E2 ETM
Hazard Indicator
Differential Lock Indicator
If the Hazard Switch (X220) is depressed, a pulsing
voltage is applied to the Hazard Indicator which is
permanently grounded by ground E200.
The Differential Lock Indicator receives battery
voltage with the Ignition Switch (X134) in position
II. It is grounded by the Differential Lock Switch
(X238) when the Differential is locked.
Direction Indicator
Fasten Seat Belt Indicator
(Except Japan Vehicles Only)
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.
The Fasten Seat Belt Indicator receives battery
voltage with the Ignition Switch (X134) in position
II. The indicator is also grounded through the Multi–
Function Unit (MFU) (Z148) and the Driver’s Seat
Buckle Switch (X120). If the Driver’s Seat Belt is
buckled the Driver’s Seat Belt Buckle Switch opens
and the Indicator turns off.
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 Module (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 sender’s resistance falls
below approximately 25 Ohms (6 liters/1.5 US
gallons), the Low Fuel Warning Indicator will
illuminate to warn the driver.
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.
Catalyst Warning Indicator
(Japan Vehicles Only)
In case of a catalyst overheat, the catalyst
thermocouples send a signal to the Catalyst
Warning ECU’s which then provide battery voltage
to the Catalyst Warning Relay (K172). The relay is
energized and provides ground to the Catalyst
Warning Indicator. The Catalyst Warning Indicator
is also grounded by a 3 second timer as a bulb
check.
