							WARNINGS AND INDICATORS (NAS)
1
ETM E3
1995 RANGE ROVER
ELECTRICAL TROUBLESHOOTING MANUAL
CIRCUIT OPERATION
Charge Warning Light
The charge warning light receives battery voltage
with the Ignition Switch (X134) in position II. This
warning light is grounded by the Generator (Z106)
if the Generator is not producing normal power
output or the Generator stops turning.
ABS Warning Light
The ABS warning light receives battery voltage with
the Ignition Switch (X134) in position II. It is
grounded by the Anti±Lock Brake System ECU
(Z108) or the ABS Warning Relay (K103) in the
event of an ABS problem.
Brake Warning Light
The brake warning light receives battery voltage
with the Ignition Switch (X134) in position II. It is
grounded by the Brake Fluid Level Switch (X111)
when the brake fluid level is low. It may also be
grounded through the Right Front and Right Rear
Inboard Brake Pads (B129, B155), and the
Handbrake Diode (Z197) when the Handbrake
Switch (X191) is closed. The warning light is also
grounded by the Anti±Lock Brake System ECU
(Z108) or by the ABS Pressure Switch Unit (Z104)
in the event of an ABS system problem.When the
Right Front or Right Rear Inboard Brake Pad
(B129, B135) is in need of replacement, the brake
warning light is grounded through the Right Front
or Right Rear Inboard Brake Pad (B129, B135).
The brake warning light is grounded by a 3 second
timer as a bulb check.
Oil Pressure Warning Light
The oil pressure warning light receives battery
voltage with the Ignition Switch (X134) in position
II. If the engine oil pressure is very low, the Oil
Pressure Switch (X149) will apply ground to the
warning light.
Transmission/Transfer Box Oil Temperature
Warning Light
The transmission/transfer box oil temperature
warning light is grounded by the Automatic
Transmission Oil Temperature Switch (X108) whenthe temperature of the transmission fluid exceeds
1305C (2665F). The warning light is also grounded
by the Transfer Box Oil Temperature Switch (X174)
when the temperature of the transfer box fluid
exceeds 1455C (2665F). The Bulb Check Relay
(K173) will illuminate the warning light when the
vehicle is first started to test the bulb.
Malfunction Indicator Lamp (Check Engine)
The Malfunction Indicator Lamp (Check Engine) is
grounded by the Engine Control Module (ECM)
(Z132) when a diagnostic trouble code is set.
Service Reminder Indicator
The Service Reminder Indicator receives battery
voltage with the Ignition Switch (X134) in position
II. The Service Reminder Unit (Z126) grounds the
Service Reminder Indicator when the vehicle
requires service. The Service Reminder Indicator is
also grounded by a 3 second timer as a bulb
check.

E3 ETM
1995 RANGE ROVER
ELECTRICAL TROUBLESHOOTING MANUA L
Hazard Indicator
If the Hazard Switch (X220) is depressed, a pulsing
voltage is applied to the Hazard Indicator which is
permanently grounded by ground E200.
Direction Indicator
If the Direction Indicator Switch (X116) is turned
on, a pulsing voltage is applied from the Flasher
Unit (Z128) to the Direction Indicator which is
permanently grounded by ground E200.
Trailer Indicator
With the Direction Indicator Switch (X116) turned
on, the Flasher Unit (Z128) also applies a pulsing
voltage to the Trailer Indicator which is permanently
grounded by ground E200.
SRS Indicators
The SRS Indicators are controlled by the Air Bag
Diagnostic Control Unit (Z151) and the SRS
Indicator Control Circuit of the Instrument Cluster
(Z142) to indicate SRS System faults.
Low Fuel Warning Indicator
When the fuel gauge senders resistance falls
below approximately 25 Ohms (6 liters/1.5 US
gallons), the Low Fuel Warning Indicator will
illuminate to warn the driver. The Low Fuel Warning
Indicator is grounded by a 3 second timer as a bulb
check.
Main Beam Indicator
With the Headlamps turned on the Main Lighting
Switch (X145), battery voltage is applied to the
Main Beam Indicator which is also permanently
grounded by ground E200.
ETC Warning Light
The ETC warning light will be on for up to 60
seconds while the system is active. After 60
seconds of ETC operation, the ETC warning light
will begin to flash to inform the driver that the
system has been shut down to allow the brakes to
cool. If the ETC warning light stays on continuously
for more than 60 seconds, a fault in the system is
indicated.
Air Suspension Indicator
If the Air Suspension ECU (Z165) detects a fault in
the system, the ECU will inform the driver by
intermittently grounding the Warning Lamp Relay
(K155) for 30 seconds. This causes the Air
Suspension Indicator to flash for 30 seconds. After
30 seconds the indicator will remain on until the
repair is made.
Fasten Seat Belt Indicator
The Fasten Seat Belt Indicator receives battery
voltage with the Ignition Switch (X134) in position
II. The indicator is also grounded through the
Multifunction Unit (MFU) (Z148) and the Drivers
Seat Buckle Switch (X120). If the Drivers Seat Belt
is buckled the Drivers Seat Belt Buckle Switch
opens and the Indicator turns off.
