DTC 21: Cancel Latch Signal System

.

DTC SET CONDITIONS
The PCM communicates cancellation retention infor-
mation between the two microprocessors. This DTC 
is set when cancellation retention information con-
tains inconsistency.

.

TROUBLESHOOTING HINTS (The most likely 
causes for this code to be set are:)
Malfunction of the PCM.

DIAGNOSIS

.

Replace the PCM. (Refer to
