OBTAINING FAULT CODES
(1) Connect the voltmeter or multi-use tester to the connector
for diagnosis.
(2) Read the output fault codes.
Then follow the remedy procedures according to the
“FAULT CODE DESCRIPTION” on the following page.
NOTE
l
As many as a maximum of ten fault codes, in the
sequence of occurrence, can be stored in the Random
Access Memory (RAM) incorporated within the control
unit.
l
If the number of stored fault codes or fault patterns
exceeds ten, already stored fault codes will be erased,
in sequence beginning with the oldest.
l
Do not disconnect the battery until all fault codes or
fault patterns have been read out, because all stored
fault codes or fault patterns will be canceled when the
battery is disconnected.
(3) If the fail-safe system is activated and the transaxle is
locked in 3rd gear, the fault code in the Fail-Safe Code
Description will be stored in the RAM.
Three of these fault codes can be stored.
(4) The cancellation will occur if, with the transaxle locked in
3rd gear, the ignition key is turned to the OFF position, but
the fault code is stored in the RAM.
