Description of the issue: the customer Ride Share (also known as Spark) reported that the vehicle does not react to lock/unlock commands properly, the car cannot be locked or unlocked. The system on the customer's side shows ATH_FAIL or similar error.
This article is applicable for vehicles that use ATH_INV installation method using 3 DOUTs to control Lock/unlock commands +1 DOUT for ATH (Ignition blocking). This includes but is not limited to:
Dacia Spring
Common causes:
Physical connection issue;
User mistake (Open doors/hood/hatch);
Incorrect LCV door state is received ("open doors");
Delayed or incorrect reception of "CAN door lock state";
Faulty CAN communication (rare case, needs to be investigated individually)
Troubleshooting steps:
1. Make sure the device is installed using the latest version of installation manual (no earlier than 1.2):
Check CFG version in CFG update module. It should help to determine the installation method (v1.0 may ot work properly, 1.1 should work more or less fine):
Earlier versions (1.0 and 1.1) had issues with CAN data reading and DOUT activation, therefore shall not be used. As of May 2022, it is the most common cause of the issue.
2. Try sending LOCK_BLOCK and UNLOCK_UNBLOCK commands using Jenkins platform (try to reproduce the issue).
3. In case the vehicle does not execute commands properly (ATH_FAIL is displayed), block the engine via Jenkins platform (send command BLOCK). DOUT2 should change to "1". This should be done for safety reasons.
4. In case the issue persists (you cannot lock/unlock the car via Jenkins), register a query and consult with EU Global support. Most likely, a JIRA case shall be registered for further investigation.
