Master cylinder warning: when battery is disconnected, vehicle computer and memory systems may lose memory data. Driveability problems may exist until computer systems have completed a relearn cycle. See computer relearn procedures article in general information before disconnecting battery. Removal & Installation 1. Disconnect battery ground cable. 2. Loosen air cleaner outlet tube clamps. Disconnect hose to outlet tube. Remove the air cleaner outlet tube. See fig. 27 and fig. 28 note: . Disconnect the maf harness connector. Fig. 29 unclip the accelerator cable. See fig. 30 . Separate the air cleaner from the battery tray. See fig. 31 . Remove the air cleaner. Disconnect the speed control switch harness connector. See fig. 32 . Disconnect the fluid level sensor harness connector. See fig. 33 . Disconnect the brake tubes. Remove the wiring bracket nut. See fig. 34 . Position the wiring bracket aside. Remove the brake master cylinder nuts. Remove the brake master cylinder. To install, reverse removal procedure. Bleed brakes. See bleeding brake system .

Accord 1. Disable air bag system. See air bag restraint systems article. Turn ignition off. Remove instrument panel lower left cover. Remove left knee bolster. Remove underdash fuse/relay box, located near left kick panel. 2. Remove driver’s multiplex control unit from underdash fuse/relay box. Ensure connector and socket terminals are okay. Repair as necessary and retest system. If connector and terminals are okay, use a dvom to perform control unit input test. See fig. 9 . If an input test indicates a problem, find and correct cause and retest system. If all input test results are okay, replace faulty multiplex control unit.Removal & installation disable air bag system. See air bag restraint systems article. Disconnect negative battery cable. Remove dash lower trim cover and knee bolster. Remove steering column covers. Disconnect wiper/washer switch connectors. Remove 2 screws and wiper/washer switch. To install, reverse removal procedure.

1996-2000 electrical fuses & circuit breakers – civic identification caution: when battery is disconnected, vehicle computer and memory systems may lose memory data. Driveability problems may exist until computer systems have completed a relearn cycle. See computer relearn procedures article in general information before disconnecting battery. Under-dash fuse/relay box note: under-dash fuse/relay box is located under driver’s side of instrument panel. See fig. 1 or fig. 2 .

Removal & installation warning: vehicles are equipped with air bag supplemental restraint system. Before attempting any repairs involving steering column, instrument panel or related components, see service precautions (or air bag safety precautions) and disabling & activating air bag system in appropriate air bag restraint systems article. Battery disconnect precautions air bag warning: no one must be in vehicle when battery is connected. This is a safety precaution in case an air bag module activates when power is connected. Ecm if connector is disconnected from ecm or battery is disconnected, all adaptation values in control module are erased. To achieve optimal anti-theft protection for vehicle, an anti-theft immobilizer was installed. Anti-theft immobilizer is a system for enabling/locking engine control module (ecm) through the w-wire. This system cannot be circumvented, it is necessary to perform adaptation of anti-theft immobilizer using vas 5052 in on board diagnostic function. The great availability of equipment options makes adaptation of ecm necessary (e.G. Cruise control system). This “writing” function is not possible with a generic scan tool, therefore it is necessary to use vas 5052 in on board diagnostic function for this purpose. Dtc memory content will remain intact however. If engine is started after this, a rough, uneven idle can result. In this case, ecm readiness code must be regenerated.

Emission systems & sub-systems exhaust gas recirculation (egr) system test note: note: egr systems contain different components depending on application. See fig. 19 . When testing egr system and components, use proper illustration to determine component location. When performing egr system test, it may be necessary to monitor engine rpm by using scan tool. For scan tool connections, see idle speed & mixture in adjustments article. 1. Ensure egr vacuum modulator filter is clean and in good condition. Clean filter with compressed air (if necessary). Note: egr vacuum modulator filter must be installed with coarse side facing upward, away from egr vacuum modulator. 2. Using “t” connector, install vacuum gauge in line with vacuum hose on top of egr valve. Start engine. Ensure engine idles smoothly to ensure proper seating of egr valve. 3. Install jumper wire (sst 09843-18020) between terminals te1 and e1 on data link connector no. 1 located in engine compartment. See fig. 15 . Note: the egr system components must be checked with engine coolant temperature less than minimum temperature and engine at specified engine rpm. 4. Operate engine with engine coolant temperature less than minimum temperature and at specified engine rpm. See egr testing specifications table. No vacuum reading should be obtained. 5. Warm engine to more than the specified operating temperature. See egr testing specifications table. Operate engine at specified engine rpm again. See egr testing specifications table. Ensure a low vacuum reading is obtained with engine at the specified rpm. 6. Disconnect vacuum hose from port “r” on egr vacuum modulator. See fig. 18 . Using additional hose, connect port “r” on egr vacuum modulator directly to intake manifold. High vacuum reading should be obtained at specified engine rpm. See egr testing specifications table.
