HOW TO USE THIS MANUAL

This is a combined immobiliser diagnostic manual for all variants of SCORPIO (mHAWK and

m2DiCR).The manual is divided in to two parts. The first part outlines the procedure to be

followed when any of the components, viz keys, EMS ECU or immobiliser ECU(ICU), needs to be

replaced. The seconds part outlines the trouble shooting process.

The following is the structure of the Immobiliser Diagnostic Manual –

Combination of error codes

Reason

Check lamp status

Vehicle behavior

Probable cause

Trouble shooting steps

The DTCs for immobiliser are generated at the ICU as well as at the engine management

system (EMS) ECU. Hence it is essential that after looking at the DTC at ICU, the DTC at the

EMS ECU should also be checked. Based on the combination of DTCs, the possible causes and

the corrective actions to be taken.

It is also essential to clear the DTCs In both ICU and EMS ECU. The diagnostic manual should

always be used along with the vehicle’s wiring manual (MAN-OO268)
