Issues & Causes/Solutions: VCM 2 & Temperature

VCM 2 unit is housed in a shock resistant polycarbonate case with rubber end boots, along with an extended operating temperature and voltage range, for increased durability and ruggedness in service bay and road test environments,

BUT do ensure the VCM II is not subjected to extreme temperature or prolonged exposure to direct sunlight that may cause heating of the VCM II.

Environmental requirement: Temperature & Humidity
Operating:
VCM II unit: -20ºC to 70ºC (-4ºF to 158ºF)
Wireless USB 2.0 adapter: 0ºC to 50ºC (32ºF to 122ºF) at 10% to 90% RH non-condensing

Storage: -40ºC to 85ºC (-40ºF to 185ºF) at 10% to 90% RH non-condensing


Issues & Causes/Solutions: VCM 2 & Temperature

Issue:
VCM II turns off (shutsdown/suspends-operation, all LEDs off) immediately after being powered by the USB cable or DLC cable

Cause/Solution:

• Verify the ambient temperature is within the acceptable operating range for the VCM II device: -20°C to 70°C (-4°F to 158°F)
• If the ambient temperature is outside this range allow the temperature to return to the acceptable operating range and the VCM II will automatically resume operation
• If VCM II error persists when the ambient temperature returns to its operating range, contact your regional technical support

Issue:
VCM II does not appear in the list of detected wireless devices in IDS and  its Power LED blinks at a periodic rate

Cause/Solution:

• Verify the VCM II is connected to the DLC cable and the DLC cable is connected to the vehicle. The VCM II must be powered using the DLC cable for the wireless interface to be operational
• Verify the ambient temperature is within the acceptable operating range for the VCM II's wireless interface: 0°C to 50°C (32°F to 122°F)
• If the ambient temperature is outside this range allow the temperature to return to the acceptable operating range and the VCM II's wireless interface will automatically be enabled and the Power LED will stop blinking and stay illuminated
• If VCM II wireless interface problem persists when the ambient temperature returns to its operating range, contact your regional technical support

Issue:
VCM II's Power LED blinks continuously after being powered using the DLC cable

Cause/Solution:

• Verify the ambient temperature is within the acceptable operating range for the VCM II's wireless interface: 0°C to 50°C (32°F to 122°F)
• If the ambient temperature is outside this range allow the temperature to return to the acceptable operating range and the VCM II's wireless interface will automatically be enabled and the Power LED will stop blinking and stay illuminated
• If VCM II wireless interface problem persists when the ambient temperature returns to its operating range, contact your regional technical support or ask obdexpress.co.uk for help
