U0064-88: Vehicle Communication Bus E - Bus off: Action
WARNING:
The PHEV
battery pack casing must not be disassembled due to the risk of exposure to high voltage. Failure to comply with this instruction may result in personal injury or death.
NOTE:
Checking other control modules for related Diagnostic Trouble Code(s) may determine if the fault is localized to one control module or the entire network.
- Do not
replace the Battery Charger Control Module (BCCM) for this DTC
alone
- Refer to the electrical circuit diagrams and check the high speed CAN bus (power mode zero) circuit for short circuit to ground, short circuit to power, open circuit, high resistance. Repair the wiring harness as necessary
- Refer to the electrical circuit diagrams and check the relevant control module power and ground circuits for open circuit, high resistance. Repair the wiring harness as necessary. The relevant control modules are as follows:
- Battery energy control module (BECM)
- Powertrain control module (PCM)
- Electric power inverter converter module (EPIC)
- Gateway module (GWN)
- Using the JLR
approved diagnostic equipment, check the relevant control modules for related Diagnostic Trouble Code(s) and refer to the relevant DTC
index. The relevant control modules are as follows:
- Battery energy control module (BECM)
- Powertrain control module (PCM)
- Electric power inverter converter module (EPIC)
- Gateway module (GWM)
