Uncontrolled Copy ID # CBR-15-9 Version 9 Print Title Diagnostic Trouble Codes (DTC) For The Engine Pre-Heat Relay: Supplementary Instructions Abstract For vehicles with US10+OBD13 and newer emissions (model year 2014 and newer), it is possible that when diagnosing an issue involving the engine pre-heat 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.

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 - 11L • 23122112 - 13L • 23122116 - 13L Impact should always be reviewed for the latest part information. 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. - If the software is current: Proceed to the next section. If all diagnostic steps indicate that the relay is the faulty component: • Replace both the Pre-heat relay ( P/N 23692384 ) and the Supply Power Cable. • For 13L models install the newly updated bracket design with 2 mounting locations ( P/N 23803412 ).
