Spark Check for spark at secondary coil wire and each spark plug wire using a spark tester. If spark is not present, continue with following tests. Check spark plug wire resistance on suspect wires. Resistance should be less than 25,000 ohms. Ignition Coil Power Source 1. On Civic, remove distributor cap to check power source directly at coil. On all models, disconnect ignition coil primary leads. Turn ignition on. Using voltmeter, check voltage between ground and Black/Yellow wire terminal of ignition coil harness. 2. Battery voltage should be present. If battery voltage is not present, check for open in Black/Yellow wire between coil and ignition switch. Ignitor Power Source Turn ignition off. Disconnect harness connector at distributor. Turn ignition on. Using voltmeter, check for battery voltage between ground and Black/Yellow wire of harness. If voltage is not present, check for open in Black/Yellow wire between ignition coil and harness connector. If wire is okay, check ignition coil resistance (for internal short to ground). Ignitor Check Check TDC/CRANK/CYL sensor resistance values. See TACH PULSE SIGNAL . Check power sources. If no problems are found and spark is not present, replace ignitor. Ignition Coil Resistance (Accord & Prelude) 1. Remove primary and secondary leads from ignition coil. Using an ohmmeter, check resistance between primary terminals “A” and “C” (“A” and “B” for Prelude) of ignition coil. See Fig. 2 . Resistance should be .6-.8 ohm at room temperature. 2. On Accord, check resistance between terminals “B” and “D” of ignition coil (tachometer circuit). Resistance should be about 2090-2310 ohms at room temperature. 3. On all models, check secondary resistance between terminal “A” and secondary output terminal (coil tower). See IGNITION COIL RESISTANCE table. Check for continuity between terminals “A” and “B” (“A” and “C” for Prelude). Continuity should exist. If readings are not within specification, replace coil.

The vehicle security module monitors the door ajar and remote keyless entry (RKE) status. Based on the door ajar status (doors, liftgate, and liftgate glass), the instrument cluster then energizes the interior lamp relay. When the relay is energized, voltage is supplied to the interior lamp circuits. The interior lamps all receive voltage from the instrument cluster through circuit 53 (BK/LB). Voltage is only provided when the instrument cluster receives a request for interior lamps from either the vehicle security module (when a door, or the liftgate/liftgate glass is opened) or the headlamp switch (when the interior lamp switch is placed in the interior lamps on position). The ajar switches are normally closed (with the doors, or liftgate/liftgate glass closed), and when a door or the liftgate/liftgate glass is opened, the ajar switch is opened alerting the vehicle security module that a door is ajar.
