id091300702400
Simple Inspection
1. Place a cooling agent on the seat cushion (thermistor).
2. Operate the seat warmer switch to turn on the seat warmer.
3. Touch the seat cushion and the seat back to verify a temperature increase.
4. If a temperature increase cannot be verified, go to the resistance inspection. (See Resistance Inspection (VIN : JMZ TB*****# 500001-699999, JM5 TC*****# 200001-399999, JM7 TC*****# 200001-399999).)
