ABS valve control mode indicates "inactive" not "off" like v

Post by Ohhyesican »

Hello, working on 2008 Fusion ABS. Using Forscan in control mode to manually cycle valves in ABS system. The RF outlet valve indicates "inactive/active" instead of "off/on" like all other valves in system. Does this indicate a problem with comms to that valve, or perhaps that valve is defective? All other valves demonstrate an audible click when commanded on; the valve showing "inactive" does not. Also, valves only stay open for a few seconds when commanded open, is this by design or does ABS control module override and close?

Using with OBLink MX adapter.

Thanks for great software-

There is no principial difference between On/Off and Active/Inactive states. It is just a text representation of a PID state. Active means On and Inactive means Off. However, the fact it is different from other PIDs is quite weird, it may mean FORScan uses wrong PID (from other model, for example). You may make sure the command was successfully sent as the following:

1. Check Vehicle->Log. Result of operation with control PID is logged (successful or not).
2. Add read PID for the RF outlet valve and monitor it while changing the control PID (read PID should change accordingly).

If log says operation was successful and read PID changes as expected, it means the command is sent properly. However we recommend to send us FORScan logs for more thorough analysis (http://forscan.org/contactus.html, please send to email or PM)

No it is not by design, the actuators should de-activate (so control returned back from FORScan back the module) when operator close the Output control windows. If it happens earlier, it may indicate a problem managing the special diagnostic mode. Log analysis would answer to this question too.
