Circuit/System Testing
- Disconnect the GPS antenna coax cable from the CIM. Refer to Antenna Coaxial/Connector Cable Identification Table .
- Ignition ON, test for 4.5-5.5 V between the CIM coax cable center conductor terminal at the module and ground.
- If not within the specified range, replace the CIM.
- Reconnect the coax cable to the CIM. Disconnect the coax cable from the GPS antenna.
- Test for 4.5-5.5 V between the coax cable center conductor and the outer shield.
- If not within the specified range, replace the coax cable.
- If all circuits test normal, replace the GPS antenna.
