- The radio receiver assembly may not operate normally.
PROCEDURE
| 1. | CHECK HARNESS AND CONNECTOR (NO. 1 STEREO JACK ADAPTER ASSEMBLY ILLUMINATION POWER SOURCE) |
(a) Disconnect the G103 and G8 No. 1 stereo jack adapter assembly connectors.
| (b) Measure the voltage according to the value(s) in the table below. Standard Voltage:
|
|
| OK |  | REPLACE NO. 1 STEREO JACK ADAPTER ASSEMBLY |
|
| 2. | CHECK HARNESS AND CONNECTOR (RADIO RECEIVER ASSEMBLY - NO. 1 STEREO JACK ADAPTER ASSEMBLY) |
(a) Disconnect the G102 radio receiver assembly connector.
(b) Disconnect the G103 No. 1 stereo jack adapter assembly connector.
| (c) Measure the resistance according to the value(s) in the table below. Standard Resistance:
|
|
| NG | | REPAIR OR REPLACE HARNESS OR CONNECTOR |
|
| 3. | CHECK HARNESS AND CONNECTOR (RADIO RECEIVER ASSEMBLY - NO. 1 STEREO JACK ADAPTER ASSEMBLY) |
(a) Disconnect the G5 radio receiver assembly connector.
(b) Disconnect the G8 No. 1 stereo jack adapter assembly connector.
(c) Measure the resistance according to the value(s) in the table below.
