** SOLUTION **
Cause
For vehicles with US10+OBD13 and newer emissions (model year 2014 and
newer), it is possible that when diagnosing an issue involving the engine preheat relay, performing a standard resistance check on certain versions of the
power cable with an ohm meter will not identify a cable that requires
replacement, potentially leading to repeated issues.
Solution
This solution does not apply to vehicles manufactured prior to
US10+OBD13 emissions. For vehicles with previous emissions levels, ONLY
the component found to be the cause of the issue should be replaced.
PARTS
Verify that an applicable part is currently installed. Affected Supply Power
Cable part numbers (current as of June 2019) are:
• 23122110
• 23122112

REPAIR
Prior to replacing the relay:
1. Complete diagnostic steps for the applicable code(s) in Premium Tech Tool.
2. Verify proper terminal tension of all connections at both the heating element
and the relay, including the plug-style connector.
3. Check for software updates available for the EMS:
- If there is a software update available: Update the software. Proceed to
the next section.
