14COOLANT TEMP.
VOLTAGE LOW· Coolant temperature higher than 140 °C / 282 °F (short circuit to ground)

· Above condition must be fulfilled for at least 1.0 s

Replacement values:

· With ignition On and trouble codes 69 and 71 not present, the intake air temperature is taken as the starting value.

· With ignition On and trouble code 69 or 71 present, 10 °C / 50 °F is taken as the starting value.

· If a plausible measured value has already been produced for the coolant temperature, it is used as the starting value

· The starting value is increased by 1 °C / 1.8 °F every 146 cycles (1 cycle = 720 °CA) to a maximum value of 99 °C / 211 °F.

This value is used for the remaining engine operation.

Effects:

· All adaptation except knock control, throttle valve control and idle speed adjuster control is blocked

· The tank vent valve regulation is blocked and the tank vent valve closed
