1. Measure the voltage and resistance according to the value(s) in the table below.

   Table 1. Standard voltage

   Tester Connection	Wiring Color	Terminal Description	Condition	Specified Condition
   D34-10 (FDF1) - D33-14 (GND)	R - W-B	Front deicer signal	Ignition switch on (IG), Front window deicer switch OFF	11 to 14 V
   			Ignition switch on (IG), Front window deicer switch ON	Below 1 V
   D33-1 (IG+) - D33-14 (GND)	GR - W-B	Power source (IG)	Ignition switch on (IG)	11 to 14 V
   			Ignition switch off	Below 1 V
   D33-21 (B) - D33-14 (GND)	B - W-B	Power source (Back-up)	Always	11 to 14 V

   Table 2. Standard resistance

   Tester Connection	Wiring Color	Terminal Description	Condition	Specified Condition
   D33-14 (GND) - Body ground	W-B - Body ground	Ground	Always	Below 1 Ω

   If the result is not as specified, there may be a malfunction in the wire harness or amplifier.
