Symptom Chart.

(MIL) illuminate and DTC U2015 Signal Link Fault (Non SCP) occurs if

the ignition key is cycled OFF/ON before the anti-lock brake control

module completes its pump check. If this occurs, clear traction inverter

module (TIM) DTCs, turn the ignition key to the ON position, and wait for

the completion of the ABS pump check. Continue with this pinpoint test

only if TIM DTC U2015 occurs after the completion of the ABS pump

check.
