A/C - 'Handbook Symbol' Displayed on ATC Display
Date: 27 February 2004
Automatic Temperature Control Fault
AFFECTED VEHICLE RANGE:
Range Rover (LP)
up to 2A427128
HANDBOOK SYMBOL ILLUMINATED ON THE ATC DISPLAY
When the coolant temperature reaches 97°C (207°F) and stays at or above that temperature for ten minutes, the Automatic Temperature Control (ATC)
diagnostic system will illuminate the handbook symbol on the ATC display. The diagnostic fault code in the ATC panel software is set too low for
normal vehicle operating conditions in very hot climates.
INSTALL RESISTOR TO ADJUST ATC INPUT
Installation of the resistor will "adjust" the displayed output temperature seen in real-time T4 monitoring. Comparing the ATC sensor output after the
modification with other coolant temperature information in real time can be misleading.
It is important to verify that there is not a mechanical cause for high coolant temperatures. Inspections for leaks and verification of the coolant level
as well as proper fan and thermostat operation should all be verified.
Should a customer express concern regarding the appearance of the handbook symbol during hot weather operation, the DTCs should be examined to
determine if the vehicle has a fault for the heater core temperature sensor. If that fault is flagged on vehicles built before the above VIN, follow the
rectification procedure in this TIB to install an in-line resistor link lead between the heater temperature sensor and the electrical harness.
Also refer to TIB 80/03/96/US for information relating to intermittent operation of early vehicle heater core sensors. Sensor date codes should be (April
1996) or higher.
