DIAGNOSTIC TROUBLE CODES Detecting Conditions

If one of the following conditions continues for .48 seconds or more, one of these DTCs may set.

• Recovery prohibit run pulse is not output, solenoid relay is on, voltage at ABS/TRAC ECU terminal AST is 8 volts or more, and solenoid output has not changed between 2 circuit checks.
• Solenoid output is on, pressure holding solenoid voltage is more than one volt or pressure reduction solenoid voltage is more than 1.5 volts.
• Solenoid output is off and solenoid voltage at ABS/TRAC ECU terminal AST is more than minus one volt.
