• BLUE - Connection / Communication indication
Figure 4-2 LEDs
LED indicator descriptions:
•
GREEN
– Off - CSM is not being powered
– On Continuous - CSM has power, but is not communicating
– Flashing - CSM has power, and is communicating
• RED
– Off - normal state, no errors detected
– On Continuous - communications error detected
– Flashing - internal self-test in process, will go out once the test completes
• BLUE
– Off - no connection
– On Continuous - USB cable connected and communicating
– Flashing - wirelessly connected and communicating
4.4 Audible Alerts
In addition to onscreen messages, the CSM uses audible tones to alert you of
connection status. Alerts include:
• Initial power on - (single 100ms “beep”)
• Communication terminated, CSM still connected to vehicle DLC - (After losing
communication, will continuously beep at two different frequency's every 10
seconds.)
• Communication terminated with diagnostic tool (out of range) - (After losing
communication, will continuously beep at two different frequency's every 10
seconds.). Diagnostic tool will also display a message “trying to re-establish
communication”, see Out of Range Alarm on page 41.
If other alerts occur (series of “beeps”) this may indicate a communication error.
Follow the onscreen instructions, to identify and resolve the issue.
4.5 LED Flashlight (built-in)
A built-in LED flashlight is provided to assist in illuminating dark areas in the vehicle
to find the DLC.To operate the light, press and hold the switch (see Figure 4-1 for
location).
The LED is powered by a built-in (non-replaceable) battery, and automatically
charges when the CSM is supplied power.
4.6 Basic Operation
4.6.1 Connecting the CSM
To use the Compact Scan Module (CSM), it must be powered, paired to the
diagnostic tool and connected to the vehicle DLC. To pair the CSM, see Pairing The
Scan Module on page 59. For power source information see, Power Source on
page 34.
z To connect the CSM to OBD-II vehicles:
1. Connect the CSM directly to the vehicle DLC.
2. Proceed to Basic Scanner Operation (Quick Start) on page 44.
An optional CSM extension cable DA-4EX is available to allow an extended
connection of the CSM to the vehicle DLC.
