Description of On-Board Diagnostics

SELF-DIAGNOSIS
- As many as ten diagnostic trouble codes, in the sequence of occurrence, can be stored in the Random Access Memory (RAM) incorporated within the control module.
- The same diagnostic trouble code can be stored just one time.
- If the number of stored diagnostic trouble codes or diagnostic trouble patterns exceeds ten, already stored diagnostic trouble codes will be erased, in sequence beginning with the oldest.
- Do not disconnect the battery until all diagnostic trouble codes or diagnostic trouble patterns have been read out, because all stored diagnostic trouble codes or agnostic trouble patterns will be canceled when the battery is disconnected.
- If the auto transaxle fluid temperature reaches 50°C or above 200 times from the initial memory, the fault code will be erased.
- If the fail-safe system is activated and the transaxle is locked in third gear, the diagnostic trouble code in the Fail-safe Code Description will be stored in the RAM. Three of these fault codes can be stored.
- The cancelation will occur if, with the transaxle locked in 3rd gear, the ignition key is turned to the OFF position, but the diagnostic trouble code is stored in the RAM.
