Diagnostic procedure
STEP
1 VERIFY FREEZE FRAME DATA HAS BEEN
RECORDED
• Has FREEZE FRAME PID DATA been
recorded?
2 VERIFY RELATED REPAIR INFORMATION
AVAILABILITY
• Check for related Service Bulletins availability.
• Is any related repair information available?
3 CHECK ATF CONDITION
• Turn ignition key to OFF.
• Check ATF condition.
— Clear red: Normal
