Ignition Coil
Ignition coil codes will set if the ignition coil primary voltage is
out of range. This could occur if there is an open coil or loss of
power to the coil. If front and rear codes are set simulta-
neously, it is likely a coil power failure or a coil failure.
The coil receives power from the system relay at the same
time that the fuel pump and injectors are activated. The sys-
tem relay is active for the first 2 seconds after the ignition is
turned ON and then shuts off until RPM is detected from the
CKP sensor, at which time it is reactivated. The ECM is
responsible for turning on the system relay by providing the
ground to activate the relay, which in turn powers the coil.

Loss of TSM/TSSM Serial Data
The serial data connector provides a means for the ECM,
TSM/TSSM and speedometer to communicate their current
status. When all operating parameters on the serial data link
are within specifications, a state of health message is sent
between the components. A DTC U1255 (only reported by
the TSM/TSSM or speedometer) indicates that no messages
were present during power up of the current key cycle. A DTC

Loss of Speedometer Serial Data
The serial data connector provides a means for the speedom-
eter, ECM and TSM/TSSM to communicate their current sta-
tus. When all operating parameters on the serial data link are
within specifications, a state of health message is sent
between the components. A DTC U1255 (only reported by
the TSM/TSSM or speedometer) indicates that no messages
were present during power up of the current key cycle. A DTC
U1097 indicates that there was communication on the data
bus since power up, but was lost or interrupted during that
key cycle.
