SummarySymptoms/Condition: Shifter reports loss communication AND NO OTHER MODULES report the condition. Diagnostic: Please make sure ONLY shifter reports loss communication. If there are other modules reporting loss communication, then follow the existing service procedure Repair Procedure: 1. Verify Complaint - ESM reports a Loss of Communication (LOC) DTC, but no other modules do. - If multiple modules report the same LOC, the ESM is not the cause (its not a gateway module). 2. Read DTCs - Relevant codes: U0101, U0140, U0155, U0129, U11C3, U0402, U0422, U0423, U0415, U145D. - If multiple LOC DTCs are present: a. Check battery health, system voltage, and TCM (including valve body). b. If TCM goes offline, ESM may falsely report LOC DTCs. 3. Check Environmental Data - Look for voltage/system issues at the same mileage. a. If DTCs clear, do not replace ESM. b. If not, inspect: b.1 Module connectors/pins: If damaged, dont repair shifter. b.2 TCM connectors/pins: Same rule. b.3 AGSM connectors/pins: If damaged, repair shifter. b.4 AGSM wiring harness: If damaged, dont repair shifter. 4. Review Past Service - Confirm battery and TCM-related repairs are still effective. a. If not, fix and clear DTCs. b. If yes, continue. 5. Check for Other LOCs - If other modules report LOC to the same module, inspect that module. - If not, repair the AGSM. Additional Description: - The ESM only communicates with the TCM and is fully controlled by it. - In non-combustion engines, the TCM is replaced by the PCM. - If a stored DTC in the ESM disappears and doest return, do not replace the ESM.

Please follow the next steps to corroborate if the Headlamp Switch is malfunctioning: 1.- Please disconnect and reconnect the headlamp Switch. And verify if the issue is corrected. If it is the Instrument panel Dimmer (Right Dimmer) 2.- Review the resistance value between Pins 6 & 3. The value should be around 5.76 KOhms, when in the lowest position to 311 ohms in the top position (Parade Detent). If it is the ambient light dimmer (Left Dimmer) 2.- Review the resistance value between Pins 8 & 3. The value should be around 14.55 KOhms, when in the lowest position (Dome defeat) to 182 ohms in the top position If a problem is found in the resistor values. Please replace the Switch.
