1. Measure:
• Thermoswitch input voltage
Out of specification → Check the wiring
harness.
Measurement steps:
1. Disconnect the thermoswitch coupler 1.
2. Push the unlock button, and then measure
the input voltage at the thermoswitch cou-
pler terminals (wiring harness end).
Thermoswitch input voltage (reference
data):
