nd
connector from the LEFT, “MON-NTC”! This is temp
sensor NTC #3.
b) Based on the [ Temperature ] window, TWO (2) possible
scenarios:
1) IF (and ONLY if) LESS THAN 30.0° C: See procedure number T- 1.0.131 (page 225).
2) IF MORE THAN 30° C: If
ABSOLUTELY SURE
the connector at the
2
nd
position from the
LEFT, “MON-NTC”, is unplugged AND [ Temperature ] is STILL more than 30.0° C proceed to
page
244
, procedure number T- 1.4.0 .
T- 1.0.131 [TEMPERATURE] WINDOW LESS THAN 30.0° C
a) Return NTC #3’s connector to the
