8 HO TO USE THIS MANUAL The Current Flow Chart section, describes which parts each power source (fuses, fusible links, and circuit breakers) transmits current to. In the Power Source circuit diagram, the conditions when battery power is supplied to each system are explained. Since all System Circuit diagrams start from the power source, the power source system must be fully understood. POE SOUCE (Current Flow Chart) The chart below shows the route by which current flows from the battery to each electrical source (Fusible Link, Circuit reaker, Fuse, etc.) and other parts. The next page and following pages shown the parts to which each electrical source outputs current. POE SOUCE 8 * The system shown here is an EXAMPLE ONLY. It is different to the actual circuit shown in the SYSTEM CICUITS SECTION.

9 The ground points circuit diagram shows the connections from all major parts to the respective ground points. hen troubleshooting a faulty ground point, checking the system circuits which use a common ground may help you identify the problem ground quickly. The relationship between ground points (,, and shown below) can also be checked this way. OUND POINT * The system shown here is an EXAMPLE ONLY. It is different to the actual circuit shown in the SYSTEM CICUITS SECTION. 9

10 TOULESHOOTIN VOLTAE CHECK (a) Establish conditions in which voltage is present at the check point. Example: Ignition S on Ignition S and S on Ignition S, S and elay on (S off) (b) Using a voltmeter, connect the negative lead to a good ground point or negative battery terminal, and the positive lead to the connector or component terminal. This check can be done with a test light instead of a voltmeter. CONTINUITY AND ESISTANCE CHECK (a) (b) Disconnect the battery terminal or wire so there is no voltage between the check points. Contact the two leads of an ohmmeter to each of the check points. If the circuit has diodes, reverse the two leads and check again. hen contacting the negative lead to the diode positive side and the positive lead to the negative side, there should be continuity. hen contacting the two leads in reverse, there should be no continuity. (c) Use the volt/ohmmeter with high impedance (0 kω/v minimum) for troubleshooting of the electrical circuit. 0

11 FINDIN A SHOT CICUIT (a) emove the blown fuse and disconnect all loads of the fuse. (b) Connect a test light in place of the fuse. (c) Establish conditions in which the test light comes on. Example: Ignition S on Ignition S and S on Ignition S, S and elay on (Connect the elay) and S off (or Disconnect S ) (d) Disconnect and reconnect the connectors while watching the test light. The short lies between the connector where the test light stays lit and the connector where the light goes out. (e) Find the exact location of the short by lightly shaking the problem wire along the body. CAUTION: Do not open the cover or the case of the ECU unless absolutely necessary. (If the IC terminals are touched, the IC may be destroyed by static electricity.) DISCONNECTION OF MALE AND FEMALE CONNECTOS To pull apart the connectors, pull on the connector itself, not the wire harness. HINT: Check to see what kind of connector you are disconnecting before pulling apart.

12 TOULESHOOTIN HO TO EPLACEMENT FO TEMINAL (with Terminal etainer Type). DISCONNECT CONNECTO. DISCONNECT TEMINAL FOM CONNECTO (a) for A type aise the terminal retainer up to the temporary lock position. HINT: The needle insertion position varies according to the connector s shape (number of terminals etc.), so check the position before inserting it. for type Open the terminal retainer. (b) elease the locking lug from terminal and pull the terminal out from rear.. INSTALL TEMINAL TO CONNECTO (a) Insert the terminal. HINT:. Make sure the terminal is positioned correctly.. Insert the terminal until the locking lug locks firmly.. Insert the terminal with terminal retainer in the temporary lock position. (b) Push the terminal retainer in as the full lock position.. CONNECT CONNECTO
