SUBJECT OPTIMA HYBRID (TF HEV) WITH DTC B1695 - LOST

COMMUNICATION WITH E-COMP

Be sure to remove the hybrid battery safety plug before performing this repair, and
keep the plug in your possession until complete. If not, electric discharge injury may
result from High-Voltage (HV) current.

When addressing a customer concern related to an A/C system not blowing cold air and DTC
B1695 is active in the A/C Control Unit, this could be the result of one, or more, of the following
conditions:

e Ablown High-Voltage (HV) fuse in the E-Comp 270 volt supply circuit.
e Acircuit concern between the A/C Control Unit and the E-Comp
e AHigh-Voltage (HV) circuit concern

Begin the diagnosis process by locating the HV E-Comp fuse on the HPCU. The fuse is
located at the rear of the unit just above the 270V input to the HPCU. Once the fuse is
located, remove it and test for continuity across the fuse. If the continuity test reveals an open
circuit, order a replacement fuse. Note - If the fuse is blown, it is likely due to either a
harness or an E-Comp concern. Verify the root cause before replacing the fuse or it will
likely blow again. For additional diagnosis information, refer to the Service Information
on KGIS.

TECHNICAL SERVICE BULLETIN

SUBJECT: TCM UPGRADE — SHIFT LOGIC IMPROVEMENT

This bulletin provides information related to a TCM (Transmission Control Module) software
upgrade for some 2014~2015MY Cadenza (VG) vehicles, produced from February 11, 2013
through July 11, 2014 and from July 14, 2014 through December 12, 2014, to improve a
transmission shift concern that may be described as “hunting” and/or busy shift. This concern is
most prominently felt while climbing an incline with the Smart Cruise Control (SCC) engaged.
To resolve the concern, reprogram the TCM/PCM using the GDS/KDS download as described
in this bulletin. For confirmation that the latest reflash has been performed, verify ROM ID using

the tables in this TSB.

Global Diagnostic System (GDS)

* NOTICE

After performing the software upgrade, make sure to reset the TCM Adaptive Learning
Values by referring to TSB TRA 049.

All TCM/PCM upgrades must be done with the ignition key in the ‘ON’ position.

Be careful not to disconnect any cables connected to the vehicle or GDS during the
TCM/PCM upgrade procedure.

DO NOT start the engine during TCM/PCM upgrade.

DO NOT turn the ignition key ‘OFF’ or interrupt the power supply during TCM/PCM
upgrade.

When the TCM/PCM upgrade is completed, turn the ignition ‘OFF’ and wait 20

seconds before starting the engine.
ONLY use approved TCM/PCM upgrade software designated for the correct model,

* NOTICE

If performing this TSB using KDS, refer to TSB SST 037 for detailed information.

1. Connect the power supply cable to the GDS.

* NOTICE

If attempting to perform the TCM upgrade with the power supply cable
disconnected from the GDS, be sure to check that the GDS is fully charged before
TCM upgrade. If the GDS is not fully charged, failure to perform the TCM upgrade
may occur. Therefore, it is strongly recommended that the power supply
connector be connected to the GDS.

2. Connect the USB cable between the VCI and the GDS.

* NOTICE

When performing the TCM upgrade using the GDS, wireless communication
between the VCI and GDS is not available. Therefore, be sure to connect the USB
cable between the VCI and the GDS.

3. Connect the Main 16-pin DLC cable (GHDM — 241000) to the VCI.

4. Connect the Main 16-pin DLC cable
(GHDM — 241000) to the OBD-lII
connector, located under the driver's
side of the instrument panel.

With the ignition key ON, turn ON the VCI and GDS. Access the GDS vehicle identification
number (VIN) screen and configure the vehicle using the VIN AUTO DETECT Function.
