POSITION MEMORY CONTROL MODULE INSPECTION

id091300811200

1. Measure the voltage at each terminal is as indicated in the Terminal Voltage Tables.

  • If the voltage is not as specified in the Terminal Voltage Table (Reference), inspect the parts under "Inspection item(s)" and related wiring harnesses.

2. If the system does not work properly even though the inspection items or related wiring harnesses do not have any malfunction, replace the position memory control module.
