Steering Satellite Switch: Inspection

Fig 1: Identifying Satellite Switch Connector Terminals

DIAGNOSIS PROCEDURE

Step	Check	Yes	No
1 CHECK MUTE SWITCH CONTINUITY. 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 CHECK VOLUME SWITCH CONTINUITY. 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. 190 Ω? (Volume down)	Go to step 3 .	Replace the satellite switch.
3 CHECK MODE SWITCH CONTINUITY. Press the MODE switch. Measure the resistance between satellite switch connector terminals. Terminals No. 1 - No. 2:	Is the resistance approx. 330 Ω?	Go to step 4 .	Replace the satellite switch.
4 CHECK SEEK SWITCH CONTINUITY. 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. 600 Ω? (Seek up) And is the resistance approx. 1.1 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.
