1. GENERAL INFORMATION
The Powertrain Control Module (PCM) fitted to VT Series Models with the 5.0 litre V8 engine and Production Option
(P.O.) 9C1 is the same PCM as fitted to other VT Series Models with 5.0 litre V8 engines, noting the following:
To prevent the battery from discharging when vehicles are left idling for prolonged periods with electrical consumers
switched on, such as police lights, A/C etc., a modified PROM (MEMCAL) is fitted. With the modified PROM
installed, the engine idling and either neutral or park selected, the engine will idle at 850 RPM (compared to 650
RPM on standard Models).
The PROM can be identified by the broadcast code stamped onto the PROM, refer to the following table together
with the information contained in POWERTRAIN MANAGEMENT – V8 ENGINE of the VT Series I Service
