GENERAL INFORMATION

NOTE: Many 2009 model year Precedent vehicles have had the pedal group reworked to use an MCOR in place
of the throttle position sensor. If this is the case, see IQ System Troubleshooting – MCOR on page 12-1
or Excel System Troubleshooting – MCOR on page 14-1 for troubleshooting and system diagnosis. For
a vehicle that still uses the throttle position sensor, use this section.
Starting early 2010 model year with Serial Number PQ1009-082079, all electric Precedent vehicles were
factory-equipped with an MCOR sensor in the Gen II pedal group. The pedal group has its own serial number
with a prefix that also changed as follows:
Gen II pedal group equipped with throttle position sensor (before
reverting to MCOR):
Gen II pedal group equipped with MCOR:
The Excel System vehicle uses a 48-volt electrical system that is powered by four 12-volt lead-acid batteries or six
8-volt lead-acid batteries and includes an onboard computer. The Excel System vehicle uses a shunt-wound 3.2 hp
motor and includes several additional features.

DIFFERENCES BETWEEN THE EXCEL AND IQ SYSTEMS

• Excel is used in Precedent models only.
• Excel utilizes the 1515 controller instead of the 1510A.
• The Excel 1515 controller uses half-bridge technology allowing cooler operating temperatures and increased
motor braking.
• The Excel minimum motor braking speed has been lowered to almost zero.
• Excel has higher energy output during regenerative braking due to the lowered minimum motor braking speed.
• The Excel accelerator pedal has more control of downhill speed.
• When parked on a hill, the Excel vehicle resists sudden acceleration after the park brake is released.
