Data Parameters Engine Parameters

CAMSHAFT SIGNAL, RIGHT BANK

CAMSHAFT SIGNAL, LEFT BANK

Range: __________________________________________________________ YES/NO

Used on ME27 and ME28 systems. These parameters indicate whether there are camshaft

signals from the left and right engine banks.

CAMSHAFT SOLENOID

Range: __________________________________________________________ ON/OFF

Used on HFM systems. This parameter indicates whether the camshaft solenoid is on or off.

CAN DATA EXCHANGE

Range: __________________________________________________________ YES/NO

Used on DM and DM2 systems. This parameter indicates whether the controller area network

(CAN) bus data exchange signal is active or not active.

The CAN is a broadcast type of bus. This means that all modules “hear” all transmissions. There

is no way to send a message to just a specific module; all modules invariably pick up all traffic.

However, CAN hardware provides local filtering so each module reacts only to data whose

identifiers are stored in its acceptance list. This very high frequency transmission requires a

“twisted pair” of wires to address electromagnetic interference (EMI) concerns. Two wires also

ensure communication if one wire is damaged and provide the ability to recognize a CAN circuit

fault. The two lines must not be interchanged as each represents either high or low level.

CAN RECEPTION FROM ASR

Range: _______________________________________________________ OK/NOT OK

Used on EZ systems. This parameter indicates if the controller area network (CAN) is receiving

data from the acceleration slip regulation (ASR) module. The CAN is a serial data transmission

bus and the ASR is the traction control system. The display should read OK at all times. The

ASR system is disabled if the display reads NOT OK.

CAN RECEPTION FROM DAS

Range: _______________________________________________________ OK/NOT OK

Used on ERE/EVE/ASF (IFI Diesel)) systems. This parameter indicates whether the controller

area network (CAN) is receiving data from the DAS module. The display should read OK at all

times. A NOT OK reading indicates a loss of communication between the ECU and DAS module.

CAN RECEPTION FROM DI1

CAN RECEPTION FROM DI2

Range: _______________________________________________________ OK/NOT OK

Used on EZ and LH systems. These parameters indicate whether the controller area network

(CAN) is receiving data from distributor ignition modules 1 or 2 (DI1 or DI2). The display should

read OK at all times. A reading of NOT OK indicates a loss of communication between the ECU

and DI1 or DI2, which prevents ECU control of ignition.

CAN RECEPTION FROM EA,CC,ISC

Range: _______________________________________________________ OK/NOT OK

Used on EZ and LH systems. This parameter indicates whether the controller area network

(CAN) is receiving data from the electronic accelerator (EA), cruise control (CC) and idle speed

control (ISC) modules. The display should read OK at all times. A reading of NOT OK indicates a

loss of communication between the modules. When the display reads NOT OK, the electronic

accelerator, cruise control and idle speed control functions are disabled and default values are

being substituted.
