WARNINGS AND INDICATORS (EXCEPT NAS) 1 ETM E2 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). 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) when the 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. Petrol 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. Diesel Glow Plug Indicator The Glow Plug Indicator is grounded by the Glow Plug Timer Unit (Z135) to indicate that the Glow Plugs have been activated.
WARNINGS AND INDICATORS (EXCEPT NAS) 2 E2 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 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 senders 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. TC Warning Light The TC warning light will be on for up to 60 seconds while the system is active. After 60 seconds of TC operation, the TC 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 TC warning light stays on continuously for more than 60 seconds, a fault in the system is indicated. The TC warning light receives battery voltage with the Ignition Switch (X134) in position II. A ground supply is provided by the A.B.S. ECU (Z108) when the TC system is active. 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.
