Substitute a known good ECM and recheck.
Was the problem solved?
IMPORTANT: The replacement ECM must be
programmed. Refer to section of the Service
Programming System (SPS) in this manual.
Following ECM programming, the immobiliser system
(if equipped) must be linked to the ECM. Refer to

4JH1 ENGINE DRIVEABILITY AND EMISSIONS
Condition for setting the DTC and action taken when the DTC sets
Circuit Description
When the ignition switch is turned “Off”, the fuel
solenoid valve (MAB) signal is supplied from the ECM to
the PSG. This signal is the command for the PSG to
turn “Off” the engine.
If the MAB signal circuit is short to voltage circuit or
short to ground circuit, DTC P0215 (Symptom Code B)
or P0215 (Symptom Code C) will be stored.
Diagnostic Aids
An intermittent may be caused by the following:
• Poor connections.
• Misrouted harness.
• Rubbed through wire insulation.
• Broken wire inside the insulation.
Check for the following conditions:
• Poor connection at ECM and PSG-Inspect harness
connectors for backed out terminals, improper
mating, broken locks, improperly formed or damaged
terminals, and poor terminal to wire connection.
