Diagnostic Switch
Blink Codes – System Configuration and System Faults.
By properly actuating the ABS diagnostic button,
configuration codes and diagnostic trouble codes can be
retrieved as blinked sequences on the ABS indicator lamp.
Configuration codes are sequences of four blinked digits
while diagnostic trouble codes appear as two blinked
numbers. Refer to the charts beginning on page 19 for a
description of these codes. To perform any of the activities
listed below, simply follow the steps as given. If you make
a mistake during one of the steps, stop and start over at the
beginning of the procedure.
All blink codes are displayed by the ABS indicator lamp
only. The ATC lamp does not display blink codes.
Note: Before attempting any repairs:
1. Retrieve the configuration codes and diagnostic trouble
codes (write them down).
2. Reconfigure the ECU if the configuration does not agree
with the installed hardware. The ECU cannot be
configured downward (components removed) with the
diagnostic button. For example, a 6S-4M cannot be
configured to 4S-4M. Downward configurations require
the use of a ProLink tool or ServiceRanger software.
3. If the configuration is correct, clear the diagnostic trouble
codes. The process for clearing the trouble codes and
reconfiguring the ECU is the same when using the
diagnostic button.
4. Once again retrieve the diagnostic trouble codes. Only
active codes will now be displayed.
