• IF less than 0.5 volts DC: Measure at pin 6 (next row in table)
• IF more than 0.5 volts DC: Bad Actuator-Test Board (see page 9).
• IF less than 4.5 volts DC: See procedure number
• IF more than 5.2 volts DC: See procedure number
• IF between 4.5 and 5.2 volts DC: From debug screen 4, does LEAK = the
pin 6 measurement within +/- 0.3 volts DC?
Yes LEAK = pin 6 (+/- 0.3). Measure at pin 7 (next row in table).
No LEAK NOT within +/- 0.3 of pin 6 = Bad Sensor Board (see page 9).
• IF less than 4.0 volts DC: See procedure number
• IF more than 6.0 volts DC: See procedure number
• IF between 4.0 and 6.0 volts DC: From debug screen 4, does DIMN = the
pin 7 measurement within +/- 0.3 volts DC?
Yes DIMN = pin 7 (+/- 0.3). See procedure number
No DIMN does NOT within +/- 0.3 of pin 7= Bad Sensor Board (see page 9).
