1# Location Subsystem Error Codes 2 3> **NOTE** 4> 5> This topic describes only module-specific error codes. For details about universal error codes, see [Universal Error Codes](errorcode-universal.md). 6 7## 3301000 Location Service Unavailable 8 9**Error Message** 10 11Location service is unavailable. 12 13**Description** 14 15This error code is reported when the location service is unavailable and relevant APIs cannot be called. 16 17**Possible Causes** 18 191. The location service fails to be started. As a result, the communication between the application and the location service fails, and the location service is unavailable. 20 212. The GNSS chip fails to be initialized, and thus the GNSS positioning function becomes invalid. 22 233. The network positioning service is abnormal, and thus the network positioning function becomes invalid. 24 25**Solution** 26 27Stop calling the API. 28 29## 3301100 Location Service Unavailable Because of Switch Toggled Off 30 31**Error Message** 32 33The location switch is off. 34 35**Description** 36 37This error code is reported when the location service is unavailable because the service switch is toggled off. 38 39**Possible Causes** 40 41The location service switch is toggled off, which makes basic functions such as continuous positioning and immediate positioning unavailable. 42 43**Solution** 44 45Display a prompt asking for enabling the location service. 46 47## 3301200 Failure to Obtain the Positioning Result 48 49**Error Message** 50 51Failed to obtain the geographical location. 52 53**Description** 54 55This error code is reported when the location service fails, and no positioning result is obtained. 56 57**Possible Causes** 58 591. Positioning timed out because of weak GNSS signals. 60 612. Positioning timed out because the network positioning service is abnormal. 62 63**Solution** 64 65Initiate a positioning request again. 66 67## 3301300 Reverse Geocoding Query Failure 68 69**Error Message** 70 71Reverse geocoding query failed. 72 73**Description** 74 75This error code is reported for a reverse geocoding query failure. 76 77**Possible Causes** 78 79Network connection is poor, which makes the request fail to be sent from the device or the result fail to be returned from the cloud to the device. 80 81**Solution** 82 83Try the reverse geocoding query again. 84 85## 3301400 Geocoding Query Failure 86 87**Error Message** 88 89Geocoding query failed. 90 91**Description** 92 93This error code is reported for a geocoding query failure. 94 95**Possible Causes** 96 97Network connection is poor, which makes the request fail to be sent from the device or the result fail to be returned from the cloud to the device. 98 99**Solution** 100 101Try the geocoding query again. 102 103## 3301500 Area Information Query Failure 104 105**Error Message** 106 107Failed to query the area information. 108 109**Description** 110 111This error code is reported for the failure to query the area information (including the country code). 112 113**Possible Causes** 114 115The correct area information is not found. 116 117**Solution** 118 119Stop calling the API for querying the country code. 120 121## 3301600 Geofence Operation Failure 122 123**Error Message** 124 125Failed to operate the geofence. 126 127**Description** 128 129This error code is reported when an operation (like adding, deleting, pausing, and resuming) fails to be performed on the geofence. 130 131**Possible Causes** 132 1331. The GNSS chip does not support the geofence function. 134 1352. The bottom-layer service logic is abnormal. 136 137**Solution** 138 139Stop calling the geofence operation API. 140 141## 3301700 No Response to the Request 142 143**Error Message** 144 145No response to the request. 146 147**Description** 148 149This error code is reported when no response is received for an asynchronous request that requires a user to click a button for confirmation or requires a response from the GNSS chip or network server. 150 151**Possible Causes** 152 1531. The user does not click a button as required for confirmation. 154 1552. The GNSS chip does not respond. 156 1573. The network server does not respond. 158 159**Solution** 160 161Stop calling relevant APIs. 162
