STEERING SATELLITE SWITCH DIAGNOSTIC PROCEDURE CHART

Step	Check	Yes	No
1 MUTE SWITCH CONTINUITY CHECK. Press the mute switch. Measure the resistance between satellite switch connector terminals. Terminals No. 1 - No. 2:	Is the resistance approx. 22 Ω?	Go to step 2.	Replace the satellite switch.
2 VOLUME SWITCH CONTINUITY CHECK. Press the volume switch. Measure the resistance between satellite switch connector terminals. Terminals No. 1 - No. 2: Volume up No. 1 - No. 2: Volume down	Is the resistance approx. 90 Ω? (Volume up) And is the resistance approx. 200 Ω? (Volume down)	Go to step 3.	Replace the satellite switch.
3 MODE SWITCH CONTINUITY CHECK. Press the MODE switch. Measure the resistance between satellite switch connector terminals. Terminals No. 1 - No. 2:	Is the resistance approx. 360 Ω?	Go to step 4.	Replace the satellite switch.
4 SEEK SWITCH CONTINUITY CHECK. Press the seek switch. Measure the resistance between satellite switch connector terminals. Terminals No. 1 - No. 2: Seek up No. 1 - No. 2: Seek down	Is the resistance approx. 690 Ω? (Seek up) And is the resistance approx. 1.5 kΩ? (Seek down)	Go to step 5.	Replace the satellite switch.
5 CHECK SATELLITE SWITCH INSULATION. Not to operate the satellite switch. Measure the resistance between satellite switch connector terminals. Terminals No. 1 - No. 2:	Is the resistance approx. 4.7 kΩ?	Satellite switch is normal.	Replace the satellite switch.
