Ture HONDA CR-V 1999 RD1-RD3 / 1.G Workshop Manual

Anti-lock Brake System (ABS)
Features/Gonstruction (cont'd)
ABS Modulator
The ABS modulator consists of the inlet solenoid valve, outlet solenoid valve, reservoir, pump, pump motor and thedampjng chamber.
The modulator reduces the caliper fluid pressure directly. lt is a circulating-type modulator because the brake fluid circulatesthrough the caliper, reservoir and the master cylinder.The hydraulic control has three modes: pressure reduction, pressure retaining and pressure intensifying modes.The hydraulic circuit is the independent four channel-type, one channel for each wheel.
SOLENOID VALVE
t-
Pressure intensifying mode: Inlet valve open, outlet valve closed,
Pressure retaining mode:
Pressure reduction mode:
Motor operation mode:
Master cylinder fluid is pumped out to the caliper.Inlet valve closed, outlet valve closed.
Caliper fluid is retained by the inlet valve and outlet valve.Inlet valve closed, outlet valve ooen
Caliper fluid flows through the outlet valve to the reservoir.When starting the pressure reduction mode. the pump motor is ON.When stopping ABS operation, the pump motor is OFF.The reservoir fluid is pumped out by the pump, through the damping chamber, to the mastercylinder.

Moldings
Door Moldings Replacement (cont'd)
It the old molding is to be reinstalled:
The following materials and tools are required to repair
the molding.
NOTE: Followthe manufacturer's instructions.
Materials: (Reference)
. Stripe remover
3M 08907
. Stripe adhesive remover
3M 08908
. Adhesive tape
3M Super Automotive Attachment Tape
Tools:
. Protective tape
. Knife or Cutter
. Sponge or Shop towel
. Infrared dryer
. Film
. Plastic putty knife
. Alcohol
CAUTION: Put on gloves to protect your hands,
1. lf necessary, replace any damaged clips on the mold-
ang.
2. Apply the stripe remover evenly to the bonding sur-
face of the body and molding.
3. Cover the bonding surface of the body and molding
with a film, then heat to 104 - 122"F (40 - 50'C) for 5- 10 minutes with an infrared dryer.
NOTE: Use care when heating to prevent deforma-
tion of the body and molding.
4. Carefully scrape the adhesive tape with a plastic
putty knife.
For removal of adhesive tape residue, follow-up with
stripe adhesive remover, then scrape the adhesive
tape with a plastic putty knife.
Remove the protective tape, then clean the bonding
surface with a sponge dampened in alcohol.
NOTE: Make sure the bonding surface is kept free or
water, oil and grease.
7. Glue the new adhesive tape

This vehicle uses HFC-I34a (R-l34a) refrigerant which does not contain chlorofluorocarbons. Pay attention to the follow-ing service items:
. Do not mix refrigerants CFC-12 (R-12) and HFC-l34a (R-134a). They are not compatible.. Use only the recommended polyalkyleneglycol (PAG) refrigerant oil (SP-10) designed for the R-134a compressor.Intermixing the recommended (PAG) refrigerant oil with any other refrigerant oil will result in compressor failure.. Afl Ay'C system parts (compressor, discharge line. suction line, evaporator, condenser. receiver/dryer, expansion valve,O-rings for joints) have to be proper for refrigerant R-134a. Do not confuse with R-12 parts.
. Use a halogen gas leak detector designed for refrigerant R-134a.. R-12 and R-134a refrigerant servicing equipment are not interchangeable. Use only a recovery/recycling/charging stationthat is U.L.iisted and is certified to meet the requirements of SAE J2210 to service R-134a air conditioning system.. Always recover the refrigerant R-134a with an approved recovery/recycling/charging station before disconnecting anylVC fitting.

Self-diagnosis Function
The heater control panel has a self-diagnosis function.
Running the Self-diagnosis Function'97 mod€l:
Turn the ignition switch ON {ll), then set the mode control dial to the Vent position, and the recirculation controt switch toRecirculate {recirculation indicator light comes on). Press and hold the recirculation control switch to Fresh (recirculation indi-cator light goes off). Continue to hold the switch; the recirculation indicator light will come on for two seconds. then it willblink the Diagnostic Trouble Code (DTC) to indicate a iaulty component. lf no DTC'S are found, the indicator liqht will notblink atter the initial two second light.
'98 - 00 models:
Set the mode control dial to the Vent position, and turn the ignition switch ON (ll). Within six seconds after turning the igni-tion switch on, press the recirculation control switch the required number of times depending on the recirculation indicatorlight status:
.lftheindicatorlightisON,presstherecirculationcontrol switch five times..lftheindicatorlightisOFF,presstherecirculationcontrol switch six I|mes.The recirculation indicator light will come on for two seconds, then blink the Diagnostic Trouble Code (DTC) to indicate afaulty component. lf no DTC'S are found, the indicator light will not blink after the initial two second liqht.

Troubleshooting
Air Mix Control Motor
Recirculation indicator light indicates Diagnostic Trouble Code (DTC) 1: A problem in the air mix control motor circuit.
The air mix control motor regulates the mixture of cool/hot air according to outputs from the heater control panel.
Selt-diagnosis circuit check indi-cates a Droblem in the air mixcontrol motor circuil.
Chock the air mix control moior:1. Disconnect the air mix controlmotor 5P connector,2, Test the air mix control motor(see page 22-43).
Check the air mix control linkagoand doors:1. Remove the air mix controlmotor (see page 22'43).2. Check the air mix control linkage and doors for smooth

Troubleshooting
Evaporator Temperature Sensor
Recirculation indicator light indicates Diagnostic Trouble code (OTC) 3: A problem in the evaporator temperature sensor circuit.
The evaporator temperature sensor is a temperature dependent resistor {thermistor}. The resistance of the thermistordecreases as the evaporator outlet air temperature increases.
