check voltage to ground: There should be battery voltage. When testing contact #6, there should be no voltage on contact #7.	Fuse #7 (15A) in the under hood fuse/relay box has blown The horn relay is faulty The SET/RESUME/CANCEL switch is faulty The twisted cable is faulty Wire break
7	Light green with black stripe	Click on the Resume button	Check voltage to ground: There should be battery voltage. When testing contact #7, there should be no voltage on contact #6.
9	Brown	Apply power from the battery to brown contact, and grounding is on brown contact with a yellow stripe	Check the operation of the drive motor: You should hear the noise of the motor	The drive is faulty Wire break
11	Brown with yellow stripe
10	Blue with yellow stripe	Turn the ignition key to the ON (II) position	Short to ground: Cruise control indicator should light up in instrument cluster	Fuse #10 (7.5A) in under-dash fuse/relay box blown The instrument cluster is faulty Wire break
12	Blue with white stripe	Turn the ignition key to the ON (II) position, the main switch to the ON position; lift the front of the car and slowly rotate one wheel while holding the other	Check the voltage between blue contact with a white stripe (+) andblack contact (-): Should be 0-5 V or more multiple times.	The ECM/PCM is faulty Wire break Short circuit to ground
13	Light green	Turn the ignition key to the ON (II) position, the main switch to the ON position	Check voltage to ground: There should be battery voltage.	Fuse #4 (10A) in under-dash fuse/relay box blown The main switch is faulty Wire break
14	White with green stripe (automatic transmission) Blue (manual transmission)	Automatic transmission: Shift the selector lever to position [D] or [D3] Manual transmission: Release the clutch pedal	Check if there is conductivity to ground: There should be conductivity. Note: There should be no conductivity when pressing the clutch pedal or moving the selector lever to other positions.	The gearbox range switch is faulty The clutch pedal position switch is faulty Poor grounding (Manual transmission: G501, Automatic transmission: G101) Wire break
8	Blue with orange stripe	Connect the 14-pin connector to the cruise control unit, turn the main switch to the ON position and drive the vehicle at a speed greater than 40 km/h with the cruise control on.	Check the voltage to ground: There should be a voltage of about 1 V	Loose connection to the PCM block The cruise control unit is faulty Short circuit to ground

4. If any test indicates a problem, identify and correct the cause, then retest. If all tests on the input of the unit pass, the control unit may be faulty. Install a known good control unit and retest. If the system is working properly, replace the control unit.
