DCM Data Signal Circuit between Navigation ECU and DCM [08/2013 - ]: Procedure
- CHECK HARNESS AND CONNECTOR (DCM [TELEMATICS TRANSCEIVER] - MULTI-MEDIA MODULE RECEIVER ASSEMBLY)
- Disconnect the DCM (Telematics Transceiver) connector.
- Disconnect the multi-media module receiver assembly connector.
- Measure the resistance according to the value(s) in the table below.
Standard Resistance
