Diagnostic Procedure

DTC B119F:13 DIAGNOSTIC PROCEDURE

Step	Inspection		Action
1	INSPECT GPS ANTENNA CONNECTOR CONDITION Switch the ignition off. Disconnect the negative battery terminal. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION .) Disconnect the GPS antenna connector. Inspect the connector engagement and connection condition and inspect the terminals for damage, deformation, corrosion, or disconnection. Is the connector normal?	Yes	Go to the next step.
1		No	Repair or replace the connector, then go to Step 5.
2	INSPECT CONNECTIVITY MASTER UNIT (CMU) CONNECTOR CONDITION Disconnect the connectivity master unit (CMU) connector. Inspect the connector engagement and connection condition and inspect the terminals for damage, deformation, corrosion, or disconnection. Is the connector normal?	Yes	Go to the next step.
2		No	Repair or replace the connector, then go to Step 5.
3	INSPECT GPS ANTENNA CIRCUIT FOR OPEN CIRCUIT Verify that the GPS antenna and connectivity master unit (CMU) connectors are disconnected. Inspect the wiring harness for continuity between connectivity master unit (CMU) terminal 5A (wiring harness-side) and GPS antenna terminal A (wiring harness-side). Is there continuity?	Yes	Go to the next step.
3		No	Refer to the wiring diagram and verify if there is a common connector between connectivity master unit (CMU) terminal 5A and GPS antenna terminal A. If there is a common connector: Inspect the common connector and terminals for corrosion, damage, or disconnection and the common wiring harnesses for an open circuit to determine the malfunctioning location. Repair or replace the malfunctioning location. If there is no common connector: Repair or replace the wiring harness which has an open circuit. Go to Step 5.
4	VERIFY IF MALFUNCTIONING LOCATION IS GPS ANTENNA DEPENDING ON REPEATABILITY Always reconnect all disconnected connectors. Connect the negative battery terminal. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION .) Clear the DTC for the connectivity master unit (CMU) using the M-MDS. (See CLEARING DTC [CONNECTIVITY MASTER UNIT] .) Switch the ignition ON (engine off or on) and wait for 7 s or more. Retrieve the connectivity master unit (CMU) DTCs using the M-MDS. (See DTC INSPECTION [CONNECTIVITY MASTER UNIT] .) Is the same DTC displayed?	Yes	Replace the GPS antenna, then go to the next step. (See GLOBAL POSITIONING SYSTEM (GPS) ANTENNA REMOVAL/INSTALLATION .)
4		No	Go to Step 6.
5	VERIFY THAT REPAIRS HAVE BEEN COMPLETED Always reconnect all disconnected connectors. Connect the negative battery terminal. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION .) Clear the DTC for the connectivity master unit (CMU) using the M-MDS. (See CLEARING DTC [CONNECTIVITY MASTER UNIT] .) Switch the ignition ON (engine off or on) and wait for 7 s or more. Retrieve the connectivity master unit (CMU) DTCs using the M-MDS. (See DTC INSPECTION [CONNECTIVITY MASTER UNIT] .) Is the same DTC displayed?	Yes	Repeat the inspection from Step 1. If the malfunction recurs, replace the connectivity master unit (CMU). (See CONNECTIVITY MASTER UNIT (CMU) REMOVAL/INSTALLATION .) Go to the next step.
5		No	Go to the next step.
6	VERIFY IF OTHER DTCs DISPLAYED Are any other DTCs displayed?	Yes	Repair or replace the malfunctioning part according to the applicable DTC troubleshooting. (See DTC TABLE [CONNECTIVITY MASTER UNIT] .)
6		No	DTC troubleshooting completed.
