The system also incorporates spark plugs, HT leads, an ignition HT coil and associated wiring. The system is divided into two circuits, which are the primary (low tension/LT) and secondary (high tension/HT) circuits. The primary circuit consists of the battery, ignition switch, ignition HT coil primary windings, ECU and wiring. The secondary circuit consists of the ignition HT coil secondary windings, the distributor cap and rotor arm, the spark plugs and the interconnecting HT leads. The ECU controls both the ignition system and the fuel injection system, integrating the two in a complete engine management system. Refer to Chapter 4 for information on any part of the system not given in this Chapter. As far as the ignition system is concerned, the ECU receives information in the form of electrical impulses or signals from the crankshaft sensor (which gives it the engine speed and crankshaft position), from the coolant temperature sensor (which gives it the engine temperature), from the throttle pedal switch (which tells it when the throttle is closed) and from the manifold absolute pressure sensor (which gives it the load on the engine). All these signals are compared by the ECU, using digital techniques, with set values pre-programmed (mapped) into its memory. Based on this information, the ECU selects the ignition timing appropriate to those values and controls the ignition HT coil accordingly. This means that the distributor is just that, a distributor of the HT pulse to the appropriate spark plug. It has no effect whatsoever on the ignition timing. Also, the system is so sensitive that, at idle speed, the ignition timing may be constantly changing. This should be remembered if trying to check the ignition timing. Precautions Refer to Part A of this Chapter. 2 Spark plugs - renewal Refer to Chapter 1. 3 HT leads, distributor cap and rotor arm - inspection and renewal 1 Refer to Chapter 1. Note the anti-flash shield fitted beneath the rotor arm. 4 HT coil - removal, testing and refitting 1 Refer to Section 4 in Part A of this Chapter. 1689 Rover 214 & 414 Updated Version 09/97 5 Distributor - removal and refitting 3 Removal 1 Disconnect the battery negative terminal. 2 Disconnect the HT leads from the spark plugs. 3 Undo the two distributor cap retaining screws and remove the cap and leads as an assembly. 4 Slacken and remove the grub screw securing the rotor arm to the camshaft end then pull off the rotor arm (see illustration). 5 Remove the distributor cap insulating plate from the cylinder head. 6 Examine each components for signs of wear or damage and renew as necessary. Refitting 7 Refitting is a reverse of the removal procedure. Tighten the rotor arm grub screw and distributor cap screws to the specified torque settings. 5.4 Distributor assembly 1 Distributor cap 3 Grub screw 2 Rotor arm 4 Insulating plate
