213301 - P160C

Fault text
Power management: Overvoltage

Fault description
The diagnostic function monitors the onboard electrical
system's voltage at the DME while the engine is running.

Condition for fault identification
Test condition:
The fault is recognized when the onboard electrical system's
voltage exceeds 16 V.
Potential problem source(s):
- With engine running, excessive voltage from:
- External charger/battery (jump-start from truck, 24 V)
- Defective voltage regulator
- °CU Power Control Unit defective, if present
- DME/DDE voltage measurement defective
Terminal condition: none
Voltage condition:
- Electrical system voltage greater than 16 V
Temperature condition:
- None
Time condition:
- None
Other conditions:
- Engine ON

Condition for fault memory entry
The diagnostic fault code is logged when the fault remains
present for longer than 1 min.

Action in service
- Ask customer if charge from external source/jump start has
been performed
- Check voltage regulator
- Determine whether diagnostic fault codes are logged in the
°CU.
- Determine whether internal control module faults have
been logged in the DME/DDE.

Fault effect and breakdown warning
Breakdown notice:
