Jeep P1CBE: Pump Always On - Circuit Current Above Threshold
OVERVIEWWhat Does The Jeep P1CBE Code Mean?
This diagnostic checks the performance of the hydraulic pump. The Smart Driver Unit (SDU) which is external to the Transmission Control Module (TCM) drives the hydraulic pump based upon a PWM command signal received from the Transmission Control Module (TCM). This diagnostic uses three feedback signals. The PWM driver, internal to TCM, returns a command feedback signal. The SDU returns to the TCM the hydraulic pump driver feedback signal. The TCM separately receives the hydraulic pump feedback signal confirming the pump state.
What Are The Potential Causes Of The Jeep P1CBE Code?
- Pump command circuit shorted to ground
- Smart drive unit (SDU)
- Transmission control module (TCM)
