Reading and Clearing Diagnostic Trouble Codes
1. DIAGNOSIS FUNCTION
a. Diagnosis start-up
For shifting to diagnosis mode, turn the ignition switch ON and push the "DISC" switch 3 times while pressing "ch1" and "ch6" switches.
HINT: To exit the diagnosis mode, push the "DISC" switch for 1.7 sec. or turn the ignition switch to ACC or OFF.
b. Element check mode
After the diagnosis start-up, the system enters the element check mode. Check that the all elements come on.
HINT: By pressing the "TUNE UP" switch, the system enters the "Service Check Mode".
c. Switch check mode
1. Element check mode is started at the same time with the switch check mode.
2. Check that there is a beep sound when any switch is pressed.
HINT: By pressing "TUNE UP" switch, the system enters the "Service Check Mode".
d. Service check mode
1. After the element check and the switch check are completed, the system enters service check mode when "TUNE UP" switch is pressed.
2. Error codes over the tuner and connected equipments are displayed on the screen of the tuner. Results for each check are displayed as follows:
- good:
No DTC is detected for both "System Check Confirmation" and "Diagnosis Memory Response".
- nCon:
The component does not respond to the "Diagnosis On Instruction" command.
Applicable to only the system where connected components are limited to be used.
- ECHn:
Application of new version is confirmed by the "Diagnosis On Check", and there is one or more DTC which indicates "Replacement" in the "System Check Result Response" or "Diagnosis Memory Response".
- CHEC:
Application of new version is confirmed by the "Diagnosis On Check", and there is no DTC which indicates "Replacement" in the "System Check Result Response" or "Diagnosis Memory Response", but one or more DTC which indicates "Check" is identified.
- Old:
Application of old version is confirmed by the "Diagnosis On Check", and DTC is identified in the "System Check Result Response" or "Diagnosis Memory Response".
- nrES:
No response is identified to the "System Check Start Instruction" and "Request for System Check Result" commands.
HINT:
- Check the present and past condition of components by performing the System Check and collecting stored DTC memories.
- Check results are displayed as one of the following six indications: "good", "ECHn", "CHEC","nCon", "Old" or "nrES".
e. Display Screen for Service Check.
Example:
Connection parts (physical address): Radio receiver (P190), RSA ECU (P1 F4), DVD player (P1AO)
f. "ECHn" Detail Display Mode Screen
g. "CHEC" Detail Display Mode Screen
h. "Old" Detail Display Mode Screen

- CHEC:
Application of new version is confirmed by the "Diagnosis On Check', and there is no DTC which indicates "Replacement" in the "System Check Result Response" or "Diagnosis Memory Response", but one or more DTC which indicates "Check" is identified.
- Old:
Application of old version is confirmed by the "Diagnosis On Check", and DTC is identified in the "System Check Result Response" or "Diagnosis Memory Response".
- nrES:
No response is identified to the "System Check Start Instruction" and "Request for System Check Result" commands.
HINT:
- Check the present and past condition of components by performing the System Check and collecting stored DTC memories.
- Check results are displayed as one of the following six indications: "good", "ECHn", "CHEC","nCon","Old" or "nrES".
