Scheme 8: FLASHER CONTROL MODULE REMOVAL/INSTALLATION
  1. Remove the battery cover.
  2. Disconnect the negative battery cable. (See «BATTERY REMOVAL/INSTALLATION [LF]»(ref-244448-S25513985422006092400000) .)
  3. Disconnect the connector.
  4. Remove the screw and then remove the flasher control module.
  5. Install in the reverse order of removal.

FLASHER CONTROL MODULE INSPECTION

  1. Remove the flasher control module with the connector still connected.
  2. Measure the voltage at each terminal (other than terminal F). If the voltage is not as specified in «TERMINAL VOLTAGE TABLE»(ref-244511-S06432946452006092400000) inspect the parts under "Inspection item(s)".
  3. Disconnect the flasher control module connector.
  4. Verify that continuity at terminal F is as indicated in «TERMINAL VOLTAGE TABLE»(ref-244511-S06432946452006092400000) . If there is any malfunction, inspect the parts under "Inspection item(s)". If the system does not work properly even though the parts or related wiring harnesses do not have any malfunction, replace the flasher control module.
