9 Functions M162 ENGINE ELECTRICAL 1E Firing order : The ignition cables are located on the cylinder head cover. Each ignition coil provides the high voltage to two spark plugs simultaneously. - T1/1 : cylinder 2 and 5 - T1/2 : cylinder 3 and 4 - T1/3 : cylinder 1 and 6 3. The secondary output voltage (5a) is supplied to the No.2 cylinder spark plug through the spark plug connector. The secondary output voltage (5b) is supplied to the No.5 cylinder spark plug through the ignition cable. The guide pin (W) acts as a ground while the ignition cable is operated. Removal & Installation Procedure 1. Disconnect the negative battery cable (1). 2. Remove the ignition cable connector from the ignition cable. 3. Disconnect the secondary spark plug connectors from the each spark plugs and remove the ignition cable bolt and ignition cable NSm (80-97 lb-in) D Make sure that the ignition cables are correctly routed. D Exactly install the ignition cable guide pin into the vehicle to be grounded. 4. Installation should follow the removal procedure in the reverse order.

10 1E1-10 M162 ENGINE ELECTRICAL Circuit Diagram Inspection & Maintenance Procedure (for MSE) 1. While the ignition switch is in OFF position, remove the wiring connectors (1 and 15) from ignition coil and measure the primary resistance between terminal No.1 and No.15. Specified Value Ω (20 C) Notice: If out of specified value, replace the ignition coil. 2. During engine cranking, measure primary voltage (T1/1) between ECU terminal No. 71 and No. 69. Specified Value V Notice D Measure remaining cables. - T1/2 : No. 72 and T1/3 : No. 70 and 69. D If out of specified value, check ignition cable and ECU. 3. Using a multi -tester, measure the secondary coil resistance between 5a and 5b. Specified Value kω

11 M162 ENGINE ELECTRICAL 1E1-11 UNIT REPAIR BATTERY Inspection Notice D When charging the battery, do not leave the inflammable objects around it. D When checking the electrolyte of battery, put on an eye protector and gloves. 1. Inspect the surface of the battery and replace if any defects were found on it. 2. Check if the specific gravity of the electrolyte is within the specified value. Notice Battery capacity(ah) 90 Battery specific gravity 1.24 Max. tolerance between cells 0.04 D Replace the battery if the maximum tolerance of the electrolyte between cells is out of the specified value. D Measure the specific gravity in the approx. 20 C of ambient temperature. 3. Replenish the electrolyte if necessary.
