Installing the CalAmp 3640 device
Step 3: Remove the dash panels
- Remove the lower dash panel from the passenger side of the vehicle (see purple arrow in image below).
- Remove the two 10mm bolts that retain the upper dash panel (see yellow arrows in image below).
- Remove the upper dash panel.
Step 4: Remove the CalAmp 423x device and cradle
- Depress the lock tabs to release the CalAmp 423x device from the plastic mounting cradle (see blue arrow in image below).
- Disconnect the HD15 pin cable using the thumb screws (see orange arrows in image below) and
let the HD15 cable head rest in place. You will need it later in the procedure.
If cable F39700 (Hino OBD-II) ships instead of the HD15, then technicians should connect the CalAmp device to the Hino's OBD-II port instead.
Step 5: Remove the CalAmp 423x mounting bracket
- Unscrew the 3 bolts that secure the CalAmp 423x mounting bracket using a 10 mm socket or wrench (see blue arrows in image below).
- Keep the bolts nearby to use again when you install the CalAmp 3640 mounting bracket.
Step 6: Attach the CalAmp 3640 mounting cradle
Attach the CalAmp 3640 mounting cradle to the CalAmp 3640 mounting bracket using the provided screws.
Step 7: Install the CalAmp 3640 mounting bracket
Slide the CalAmp 3640 mounting bracket in place and secure it using the three 10 mm bolts you removed at Step 3 (see blue arrows in image below).
A stamp on the mounting bracket shows the correct orientation for sliding it into place (see red area in image above).
Step 8: Connect the HD15 adapters
- Connect the supplied HD15 adapter end to the HD15 that you disconnected at Step 2.
If cable F39700 (Hino OBD-II) ships instead of the HD15, then technicians should connect the CalAmp device to the Hino's OBD-II port instead. - Connect the 16 pin Molex end to the CalAmp 3640 device.
Coil and secure any loose cabling using zip ties to ensure it will not interfere with passengers or normal operation of the vehicle.
Step 9: Mount the CalAmp 3640 device
Press the CalAmp 3640 device into the mounting cradle until the tabs lock it in place.
Step 10: Connect the CalAmp 3640 device
- Connect the CalAmp 3640 device.
- Note the LED colors and statuses (see descriptions below).
Green LED (GPS)
- Flashing: searching for GPS signal
- Solid: GPS signal is acquired
Amber LED (cellular network)
- Flashing: searching for cellular network signal
- Solid: cellular network signal is acquired
Step 11: Reinstall the dash panels
Reinstall all the dash panels and screws that you removed during the disassembly process as follows:
- Reinstall the upper dash panel on the passenger side of the vehicle.
- Reinsert the two 10mm bolts in the upper dash panel (see yellow arrows in image below).
- Reinstall the lower dash panel (see purple arrow in image below).
Step 12: Verify operation
The two device LEDs (Amber for cellular network, green for GPS) must be solid before you verify operation of the device.
