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.
NOTE:
Service information letter instructions published following the date of this document
take precedence.
