Subject: Defective Lighting
My automobile is an 1997 Honda Accord LX, with 87,000 Km. on the odometer. Recently I have
experienced an annoying intermittent lighting problem. When the car is first started, I have an
illuminated daytime running light (DRL) indicator lamp,and a dimly lit high beam indicator lamp.
When the parking brake is released these lamps are extinguished. According to the manual, this
is normal. Lately, however, upon release of the parking brake these lamps extinguish for about
one second and then light again. coincident with this, is a failure to light the right high beam. I
recently lifted the hood to examine the wiring insulation and connections at the lamp assemblies
during a failure. manipulation of the wiring at the lamp sockets had no effect on the failure. When
I dropped the hood to close up, the condition cleared. The dealer had a look at it and changed the
high beam lamp in question. They feel it is the Daytime running light control unit. The accord
manual I have has some pretty good circuit diagrams of the lighting system, but in the entire book
I can find no mention of the location of the control unit. I would like to check this a little further.
Can you tell me where to find this unit, and can you tell me if it's possible to find some detailed
data on the control unit. Thank you. My name and address are as follows.
Module Madness
You have entered the module zone, where many technicians get challenged! I believe you have
already had the correct diagnosis of a malfunctioning (DRL) Daytime Running Light module
(these are common to fail or malfunction), what you want to know is how can you find where it is
located and whether or not you can possibly repair it.
The location of the module is to the left side of the dash near the centre console (very close to the
gas pedal area), there is a cluster of 3 components: Shifter Interlock module, PGM-FI Main Relay
and Daytime Running Light module (if you have a manual transmission then there will also be a
starter cut relay as well), the DRL should have a 14 pin connector.
There is not any published information for repair of the module, once the diagnosis of a failed
module the factory procedure is to replace the module, if you have a background in electronics it
is possible to repair it using components from a place like Radio Shack, I will attach a copy of the
circuit wiring diagram and you can make the decision as to whether repairing or replacement
