Diagnostic Trouble Code (DTC) Detecting Criteria
GENERAL DESCRIPTION
CX:DTC P0600 SERIAL COMMUNICATION LINK
1. OUTLINE OF DIAGNOSIS
Detect malfunction of CAN communication.
When CAN communications is not possible, and CAN communications with AT is not possible, judge as NG
if data from the AT is not normal.
2. COMPONENT DESCRIPTION
ECM and TCM are connected by high speed CAN.
(Common Specifications)
CAN Protocol 2.0 B (Active)
Frame Format: 11 Bit ID Frame (Standard Frame)
(High Speed CAN)
Conforms to ISO11898
Communication Speed: 500 kbps
3. ENABLE CONDITIONS
4. GENERAL DRIVING CYCLE
Perform the diagnosis continuously after starting the engine.
5. DIAGNOSTIC METHOD
Abnormality Judgment
When either of the following conditions are established, it is judged NG.
Judge as OK and clear the NG when the continuous time when all of the following criteria are established is
more than the predetermined time (1 second).
Time Needed for Diagnosis: 1 time
Malfunction Indicator Light: Illuminates as soon as a malfunction occurs.
6. DTC CLEAR CONDITION
•When the OK idling cycle is completed 40 times in a row
•When “Clear Memory” is performed
7. MALFUNCTION INDICATOR LIGHT CLEAR CONDITIONS
•When the OK driving cycle is completed 3 times in a row
•When “Clear Memory” is performed
8. FAIL SAFE
None
9. ECM OPERATION AT DTC SETTING
Memorize the freeze frame data. (For test mode $02)
Secondary Parameters Enable Conditions
Battery voltage≥ 10.9 V
Starter switch OFF
Engine run
Judgment Value
Malfunction Criteria Threshold Value

GD(H6DO)-171
Diagnostic Trouble Code (DTC) Detecting Criteria
GENERAL DESCRIPTION
CY:DTC P0604 INTERNAL CONTROL MODULE RANDOM ACCESS MEMORY
(RAM) ERROR
1. OUTLINE OF DIAGNOSIS
Detect the malfunction of microcomputer (RAM). Zero clear all normal RAM areas with the initial routine, and
Judge as NG when the sum of all added RAM after clearing is more than $0000.
2. ENABLE CONDITIONS
Diagnosis with the initial routine.
3. GENERAL DRIVING CYCLE
Perform the diagnosis as soon as the ignition switch is turned to ON.
4. DIAGNOSTIC METHOD
Judge as NG when the malfunction criteria below are met. Judge as OK and clear the NG when the malfunc-
tion criteria below are not met.
Time Needed for Diagnosis: Undecided
Malfunction Indicator Light: Illuminates as soon as a malfunction occurs.
5. DTC CLEAR CONDITION
•When the OK idling cycle is completed 40 times in a row
•When “Clear Memory” is performed
6. MALFUNCTION INDICATOR LIGHT CLEAR CONDITIONS
•When the OK driving cycle is completed 3 times in a row
•When “Clear Memory” is performed
7. FAIL SAFE
None
8. ECM OPERATION AT DTC SETTING
Memorize the freeze frame data. (For test mode $02)
Secondary Parameters Enable Conditions
None
Judgment Value
Malfunction Criteria Threshold Value
Zero clear all normal RAM areas. Result
of sum of all RAM after clearing
Not = 0
