FAULT DIAGNOSIS
1. IGNITION : Position 1
2. Left Temperature selector wheel : HI
Right Temperature selector wheel : LO
3. Within 20 seconds press the REST and EC buttons simultaneously for more than 5 seconds.
4. The LED in the RECIRCULATE button flashes and "dI R" appears on the display
5. Press the right AUTO button until all DTC's are displayed and recorded.
6. To erase all codes must be read out. Press both AUTO buttons simultaneously for more than 2 seconds. "d"
will be displayed on the left and "FF" is displayed on the right. The erase can be canceled by pressing the
AUTO.
7. Reset temperature selector to normal setting.
8. IGNITION : OFF to end the test program.
