Series 60 – Low Power Troubleshooting Chart

There are three basic checks that should be performed:

Check for active/historic codes. All causes need to be checked once the fault is identified.
Record faults on the Application For Adjustment (AFA) claim, if there is to be a claim.
Check the DDEC parameters, progressive shift settings, torque limiting values, and injector
codes. Are they correct? Is proper rating applied? If vehicle is new, is it spec’d correctly?
Check that the dyno-measured power is within DDC specifications as Listed in Table 12-4
for minimum acceptable wheel HP data. Record data on AFA claim.

Service information letter instructions published following the date of this document take precedence.
Possible causes of low power and symptoms are listed in Table 12-2.
