  1. Disconnect the negative battery cable.
  2. Remove in the order indicated in the table.
  3. Install in the reverse order of removal.

PCM REPLACEMENT [L3]

  1. Connect the WDS or equivalent to the DLC-2.
  2. Set up the WDS or equivalent (including the vehicle recognition).
  3. Select "Module Programming".
  4. Select "Programmable Module Installation".
  5. Select "PCM" and perform procedures according to directions on the WDS or equivalent screen. NOTE: If the PCM is replaced with a new one, the PCM stores DTC P0602 and illuminates the MIL even though no malfunction is detected. When the configuration is completed, DTC P0602 is cleared.
  6. Retrieve DTC's by the WDS or equivalent, then verify that there in no DTC present. If DTC is present, perform applicable DTC inspection. (See «DTC TABLE [L3]»(ref-244554-S15056466722006092500000) ).

ENGINE COOLANT TEMPERATURE (ECT) SENSOR REMOVAL/INSTALLATION [L3]

  1. Drain the engine coolant. (See «COOLING SYSTEM SERVICE WARNINGS [L3, AJ]»(ref-244562-S18278447982006092500000) ).
  2. Disconnect the ECT sensor connector.
  3. Remove the ECT sensor.
  4. Install in the reverse order of removal. Tightening torque 10-14 N.m {1.02-1.42 kgf.m, 7.38-10.32 ft.lbf}
  5. Refill the engine coolant. (See «COOLING SYSTEM SERVICE WARNINGS [L3, AJ]»(ref-244562-S18278447982006092500000) ).

Removal

  1. Perform the following procedure to making the working space. Remove the Front wheel (RH). Remove the splash shield.
  2. Disconnect the CKP sensor connector.
  3. Remove the installation bolts to remove the CKP sensor.

Installation

CAUTIONWhen foreign material such as an iron chip is on the CKP sensor, it can cause abnormal output from the sensor because of flux turbulence and adversely affect the engine control. Be sure there is no foreign material on the CKP sensor when replacing.

  1. Perform the following procedure so that piston No. 1 is at the top dead center. Remove the front drive shaft (RH). (See «FRONT DRIVE SHAFT REMOVAL/INSTALLATION [L3, L3 WITH TC]»(ref-244605-S25656314442006092500000) ). Remove the cylinder block lower blind plug and install the SST . Turn the crankshaft pulley to the clockwise until it stops.
  2. Install the CKP sensor to the CKP sensor installer.
  3. Fit the forked part of the CKP sensor installer with the fifth tooth (counting counterclockwise from the empty space A as shown in the figure) of the pulse wheel.
  4. Install the CKP sensor fitting bolts. Tightening torque 5.5-7.5 N.m {56-76 kgf.cm, 4.1-5.5 ft.lbf}
  5. Remove the CKP sensor installer
  6. Remove the SST then install the cylinder block lower blind plug. Tightening torque 20 N.m {2.0 kgf.m, 15 ft.lbf}
  7. Install the front drive shaft (RH). (See «FRONT DRIVE SHAFT REMOVAL/INSTALLATION [L3, L3 WITH TC]»(ref-244605-S25656314442006092500000) ).
