2001-02 XG300/350 ECM REPROGRAMMING INSTRUCTIONS FOR P0139 & P0159 AND 2002 XG350 REPROGRAMMING FOR SMOOTHER
FEELING INITIAL ACCELERATION
NOTE:
This TSB supercedes 02-36-032. The ECM ID has been updated.
DESCRIPTION:
(1) CHECK ENGINE LIGHT ON -- DTC P0139 & P0159:
Some 2001-2002 XG300/350 vehicles may turn on the "Check Engine" light and have the diagnostic trouble codes P0139 and P0159 stored in the ECM.
^
DTC P0139: 02 Sensor Circuit Range/Performance Problem (Bank 1, Sensor 2)
^
DTC P0159: 02 Sensor Circuit Malfunction - Rationality (Bank 2, Sensor 2)
These diagnostic trouble codes can be set incorrectly under certain driving conditions. If the codes are set erroneously (the front 02 sensors function
normally when diagnosed using the Hi-Scan Pro), perform the ECM software reprogramming procedure using the Hi-Scan Pro as outlined below.
(2) SMOOTHER FEELING ACCELERATION:
The initial acceleration characteristics of some 2002 XG350 vehicles may not feel as smooth as some customers desire.
A previous TSB and ECM reprogramming addressed this condition (TSB # 02-36-007). This TSB and the accompanying ECM reprogramming makes
an ADDITIONAL improvement above and beyond the previous TSB, as well as a correction for the CHECK ENGINE LIGHT ON -- DTC P0139 &
P0159 condition.
