Land Rover Defender Puma Analog Cluster Adapter

Setup

The adapter is set up in the GoSwap app from a phone over a USB Type-C cable. Changes are sent to the adapter with the “APPLY” button at the bottom of the screen — the number on it shows how many settings have changed. The new value takes effect at once, no adapter restart needed.

1. 1

   Connect the phone.

   Install the GoSwap app — app page (goswap.kz/en/cfg/). Turn on the ignition, connect the phone and the adapter with a USB Type-C cable, choose “USB” in the app and tap “Connect”.

   
2. 2

   Temperature sensor — TEMP° tab.

   In “Coolant temp sensor” choose which sensor is fitted and how it is connected: “Land Rover” — the stock Td5 sensor in parallel with the unit, “Toyota” — the stock sensor of a Toyota engine in parallel with the unit, “Bosch” — a separate 0 281 002 209 sensor for the adapter only. Do not choose “Bosch” with the stock sensor: the engine control unit will see the engine colder than it is.

   “Sensor calibration” — on a warm engine: compare the “Coolant temp” tile with the temperature the engine control unit shows in diagnostics. The tile shows less — increase the value by the difference, more — decrease it, then “APPLY”. The cluster needle moves together with the tile.

   

Setup

1. 3

   Tachometer — TACH tab.

   “Pulses per revolution” — how many tachometer pulses there are per engine revolution, 2.0 by default for Td5. At idle compare the “RPM” tile with the engine control unit RPM in diagnostics: the tile shows half — halve the value, double — double it. Then “APPLY” and check at different RPM.

   
2. 4

   Lamps — LAMPS tab.

   “Oil pressure sensor”: almost all sensors are “Closed” — with no pressure the contact is closed to ground. Check: ignition on, engine stopped — the oil pressure lamp on the cluster is on, after starting it goes out. If it is the other way round — choose “Open”.

   “Charge lamp”: “D+ terminal” — by the D+ [19] wire from the alternator, “Voltage” — by vehicle voltage, no wire to the alternator needed.

   “Charge threshold” — only for “Voltage”: with the engine running, voltage below the threshold for more than 5 seconds turns the lamp on, 0.3 V above the threshold turns it off; while the engine is not turning, the lamp is on. Start at 12.5 V and adjust by the “Voltage” tile at the top of the tab: with the engine running under load — headlights, fan — it should be at least 0.3 V above the threshold.

   

Setup

1. 5

   Check — LIVE tab.

   The tiles show what the adapter reads from the engine and sends to the cluster right now:

   • “Cluster” — a check mark: the cluster is talking over CAN. A cross — check the bus: CAN H [15] and CAN L [3] must not be swapped, resistance between them with the battery disconnected — 60 Ω.
   • “RPM” — from the tachometer TACH [22], the same as sent to the cluster. Zero with the engine running — check the TACH [22] wire; differs from diagnostics — adjust “Pulses per revolution” (step 3).
   • “Coolant temp” — temperature from the TEMP [24] sensor, with calibration applied: the cluster needle shows the same. If the sensor is open or shorted, the needle goes to the overheat zone.
   • “Voltage” — voltage at the adapter itself, normally 12–15 V. It also depends on the ground: lower than at the battery — check ground GND [1] and power +IGN [13].
   • “Check Engine”, “Glow plugs”, “Charge lamp” and “Oil pressure” — the circle lights up when the lamp is on in the cluster; the signals come from the CHECK [17], GLOW [18], D+ [19] and OIL [20] wires. Ignition on, engine stopped — “Charge lamp” and “Oil pressure” are on, after starting they go out.
