HINT:
- If the AWD warning light does not blink, perform relevant troubleshooting procedures. The relevant troubleshooting procedures are in the sections listed in the table below.
- When the system is operating correctly, each light will blink continuously in a pattern of 0.25 seconds on, then 0.25 seconds off.
- When one DTC is output, each lamp will output the same code at 4 second intervals. (For example, Code 21 would be output as 2 flashes, a 1.5-second pause, and then 1 flash).
- When 2 or more DTCs are output, each lamp will output a different code at 2.5-second intervals, and when all codes have been output, there will be a 4-second pause and the sequence will repeat.
- When multiple codes are set, they are output in order starting with the lowest DTC number.
(e) Refer to the Diagnostic Trouble Code Chart (See page
) for DTC information.
(f) After completing the check, turn the ignition switch off and remove SST from the DLC3.
