I recently purchased the CRP123 from Autointhe box.com

Boot Version: V02.04

Displays Program Version: V02.28

Diagnostic Program Version: V11.22

Diagnostic Library Version: V11.22

I got the tool registered successfully and also got the firmware and data downloaded sucessfully onto the tool. I have observed the following issues with the tool when I connect it to my vehicle (Mitsubishi Lancer, Model:CS3, Year of Manufacture: 2002, Country of Manufacture: Japan):

With engine idling in Neutral, and CRP123 Tool connected to the DLC, the following function does not work:

DIAGNOSE: The green communication LED never blinks, as the tool tries all its communication protocols, which report as 'fail, fail' fail ... as the tool tries to communicate with the ECU. After all communication protocols fail, the display says 'Cannot Enter'.
I am therefore unable to use the DIAGNOSE function on the CRP123 Tool.

I then try the SCAN function, and I get options to Read DTC, Clear DTC and Read Datastream from the Engine ECU, the A/T ECU, the SRS ECU, I am able to view the Datastream from the Engine ECU, the A/T ECU and the SRS ECU, but not from the ABS ECU.

I turn ON the RECORD feature and the CRP123 records several snapshots of the Datastream on the display. I use the Review Datastream option to review the recorded data.

I have observed two anomalies with the temperature readings:

AIR TEMP. S = 85 Deg.C : Question: should this be the Engine Coolant Temperature instead of the Inlet Air Temperature?

CLT TEMP.SNSR = 35.04 Deg.C: Question:should this be the Inlet Air Temperature, instead of the Coolant Temperature?

The recorded datastream from the A/T ECU indicates:

OIL TEMP.SNSR = 26.15 Deg. C, which is less than the prevailing ambient temperature of 30 Deg.C.

Also note that when the coolant is at ambient temperature (30 Deg.C) prior to starting the engine, the CLT TEMP.SNSR reading is 2.2 Deg.C, which is unrealistic, as I am located in a tropical climate.

So I have three temperature readings on the CRP123 Datastream which all seem to be incorrect or incorrectly read from the vehicle's ECU.


Please advise what actions should be taken to address these anomalies in the temperature readings, as well as the failure of the CRP123 tool to communicate via the DIAGNOSE function with the Engine ECU.

The communication protocols loaded onto the CRP123 are:

J1850 VPW
J1850 PWM
ISO 15765-4 CAN (11-bit)
ISO 15765-4 CAN (29-bit)
ISO 14230-4 KWP
ISO 14230-4 KWP (5BPS)
ISO 9141


All above protocols indicated 'fail' when "Entering System" dialog box was displayed, soon after the DIAGNOSE function was selected.

Can anyone suggest possible fixes for this problem? Thank you.
