'03-05 Models

WARNING: This page is about a different car, the 2007 Honda Accord, 2006 Honda Accord, 2005 Honda Accord, 2004 Honda Accord, and 2003 Honda Accord. However, it is still accessible from the selected car via links, so may be relevant.

There are SRS components are located in this area. Review the SRS component locations (see COMPONENT LOCATION INDEX ) and precautions and procedures (see PRECAUTIONS AND PROCEDURES ), before doing repairs or service.

Disconnect the 14P connector from the control unit.
Inspect the connector and socket terminals to make sure they are all making good contact.
- If the terminals are bent, loose, or corroded, repair them as necessary, and recheck the system.
- If the terminals look OK, go to step 3.

With the 14P connector disconnected, do these input tests.
- If test indicates a problem, find and correct the cause, then recheck the system.
- If all the input tests prove OK, the cruise control unit may by faulty. Substitute a known-good cruise control unit, and retest. If the system works properly, replace the cruise control unit.

CRUISE CONTROL UNIT INPUT TEST (2003-05 MODELS)

Cavity	Wire	Test condition	Test: Desired result	Possible cause if result is not obtained
1	BRN/BLK	Connect battery power	Check the operation of the magnetic clutch: Clutch should click and output link should be locked.	Faulty brake pedal position switch Faulty actuator Poor ground (G202) An open in the wire Short to ground
3	BLK	Under all conditions	Check for continuity to ground: There should be continuity.	Poor ground (G501) An open in the wire
4	BLK/RED	Ignition switch ON (II)	Check for voltage to ground: There should be battery voltage.	Blown No. 18 (15A) fuse in the under-dash fuse/relay box An open in the wire
5	WHT/BLK	Brake pedal pressed, then released	Check for voltage to ground: There should be battery voltage with the pedal pressed, and 0 V with the pedal released.	Blown No. 13 (20A) fuse in the under-hood fuse/relay box Faulty brake pedal position switch An open in the wire
6	GRY/RED	Set/decel switch pressed	Check for voltage to ground: There should be battery voltage. When testing terminal No. 6, there should be no voltage on terminal No. 7.	Blown No. 13 (20A) fuse in the under-hood fuse/relay box Faulty horn relay Faulty cruise control combination switch Faulty cable reel An open in the wire
7	LT GRN/BLK	Resume/accel switch pressed	Check for voltage to ground: There should be battery voltage. When testing terminal No. 7, there should be no voltage on terminal No. 6.
9	BRN/YEL	Connect battery power to the BRN/YEL terminal and ground to the BRN/WHT terminal	Check the operation of the actuator motor: You should hear the motor.	Faulty actuator An open in the wire
11	BRN/WHT			Faulty actuator An open in the wire
10	BLU/YEL	Ignition switch ON (II)	Attach to ground: CRUISE CONTROL indicator in the gauge assembly should comes on.	Blown bulb Faulty gauge control module An open in the wire
12	BLU/WHT	Ignition switch ON (II) and cruise control main switch ON; raise the front of the vehicle, and rotate one wheel slowly while holding the other wheel NOTE: This input test must be done with the 14P connector reconnected.	Check for voltage between the BLU/WHT (+) and BLK (-) terminal: There should be 0---5 V or more repeatedly.	Faulty ECM/PCM An open in the wire Short to ground
13	LT GRN	Cruise control main switch ON, then OFF	Check for continuity between No. 2 terminal and No. 13 terminal: There should be continuity with the cruise control main switch ON and no continuity with the cruise control main switch OFF.	Faulty cruise control combination switch Faulty cable reel An open in the wire
14	M/T: LT BLU	Clutch pedal released	Check for continuity to ground: There should be continuity. NOTE: There should be no continuity when the clutch pedal is pressed.	Faulty clutch pedal position switch Poor ground (G501) An open in the wire
14	A/T: PNK	Shift lever in D, D3	Check for continuity to ground: There should be continuity. NOTE: There should be no continuity when shift lever is in other positions.	Faulty ECM/PCM An open in the wire
2	PNK	Reconnect the cruise control unit 14P connector, turn the ignition switch ON (II), and cruise control main switch ON	Check for voltage to ground: There should be battery voltage.	Blown No. 18 (15A) fuse in the under-dash fuse/relay box Faulty cruise control unit Short to ground
8	BLU/BLK	Reconnect the cruise control unit 14P connector, start the engine, press the cruise control main switch ON, and drive the vehicle at speeds over 25 mph (40 km/h) with the cruise control set	Check for voltage to ground: There should be about 1V	Blown No. 18 (15A) fuse in the under-hood fuse/relay box Faulty cruise control unit Short to ground Cruise control communication circuit problem (see CRUISE CONTROL COMMUNICATION CIRCUIT TROUBLESHOOTING )
