Power Mirror Control Module: Description and Operation

(C/M CM)

(SCM) (SLCM)

The Column/Mirror Control Module controls the operation of position adjustment motors by acting upon inputs from the relevant switches.The module also forms an interface with signals from associated systems which affect column/mirror movement. The C/M CM works in conjunction withSeat Control Module and Security/Locking Control Module to provide positional adjustment memory functions as previouslydescribed.

There are three connectors to the C/M CM single multi-pin socket, designated block A, B and C, which connect the various inputs/outputs and peripheraldevices to the module. Connections are as listed below.

Electronic Brake Control Module: Description and OperationDescription

DESCRIPTION

The ABS/TC CM is located beneath the modulator valve block and is secured by two screws. The CM houses the solenoids which operate the inletand outlet valves of the modulator valve block. When fitted, the valve stems locate in the CM mounted solenoids. The only electrical connectionbetween the CM and the modulator valve block is to the hydraulic pump. ABS /TC CM has nine solenoids.

OPERATION

The CM functions include the following:

- Providing control signals for the operation of ABS and traction control solenoid valves

- Calculating wheel speed from voltage signals transmitted by the wheel speed sensors

- Monitoring of all electrical components

-

On Board Diagnostics : storage of possible failures in a non-volatile memory.(OBD)

CONTROL SIGNALS

The signals from the four wheel speed sensors are independently processed by the ABS/TC CM, calculating numerical values which corresponddirectly to the wheel speed. These values are converted into control signals for pressure modulation during ABS control. The ABS and tractioncontrol are continuously monitored, while the ignition is on, for possible faults and interruptions. If a fault is detected, the module de-activates theABS and indicates this by lighting the ABS warning lamp. In a fault condition, conventional braking is unaffected. The module stores fault codesin a non-volatile memory which can be read via the OBD link.

Electronic Brake Control Module: Description and OperationHydraulic Operation

INDIVIDUAL PRESSURE MODULATION

ABS/TC CM hydraulic modules incorporate inlet valves (items 16 and 17) and outlet valves (items 20 and 21) for each driven wheel. This enablesindividual pressure modulation to the rear brakes under wheel spin conditions, i.e. traction control.

Increased Wheel Spin

- of a driven wheel under acceleration causes the NO isolation valve (item 14) to be closed and the pump (item 10) to beswitched on. This is in response to signals from the control module.

Closing Of The Isolation Valve Blocks

- delivery of the pump to the secondary circuit (item 2) of the TMC. The pump now draws fluid from thereservoir via the open hydraulically operated inlet valve (item 13). Increased pressure is now available at the inlet valves (items 16 and 17) foractuating the rear brakes, thus decreasing the tendency of wheel spin.

Description > Page 53

XJ-6L (X300) L6-4.0L (AJ16) (1997)

NOTE:

The hydraulic inlet valve (item 13) switches When traction control is initiated to change the suction connection of the pump from theaccumulators (item 9) to the fluid reservoir (item 6) via the TMC.

The Pressure At The Inlet Valves

- corresponds to the opening pressure of the relief valve (item 15) incorporated in the isolation valve. Excessbrake fluid is drained to the suction side of the pump via the relief valve and returns either to the TMC secondary circuit and on to the fluidreservoir, or is directly drawn on by the pump.

As The Spinning Wheel Has Been Braked

- down into the normal range of wheel spin, the NO valves (items 16 or 17) close to prevent anyfurther increase in brake pressure. Depending upon the acceleration of the wheel, the NC valve (item 20 or 21) may open to decrease thesecondary circuit brake pressure. NC valves (item 17 or 18) may remain closed in order to achieve a brake pressure holding phase. If the pressurein the secondary circuit needs to be increased again, the NC valve closes again (if open) and the NO valve opens, diverting the necessary volumeflow. This control action, keeps the wheel in the range of optimum slip until the spinning tendency ceases. The isolation valve (14) remains closed

throughout the traction control cycle.

Actuation Of The Brake By The Driver

- sensed by the control module, causes the traction control mode to be terminated and the isolation valve(item 14) to be opened. The TMC pressure simultaneously closes the hydraulic inlet valve (item 13) so that the pump can no longer draw fluidfrom it. The ABS/TC CM now operates in normal ABS mode.

NOTE:

When traction control is initiated, speed control is de-activated (if in operation) and requires re-setting after the traction control mode hasterminated. Gear shift is inhibited on automatic transmission vehicles; no downshifts are allowed and upshifts occur at 4800 RPM.

(SCCM)

The Speed Control Control Module , located behind the fascia, adjacent to the steering column, provides system control and an interface toexternal input signals from the instrument pack, gear selector module, traction control system, control switches, and foot pedal switches. The set speedvalue is retained in SCCM memory and continuously compared to actual vehicle speed. Adjustments are made, as necessary, to maintain set speed bycontrol of the vacuum pump and control valve.

Control Module HVAC: Description and OperationControl Module Fault & Condition Self-Analysis

System Health
System Health

The climate control system has a 'self-test' facility, accessible from the control panel. The self test sequence has two basic modes:

-

(A/CCM)

five (5)seconds

System error information is stored in the Air Conditioning Control Module up to a maximum of five faults. Should a sensor fault occur(Codes 11 to 21) there will be an audible 'beep' and the message 'Er' will be displayed on the control panel LCD for approximately after ignition on. Please note that this will happen only once in any ignition switch cycle. The error source may be accessed by theprocedure described in 'Self Test System Diagnosis'.

-

Panel Communication Check may be initiated by following the instruction in Testing and Inspection/Procedures/System Self-Test.

NOTE: (JDE)

Displayed error codes are NOT directly related to Jaguar Diagnostic Equipment but more detailed fault related information may beaccessed using Portable Diagnostic Unit .(PDU)

System Protection

Power to the compressor clutch may be cut should either the engine management or air conditioning control systems detect certain conditions; theseconditions may be caused by Fault or Demand and can be classified thus:

Fault

- Engine coolant overheat.

- Refrigerant excessive pressure.

- Refrigerant, insufficient pressure or low charge weight.

­Speed differential between compressor and crankshaft caused by belt slippage or compressor seizure (indicated by A/C state lamp flashing onceper second)-12 cylinder engine only. This feature is called, 'lock sensing'.

Demand

- Engine maximum power requirement

- Electrical system drain at engine idle.

Control Module HVAC: Description and OperationEngine Speed Signal
Engine Speed Signal

The Air Conditioning Control Module receives an engine speed signal from the Engine Control Module .(A/CCM) (ECM)

This signal facilitates compressor lock sensing (12 cyl. vehicles only).

800 RPM

This signal also aids the A/CCM inhibition of the heated screen relays. At engine speeds lower than the A/CCM assumes poor idle or enginenot running and will not permit the selection of the heated screens.
